Plasticity vs Shapr3D

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.

Shapr3D is a professional 3D CAD modeling app built on the Siemens Parasolid engine, the same solid-modeling foundation used in professional CAD systems. It combines push-pull direct modeling with sketch-based parametric constraints, and it is unusual in supporting native Apple Pencil and Windows pen input so users can sketch 3D geometry the way they would sketch on paper, in addition to running as a conventional desktop app. The app includes built-in AR for placing full-scale models in the real world, generates 2D technical drawings for manufacturing handoff, and imports/exports common formats including STEP, IGES, SLDPRT, SLDASM, STL, and 3MF. Cloud team spaces add shared projects and browser-based review links, and Apple Vision Pro support lets users review models immersively. It targets industrial and product designers, manufacturing teams, and makers who want manufacture-ready models without a purely desktop-bound workflow.

• 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

• Runs natively on iPad with pen input, which is unusual for professional-grade parametric CAD.
• Free Basic plan supports real, exportable modeling work on up to 2 projects, not just a crippled demo.
• AR and Vision Pro viewing make it easy to check real-world scale and fit before manufacturing.
• Cross-platform license covers Mac, Windows, and iPad from one subscription.

• 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

• Pro plan is priced per editor seat annually, which adds up for small teams needing several licenses.
• Free tier caps renders and projects, so serious ongoing work quickly requires the paid plan.
• Less mature simulation and assembly tooling than desktop-only incumbents like SolidWorks or Fusion 360.
