Shapr3D

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.

Moho

Moho is professional 2D animation software focused on drawing, rigging, and animating characters efficiently. It combines vector drawing tools optimized for animation with an advanced 2D rigging system supporting forward and inverse kinematics, letting animators reuse rigged characters across scenes instead of redrawing frame by frame. The software is sold under a perpetual licensing model with no required subscription, and is offered in two editions: Moho Pro for professionals and Moho Debut for hobbyists and first-time animators. It supports physics simulation, distortion meshes, a graph editor for precise timing control, and exports to game engines including Unreal, Unity, and Godot as well as Blender.

Plasticity

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.

FreeCAD

FreeCAD is a free and open-source 3D parametric modeler that allows users to create complex 3D models using a variety of tools and techniques. It is designed to be highly customizable and extensible, with a large community of users and developers contributing to its development.
