The short version

  • Only Unity AR Foundation has a free tier, so it costs nothing to try first.
  • Each has a real cost: Plasticity limited plugin ecosystem compared to Rhino; fewer third-party extensions available; Unity AR Foundation requires platform-specific plugins (ARCore, ARKit) to actually implement AR features
  • They diverge on capability: Plasticity covers Smooth surface modeling, Unity AR Foundation covers Plane detection.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Plasticity

  • Limited plugin ecosystem compared to Rhino; fewer third-party extensions available
  • Young product with shorter track record; fewer industry case studies and community resources
  • No parametric history tree; may require different workflow for some users accustomed to feature-based modeling
  • Premium pricing for Indie users despite being positioned as affordable alternative

Unity AR Foundation

  • Requires platform-specific plugins (ARCore, ARKit) to actually implement AR features
  • Performance varies significantly by device, with battery drain and heat generation on mobile
  • Emulators cannot accurately test AR experiences due to missing camera and sensor data
  • No WebXR support for browser-based AR experiences
  • Occlusion features show lower performance at 25-40 FPS compared to other features at 40-60 FPS
  • Limited access to latest platform-specific features compared to native ARKit or ARCore

Answered from the vendors’ own pages

Plasticity: What is Plasticity designed for?

Plasticity is a NURBS-based 3D modeler designed for concept and product design, prioritizing an artist-friendly workflow over parametric history-based modeling.

Source
Unity AR Foundation: Is Unity AR Foundation free?

Yes, AR Foundation is free and included with Unity. It is a package within the Unity engine, though you need a Unity license (available free for personal use with under $200K revenue).

Source
Plasticity: What platforms does Plasticity support?

Plasticity runs on Windows, macOS (Intel and M-Series), Linux, and Ubuntu using Parasolid's geometric modeling kernel.

Source
Unity AR Foundation: What platforms does AR Foundation support?

AR Foundation supports iOS (via ARKit), Android (via ARCore), visionOS, HoloLens 2 (via OpenXR), and Meta Quest (via OpenXR). Testing in the Unity Editor is available through XR Simulation.

Source
Plasticity: What is the pricing model for Plasticity?

Plasticity is a one-time purchase: Indie tier costs $149 and Studio tier is available at a higher price point. A 30-day free trial is available.

Source
Unity AR Foundation: Do I need additional plugins to use AR Foundation?

Yes. AR Foundation is an abstraction layer and requires platform-specific plugins: ARCore XR Plugin for Android and ARKit XR Plugin for iOS. These plugins implement actual AR features using native SDKs.

Source
Plasticity: Does Plasticity integrate with Blender?

Yes. Plasticity includes a Blender Bridge add-on that enables live-linking between Plasticity and Blender, allowing you to preview Plasticity models inside Blender with proper materials and lighting.

Source
Unity AR Foundation: Can I test AR experiences in the Unity Editor?

AR Foundation supports XR Simulation in the Editor for early testing, but accurate AR testing requires real devices because emulators cannot replicate camera and sensor data accurately.

Source
Plasticity: What key features distinguish Plasticity from other CAD tools?

Plasticity features streamlined UI with context-sensitive widgets, chordal fillets, key bindings familiar to Blender users, radial menus, Dimension and Measure commands for absolute constraints, and handles complex Boolean operations on dense geometry.

Source
Unity AR Foundation: Does AR Foundation support web-based AR?

No, AR Foundation does not support WebXR. Unity has stated there are no current plans to add WebXR support to AR Foundation. Web AR requires alternative solutions like 8th Wall.
