Nodaform Reviews and Details

Questions & Answers

1. How would you describe the primary audience of Nodaform?

   Homeowners planning a renovation or a new home, real estate agents preparing listing plans, contractors and builders who need a quick measured drawing, and interior designers and architects who want fast concept plans, 3D views and client presentations. Engineering offices use the Ultimate plan for BIM data, clash detection, IFC export and electrical load simulation.

2. What makes Nodaform unique?

   Nodaform covers the whole small-building workflow in one browser tab: you draw a measured floor plan, and the same project gives you a 3D model with roof, building sections, elevations, electrical and plumbing layout, a structural pre-check, fire safety equipment with escape-distance checks, quantity take-off, a cost estimate and scaled PDF sheets. Everything is generated from one plan, so when the plan changes, every drawing and number updates with it. An AI assistant can edit the plan from plain-language requests, and AI render turns the 3D view into a realistic image. No installation, and the drawing tools are free.

3. What's the story behind Nodaform?

   Nodaform started as a small tool for sketching rooms to scale, because most floor plan apps either stopped at pretty pictures or required learning professional CAD software. It grew step by step from real use: multiple floors, 3D, sections and elevations, building services, structural and fire safety checks, sheets for print, and later AI features. It is built and run by an independent developer, and new features are added based on what users actually draw.

4. Why should a person choose Nodaform over its competitors?

   You don’t need to learn CAD. You type a measurement and the wall is drawn; dimensions follow architectural conventions (inside dimensions, wall thickness added outwards). The output is a drawing a builder can work with: 1:50 / 1:100 sheets with your own title block, vector PDF, DXF and IFC. It runs in any modern browser, is available in 12 languages, and the paid plans start at $4 a month, billed monthly or yearly with no long-term contract.

5. Who are some of the biggest customers of Nodaform?

   • Homeowners and renovators
   • Real estate agents
   • Contractors and builders
   • Interior designers and architects

6. Which are the primary technologies used for building Nodaform?

   • Custom 2D drawing engine (JavaScript, HTML5 Canvas): built from scratch around architectural rules. It handles inside dimensions with wall thickness added outwards, detects corners and T-joints, and snaps doors and windows into walls. Every symbol is drawn to real size in centimetres.
   • One plan, many drawings: a single plan data model with multiple floors drives the 2D plan, the 3D model, sections, elevations, sheets and reports. A change in the plan updates all of them.
   • Procedural 3D with Three.js: walls, slabs, stairs, roofs (flat, shed, gable, hip), window frames and sills are generated from the plan. It includes a first-person interior walkthrough and a library of 374 parametric 2D/3D objects.
   • In-browser engineering checks: a structural pre-check for columns, beams and slabs; electrical circuit analysis with voltage drop and three-phase balance; grid-based shortest-path search for fire escape distances; BIM clash detection and quantity take-off.
   • AI with structured outputs: the assistant (Anthropic Claude) returns a validated list of plan changes, applied as one undoable step. AI render (Google Gemini) receives the 3D view plus a generated scene description, so the image stays faithful to the plan.
   • Server-side exports: vector PDF sheets, DXF and IFC 2x3 are generated on Cloudflare Workers.
   • Edge infrastructure: Cloudflare Workers and D1 for the API, accounts, projects and sharing; Turnstile for bot protection.
   • Build-time localisation: one source language is compiled into 12 languages with separate URLs.
