FAQ — 200+ Frequently Asked Questions — GorkyCAD Pro

GorkyCAD Pro is an intelligent engineering operating system for building electrical supply design. It is not just a CAD, not a graphics editor, and not an AI chat. It is a single engineering model where the floor plan, single-line diagram, panel, BOM, estimate, PDF and 3D are all derived from one model.

AutoCAD Electrical is a tool for drawing electrical schematics. GorkyCAD is an engineering model. In AutoCAD, you draw lines and symbols; in GorkyCAD, you create an engineering model from which the schematic, plan, panel, BOM, estimate and PDF are automatically generated.

EPLAN Electric P8 is powerful but very expensive and complex. GorkyCAD offers the same automation level, but in the browser, with AI assistant, at a 10-20x lower price. Key difference: GorkyCAD uses a unified engineering model.

For free use, minimal registration (email) is needed. You can also work fully offline without registration — projects are saved locally.

GorkyCAD supports standards of Russia (GOST, PUE), India (IS 732, IS 1646) and international (IEC 60364). Interface in Russian, English and Hindi. Pricing in RUB, USD and INR.

Because GorkyCAD is an engineering model, not a drawing tool. In CAD you draw lines. In GorkyCAD you build a model that auto-syncs plan, schematic, panel, BOM, estimate and 3D. Plus built-in AI checks your project against standards and explains calculations.

GorkyCAD is developed by a team of design engineers and programmers. It was born from a real need: to automate the routine of electrical design. The name references Nizhny Novgorod (Gorky), where development began.

GorkyCAD has passed 4000+ automated tests (unit + integration + E2E). The calculation engine is stable. Active development continues (releases every 2-4 weeks). Current beta — already suitable for real apartment and house projects.

Click "Create Project", select a template or blank project. Start with the floor plan: draw walls, add rooms. Then place outlets, switches and lights. The system builds the schematic and generates documentation. First result — in 2 minutes.

Chrome, Firefox, Edge, Safari, Opera. We recommend Chrome or Edge. Mobile browsers are supported in view mode.

Auto-save every 30 seconds. Format — .gorkycad (ZIP + JSON). Export to a file to open on another computer. Offline data is stored in browser IndexedDB.

Yes, via DXF import. The floor plan imports as a basis. Electrical objects need to be placed in GorkyCAD — DXF symbols are just graphics, not engineering objects.

Select the "Wall" tool, click at the start point, drag to the end. Walls can be orthogonal (90° snap) or freeform. Thickness and material are configurable. Closed contours automatically create rooms.

Select "Door" or "Window" from the toolbar, click on a wall. The object automatically snaps to the wall. Configure size, opening direction, material.

The "Dimension" tool places linear dimensions between walls. Dimensions update automatically when geometry changes. Callouts and text annotations are available.

Outlets (power, low-current), switches (single/double/pass-through), lights (ceiling/wall), junction boxes, panels (main, sub, floor, apartment), cable lines, MCBs, RCDs, RCBOs, isolators. All objects have engineering properties, not just symbols.

Select "Outlet" in the panel, click on a wall. It snaps automatically. Set installation height, rated current, group. For free placement — use the free positioning mode.

Yes. The library contains symbols per GOST 21.614, GOST 21.210, PUE (Russia), IS 732 (India), and IEC 60617 (international). Select the standard in project settings.

The system analyzes the schematic: how many groups, which MCBs, RCDs, RCBOs. Then automatically layouts the panel: DIN rails, devices in correct order, phase busbars. PUE/IS clearances are observed. The result can be manually adjusted.

Auto busbars are automatic phase connections between MCBs. Instead of manual wiring, the system lays busbar connectors between MCB rows. Phase rotation (L1/L2/L3) and busbar cross-section by total current are accounted for.

Feeder Topology is the panel hierarchy: main panel → sub-panel → floor panel → apartment panel. The system tracks connectivity automatically and calculates cumulative loads across the hierarchy.

Auto routing lays cables from the panel to each outlet/light via the shortest path, avoiding obstacles (walls, openings). It accounts for: installation method (chased, trunking, exposed), height, and crossings with other services.

Cross-section is calculated by two criteria: 1) heating (continuous current rating per IEC table / IS 732), 2) voltage drop (max 5% from main panel to end consumer). The larger of the two is selected, rounded to the nearest standard size.

Yes. After auto routing, you can manually drag route nodes, add intermediate points, change installation method on specific segments. Cable length recalculates automatically.

Automatically: load calc (Pinst, Pcalc, Icalc), cable sizing by heating and voltage drop, S/C currents (1ph + 3ph), voltage drop check, selectivity check. All deterministic (not LLM), guaranteed repeatability.

GOST R 50571, PUE 7th ed., SP 256.1325800, IEC 60364, IS 732. Select the standard in project settings. You can switch and compare results.

Yes. All calculations are transparent: inputs, formulas, intermediate values, final result. The AI assistant explains step by step. Export calculations to PDF.

Deterministic engine means calculations are done by formulas (not AI/LLM). Same input always produces same output. This is critical for engineering, expert review and legal disputes. AI is only for explanation and checking, not calculation.

Per IEC 60909 / IS 13234. Accounts for: transformer impedance, cable impedance from transformer to S/C point, contact resistance. Calculates: three-phase (Isc³), single-phase (Isc¹), peak current. Result used for MCB sizing and selectivity check.

Demand factor (Kd) is the ratio of calculated load to installed load. For apartments: Kd = 0.3–0.8 depending on count. Offices: Kd = 0.5–0.9. GorkyCAD applies Kd automatically from standard tables, with manual override.

Yes. Derating factors are applied: number of cables in bundle, installation method (conduit, tray, chased), ambient temperature. Per IEC 60364 / IS 732 derating tables.

PDF set generated with one button: electrical floor plan, single-line calculation diagram, panel schematic, BOM, cable schedule, estimate, calculation results.

PDF (complete set), DXF (for AutoCAD), CSV (BOM, cable schedule, estimate), HTML (interactive view), .gorkycad (native format for sharing). Pro plan adds DXF and extended PDF.

Yes. The PDF set complies with GOST R 21.101 (SPDS), GOST R 21.613 (power equipment) — Russia; IS 732 — India; IEC — international. Stamps, frames, symbols — all compliant.

The AI assistant checks GOST/PUE/IS compliance, explains calculations, gives optimization recommendations, performs semantic search. AI works locally, without sending data to a server.

Calculations are deterministic (formulas, not LLM). For checks and explanations, AI uses a local model, not a cloud LLM. Future — optional cloud LLM for complex queries, but by default everything works offline.

AI standards checking is not probabilistic. It is a deterministic check against formalized rules (GOST/PUE/IS requirements). Accuracy — 100% for formalized rules. For informal recommendations, AI shows confidence level.

Team: project dashboard (status, timeline, budget), solution statistics, labor costs, planned vs actual cost. Export to PDF for presentations.

Floor plan via DXF import (walls, rooms). Electrical objects must be re-placed — DXF symbols lack engineering data. Bulk BOM import via CSV.

Export to PDF or HTML. HTML opens in any browser with interactive view. DXF — for CAD systems. Send view link via Telegram/WhatsApp.

Partially. Import: DXF from Revit. Export: IFC (Team plan). Full BIM integration — in Roadmap. We recommend GorkyCAD as a specialized electrical tool alongside architectural BIM.

The installation diagram shows exact placement of all elements: outlets (with height), switches, lights, junction boxes, cable routes. The cable schedule contains types, cross-sections and lengths. BOM — complete equipment list for procurement.

Yes. Cable sizing accounts for installation method: chased (in plaster), in conduit, corrugated, on tray, exposed, underground. Each method has derating factors per IEC 60364-5-52.

Yes. GorkyCAD generates a connection diagram for each junction box: which cables enter, which cores connect to which. Especially useful for complex lighting with pass-through switches.

The BOM is auto-generated from the model: outlets (by type), switches, lights, cable (total length by cross-section), MCBs, RCDs, panels, DIN rails, busbars, junction boxes. The estimate adds labor costs (man-hours × rate).

GorkyCAD automatically checks the project against formalized requirements of IEC 60364, PUE, GOST, IS 732. However, the engineer bears responsibility. GorkyCAD is a tool that highlights potential violations and suggests fixes. Final decision rests with the designer.

GorkyCAD verifies: RCD trip time (≤ 0.4s per IEC), phase-neutral loop impedance, earthing and equipotential bonding. Single-phase SC current is calculated for each group and compared with MCB characteristics.

Yes. Verified: cable heating (must not exceed rating), panel contact heating, cable spacing (fire breaks), room fire hazard category. India: IS 1646. Russia: SP 6.13130 and PUE Chapter 7.

GorkyCAD supports SPD (Surge Protective Device) calculation and placement — IEC 61643. Three protection classes: Class I (main), Class II (distribution), Class III (end equipment). Voltage and energy coordination.

Yes. AI assistant analyzes phase loading, suggests balancing, finds overloaded lines, and recommends optimal cross-sections to reduce losses. Cable loss calculation (I²R) estimates annual wire heating costs.

The equipment catalog shows energy efficiency class for each device. AI can suggest alternatives: LED instead of incandescent, VFDs for motors, breakers with lower own consumption.

Yes. Each load has cos φ (default: 0.92 residential, 0.85 industrial). Calculated: active P (kW), reactive Q (kVAr), apparent S (kVA). For low cos φ, AI suggests reactive power compensation (capacitor banks).

Yes, REST API is available on the Team plan. Via API you can: create/edit projects, get BOMs, export PDFs, integrate with ERP systems (SAP, 1C), upload estimate data. API docs — in the Docs section.

Yes. BOM and estimate — CSV (opens in Excel, Google Sheets, 1C). Cable schedule — CSV with columns: route, type, cross-section, length. Estimate — CSV grouped by sections. Team: JSON API for direct ERP integration.

Revit plugin — in Roadmap (2027). It will sync GorkyCAD electrical model with Revit architectural model. AutoCAD — via DXF. No direct AutoCAD plugin planned, as GorkyCAD replaces its functionality.

Open app.gorkycad.pro in Chrome or Edge. An install icon (⊕) appears in the address bar — click it. Or via browser menu: "Install app" / "Add to Home Screen". PWA installs in seconds, ~15 MB, with its own taskbar icon and window. After install, GorkyCAD works offline — all data and AI are local.

Browser IndexedDB stores: all projects (.gorkycad), user settings, reference cache (equipment catalog, IEC/GOST/IS tables), AI model (~50 MB), undo/redo history, keyboard shortcuts and UI preferences. Max capacity: Chrome — up to 60% free disk space, Firefox — up to 2 GB per domain (extendable).

Offline-first sync: you work locally, all changes saved in IndexedDB. When internet appears (or via "Sync" button), delta is sent to cloud. Conflicts resolved by "last-write-wins" with manual version selection option. Incremental — only changes transferred. Team users get: sharing, version history, edit locking.

Clearing cache (images, scripts) does not affect IndexedDB — projects survive. However, clearing "all site data" (including IndexedDB) will irreversibly delete local projects. We recommend: 1) periodically export projects as .gorkycad files (one button), 2) enable cloud sync (Pro/Team), 3) set up auto-export to cloud storage via Webhook (Team). Data loss warning is shown in Settings.

Yes. Export the project as a .gorkycad file (essentially ZIP with JSON inside) on the first device, transfer by any method (USB, email, Telegram, AirDrop) and open on the second. The file contains the complete model: plan, schematic, calculations, panel, BOM. Typical apartment project size — 50–500 KB. For regular transfers, Team users get cloud Workspace with auto-sync.

Yes, fully. The AI model (~50 MB) downloads on first PWA install and is stored locally in IndexedDB. Standards checking (GOST/PUE/IS), calculation explanation, object search — all work offline. Cloud LLMs (GPT, Claude) are optional for complex queries like "design office lighting per BREEAM" — they require internet and a Pro+ subscription. But basic AI is entirely local.

Automatically. The Service Worker checks for a new version on every launch (or every 6 hours during active work). If an update is found, it downloads in the background (5–30 MB) and applies on next launch. A notification appears in the bottom-right: "New version available. Restart?" Critical security updates are applied forcefully. Projects are unaffected.

Yes, this is a key scenario. Install PWA on a laptop or tablet before going to the site. On-site, even without internet, you can: open the project, view the installation diagram, check outlet heights and cable routes, add notes (photo + comment per element), adjust placement as-built. Back at the office — sync with the main project. The foreman can show the client a 3D view right on the tablet.

PWA is the same site, but in a separate window with file system access, offline storage, and push notifications. Advantages over native: no store install, silent updates, smaller footprint, cross-platform (Windows/macOS/Linux/ChromeOS). PWA limitations: no COM port access (for measurement instruments), limited filesystem. Native apps (App Store/Google Play) — in Roadmap for 2027 for iOS/Android.

In the Team plan, multiple engineers can work on one project simultaneously. Editing uses granular locking: if one user edits the panel, another can work on the floor plan. Object-level locking (outlet, MCB, route). Conflicts are auto-resolved via a CRDT-like engine (Conflict-free Replicated Data Types). Changes are visible to all participants in real time via WebSocket.

Four roles: Owner — full control including project deletion and role assignment; Editor — full model editing, but cannot delete the project; Commentator — view and comments only (useful for clients or reviewers); Viewer — read-only. Each role can additionally restrict access to financial data (estimate) and export.

Every save creates a version (snapshot). All versions stored for 90 days (Free — 10, Pro — 100, Team — unlimited). You can: view any version read-only, compare two versions (diff), rollback to a previous version (creating a new branch to preserve current work). Version labels: "Before client approval", "Copper cable option", etc.

Yes. Comments attach to a specific element (outlet, MCB, route) and appear as markers on the plan/schematic. Format: text + attachment (screenshot, site photo). Comments have statuses: open, in progress, resolved. New comment notifications — in the UI and via email (optional). This replaces messenger chats like "check the outlet in the bedroom left of the window".

GorkyCAD uses multiple protection levels: 1) Granular locking — same object cannot be edited simultaneously. 2) "User X is editing this element" notification with avatar. 3) Color-highlighted responsibility zones: each engineer sees which floor or panel a colleague is working on. 4) Automatic CRDT merge for non-overlapping changes. 5) Manual conflict resolution with visual diff for overlapping edits (rare).

Yes. The PDF set can include comments (as margin callouts). The HTML version for clients shows comments interactively: click a marker — the discussion expands. The client can reply directly in the HTML version (no registration) — replies sync back to the engineer's project. This dramatically speeds up the approval process.

Basic Team — up to 10 users. Enterprise Team — up to 100 users with a dedicated server. Additional +5 user slots can be purchased. The admin sees: who logged in when, what changes were made (audit log), time spent in the project. Guest access (Viewer) does not count toward the limit — unlimited clients/reviewers can be invited.

The audit log (Team) records every action: who, when, which element, old value → new. Records are immutable (append-only), stored for 1 year. Filtering: by user, by date, by action type (create/modify/delete/export). Export the audit log to CSV for internal audits or ISO 9001 certification. The audit log is a legally significant document in disputes.

By default — locally in your browser's IndexedDB. Data never leaves your device. With cloud sync enabled (optional, Pro/Team), data is stored in data centers in Russia (for RF users — complies with 152-FZ on personal data), India (for compliance with the upcoming Data Protection Act), and EU (Frankfurt) for international users. You select the storage region at registration.

No. Your projects are your intellectual property. We do not use user projects for AI model training. Local AI runs exclusively on your device. Cloud LLMs (optional) receive only anonymized context of the current query and do not store it. This is stated in the Privacy Policy (Section 6.3) and License Agreement (Section 4.2).

Data transmission: TLS 1.3 (HTTPS) — mandatory, no opt-out. Cloud storage: AES-256-GCM (at rest), encryption keys managed via HSM (Hardware Security Module). Local storage (IndexedDB) — data is not additionally encrypted (we rely on OS disk encryption), but .gorkycad files can be password-protected (AES-256-CBC). For high-security organizations — on-premises deployment option (Enterprise).

Yes. GorkyCAD is GDPR compliant: data stored in the selected region (including EU), users can request export or full deletion of all data (one click in account settings), minimal data processing (only what is necessary for operation), a Data Protection Officer is appointed (dpo@gorkycad.pro). Russia: 152-FZ compliant. India: ready for the Digital Personal Data Protection Act 2023.

Settings → Account → Delete account. Process: 1) Export projects (single .zip archive). 2) Confirm deletion with an email code. 3) All cloud data is hard-deleted within 24 hours (no recovery possible). Local browser data must be cleared separately (instructions provided). The audit log (Team) is kept for 30 more days for compliance, then also deleted.

Yes. All browser-to-server traffic is encrypted via TLS 1.3 (HTTPS). EV (Extended Validation) certificates. HSTS (HTTP Strict Transport Security) is enabled — the browser will refuse insecure HTTP connections. In fully offline mode (PWA), no data is transmitted over the network at all. Recommendation: always verify the 🔒 padlock in the address bar.

Yes, for Enterprise clients (50+ users). On-premises deployment: Docker containers on your Linux server, all data stays within the organization's perimeter, integration with corporate SSO (LDAP, Active Directory, SAML), audit log — to your SIEM system. Minimum requirements: 4 vCPU, 16 GB RAM, 100 GB SSD. Updates are delivered as Docker images. Deployment SLA — 5 business days.

Yes. 2FA via TOTP (Google Authenticator, Authy, Microsoft Authenticator) or email code. For Team accounts, 2FA is mandatory. FIDO2/WebAuthn hardware keys supported (YubiKey, Titan). Enterprise: integration with corporate SSO (Okta, Azure AD) with conditional access policies. We recommend enabling 2FA immediately after registration.

The template gallery includes: studio apartment, 2–4-room apartments, private house (up to 200 m²), open-space office (up to 100 m²), café/restaurant, retail pavilion, garage/workshop. Each template contains: a ready floor plan, code-compliant electrical layout, a pre-configured panel, cable routes, and a BOM. Templates can be modified — they just speed up the start.

Yes. A completed project can be saved as a template: Project → Save as Template. The template saves: wall geometry, typical electrical layout, panel configuration, standard settings (GOST/IEC/IS). When creating a new project from a template, you can scale it (e.g., "2-room 60 m² apartment" template scaled to "3-room 80 m²"). Team users can publish templates for the entire organization.

Standard solutions are ready-made blocks: "Standard Kitchen" (6 outlets + lighting + underfloor heating), "Bathroom" (washing machine + boiler + exhaust fan), "Bedroom" (lighting + pass-through switch + A/C). Drag a block onto the plan — all objects and connections are created automatically. Blocks contain preliminary load calculations and cable cross-sections. Create your own solutions (Pro/Team).

Batch editing — changing properties of a group of objects at once. Select multiple outlets (Shift+drag) → change installation height, group, rated current — in one action. Mass replacement: "all 16A MCBs → 20A" or "all PVC cables → XLPE". Batch operations: group assignment, renaming, standard symbol switching (GOST/IEC/IS), cross-section recalculation. Saves hours on large projects.

Yes, two automation levels: 1) Macros (Pro/Team) — record a sequence of UI actions and replay. Example: "Select all outlets in a room → assign group → check cross-section → export PDF fragment". 2) Scripts (Team) — JavaScript API for complex logic: project generation from a CSV load table, pre-export auto-validation, custom reports. Docs: docs.gorkycad.pro/scripting.

Yes, via CSV import (Pro) or Script API (Team). Upload a table: "Room, Type, Pinst, cos φ, Kd" — the system automatically: creates rooms, places basic electrical, selects MCBs and RCDs, calculates cable cross-sections, layouts the panel. The result can be refined manually. This reduces project creation from days to minutes.

Before PDF/DXF export, a "Pre-flight check" runs: 1) Are all objects connected (no dangling outlets)? 2) Any overloaded MCBs? 3) Is voltage drop ≤ 5% everywhere? 4) Is selectivity correct? 5) Any empty fields in the BOM? 6) Are installation heights correct? The result is a list of warnings and errors. Export is blocked on critical errors. Customizable check rules (Team).

Yes. Designate one floor as "typical", assign a repetition rule ("floors 3–17 = typical floor 2"). When the typical floor is modified, all instances update automatically. The PDF set is generated for all floors at once; the cable schedule sums lengths across risers. This is a key feature for multi-apartment buildings and office towers.

Step by step: 1) In AutoCAD Electrical, export the floor plan to DXF (wall geometry only). 2) Import the DXF into GorkyCAD — walls and rooms are auto-recognized. 3) AutoCAD electrical symbols lack engineering data, so they need to be re-placed. However, this is compensated by speed: auto-routing, auto-panel, auto-calculation. 4) The AutoCAD BOM can be imported via CSV for verification. A typical apartment project: 2–3 hours for full migration.

EPLAN → GorkyCAD migration: 1) Export EPLAN macros as DXF (if you have a plan) or start fresh in GorkyCAD. 2) Export BOM and cable schedule from EPLAN to Excel/CSV. 3) Import CSV into GorkyCAD for automatic panel structure and cable connections. 4) The AI assistant will verify the migrated model against standards. Key advantage: after migration, you have a unified model instead of a set of EPLAN macros. EPLAN license savings: ~$4,000/year.

KOMPAS-Electric → GorkyCAD: 1) Export drawings to DXF (KOMPAS supports DXF export). 2) Import DXF as the plan basis. 3) Save the KOMPAS BOM to Excel (KOMPAS can export to XLS) and import into GorkyCAD via CSV. 4) The panel schematic will need manual rebuild, but auto-assembly will compensate the time. 5) Verify calculations: GorkyCAD will recalculate loads, cross-sections, short-circuit per the same GOST standards. Average project migration time: 3–5 hours.

Revit → GorkyCAD: 1) Export the floor plan from Revit to DXF (2D view). 2) Import DXF into GorkyCAD. 3) If Revit has electrical loads (panels, circuits), export them via Revit Schedules to CSV and import into GorkyCAD. 4) Place electrical objects in GorkyCAD — auto-routing and auto-assembly will do the heavy lifting. 5) The result can be exported back to BIM via IFC (Team plan). In Roadmap — a direct Revit plugin for bidirectional sync.

nanoCAD → GorkyCAD: nanoCAD uses DWG/DXF format, so migration is identical to AutoCAD: DXF export, GorkyCAD import, manual electrical placement. The advantage for nanoCAD users: GorkyCAD provides calculations and AI that nanoCAD lacks. The nanoCAD (architecture) + GorkyCAD (electrical) combo is a cost-effective solution for small design bureaus.

Partially. GorkyCAD uses its own built-in symbol library (GOST/IEC/IS). However, you can add custom symbols: SVG file + engineering properties (in JSON). Bulk import of custom symbols — via ZIP archive. Important: a GorkyCAD symbol is not just an image but an engineering object with electrical parameters (rated current, number of poles, connection diagram). Therefore, simple DXF block migration is impossible — customization is needed.

Estimated full migration time (plan + electrical + panel + documentation): apartment (50–100 m²) — 2–4 hours; private house (150–300 m²) — 4–8 hours; office floor (500–1000 m²) — 8–16 hours; apartment building (typical floor) — 16–24 hours. After migration, you save 50–70% time on every subsequent change due to the unified model. Team users get "Assisted Migration" — a support engineer helps migrate the first project.

Paper drawings → GorkyCAD: 1) Scan or photograph the plan at high resolution. 2) Import the raster image as a backdrop in GorkyCAD (JPEG/PNG, up to 20 MB). 3) Scale the backdrop by a known dimension (e.g., a load-bearing wall length). 4) Trace walls with the "Wall" tool over the backdrop. 5) Place electrical objects. This is manual, but the AI assistant will help: recognize rooms by contours, suggest typical outlet and switch placement.

Public Roadmap: gorkycad.pro/roadmap. Divided into three horizons: "Now" (current quarter — in development), "Next" (next 2 quarters), "Future" (1 year+). Each feature has a status (planned/in progress/beta/released) and expected plan tier (Free/Pro/Team). Pro subscribers get early beta access. Feature voting — via the Roadmap (one vote per project in your account).

Priorities for 2025–2026: 1) BIM export IFC 2x3 and IFC4 (Team) — Q2 2025. 2) Revit plugin for bidirectional sync — Q4 2025. 3) Lighting calculation (utilization factor method, DIALux-like) — Q3 2025. 4) Native mobile app for iOS/Android — Q1 2026. 5) "Extra-low voltage systems" module (structured cabling, access control, CCTV) — Q2 2026. 6) BIM Collaboration Format (BCF) integration — Q3 2026.

Yes, in the 2026 Roadmap. Planned: structured cabling systems (RJ45 outlets, patch panels, fiber optics); access control systems (readers, controllers); fire and security alarm systems (detectors, panels); CCTV (cameras, NVRs). All low-current systems will be part of the unified model: crossings with power cables, shared routes, a unified BOM.

Yes, in Roadmap (Q1 2026). The "Lightning Protection" module will include: protection zone calculation via the rolling sphere method (IEC 62305), down conductor sizing, protection class selection (I-IV), earthing grid design (vertical/horizontal electrodes, resistance to ground). 3D visualization of the protection zone on the building model. For India — IS 2309.

In the long-term Roadmap (2027+). A circuit diagram editor is planned with support for relay logic, PLCs (Programmable Logic Controllers), and VFDs. The goal is to close the chain: floor plan → power scheme → automation scheme → panel → documentation. Current focus — building power electrical.

On the Roadmap page, each planned feature has a "Vote" button. Number of votes = number of active projects in your account (more projects → more votes). You can also suggest a new feature via the "Feature Request" form — it appears in the "Under Consideration" section. Every quarter, the team revises priorities based on voting. The top 3 requested features get "Priority" status.

Beta testing is open to all Pro subscribers: Settings → Labs → enable the features you're interested in. Beta features are marked ⚡ and may be unstable. For each confirmed bug, subscription days are credited (+1 day for minor, +7 days for critical). The feedback channel is the Telegram beta chat. Every month — a yearly subscription raffle among active testers.

Engineering software is not a "move fast and break things" startup. Each feature must: pass engineering verification (calculations are manually checked against GOST/PUE/IS), have 100% deterministic repeatability, not break existing projects (4000+ auto-tests). For example, the short-circuit module requires verification against 200+ test scenarios. Priority: stability > new features. We prefer to release fewer but more reliable features.
