3D House Planner vs Plasticity
Side-by-side comparison of features, pricing, ratings, and alternatives.
3D House Planner is a free, browser-based 3D home design and architectural floor planning application. It allows users to build apartments and houses using intuitive sketching tools, import 3D models, apply realistic materials and textures, generate floor plans from images with AI assistance, and create snapshots or videos of their designs. It emphasizes privacy: no login is required, no cloud storage is used, and design data stays on the user's device.
Plasticity is a 3D modeling application described by its makers as CAD for artists, blending NURBS surfacing and solid modeling with a fast, freeform workflow more familiar to game and film artists than traditional engineering CAD. It runs on the Parasolid geometry kernel, the same kernel used by SolidWorks and Shapr3D, giving it precise boolean operations and clean surfacing. The software includes a live Blender Bridge for round-tripping models into Blender, SpaceMouse support, and import/export for formats including STEP, IGES, OBJ, FBX, STL, and 3MF. Plasticity is sold as a perpetual, one-time license across Indie and Studio editions with a 30-day free trial, and runs natively on Windows, macOS (Intel and Apple Silicon), and Linux.
The page explicitly states the product is free to use for all. No paid tiers or other pricing are mentioned.
- Completely free to use for personal and commercial purposes
- No installation required — works directly in the browser
- No login or account needed, preserving user privacy
- Design data stays on the user's device with no cloud storage
- One-time perpetual license instead of a recurring subscription
- Uses the same Parasolid kernel that powers professional CAD tools like SolidWorks
- Native Blender Bridge simplifies round-tripping with Blender pipelines
- Cross-platform support including Linux, which many CAD tools skip
- No cloud storage or auto-save: users must manually export/import to preserve work
- Not a full BIM (Building Information Modeling) tool; focused on visual 3D modeling and floor plans
- Some 3D assets are under CC BY-NC-SA license, which may limit certain commercial uses
- Advanced features like AI floor plan generation may require internet access and may not be as robust as dedicated AI tools
- Lacks the deep engineering/simulation feature set of full CAD suites
- Smaller plugin and asset ecosystem than long-established 3D applications
- Some import formats such as DXF/DWG are Windows-only

The Verdict
AI-generated from listing dataPlasticity is a paid, professional‑grade NURBS/solid CAD tool for designers needing deep modeling and cross‑platform desktop apps; 3D House Planner is a free, browser‑based home‑design app for quick visual floor plans with no subscription or installation.
Key differences
- •Pricing model: Plasticity requires a one‑time purchase; 3D House Planner is completely free.
- •Target use‑case: Plasticity offers NURBS and solid modeling for product design; 3D House Planner focuses on architectural floor‑plan sketching and interior visualization.
- •Platform & installation: Plasticity runs as a native desktop app on Windows, macOS, Linux; 3D House Planner runs only in a web browser, no install.
- •Integration ecosystem: Plasticity includes a live Blender Bridge and supports many CAD exchange formats (STEP, Parasolid, IGES, etc.); 3D House Planner offers limited import formats (GLB, GLTF, OBJ, Babylon) and no CAD‑level interoperability.
- •Data privacy & storage: Plasticity stores files locally on the user's machine; 3D House Planner stores no data in the cloud but requires manual export to preserve work.
