3D modeling and CAD apps

3D modeling and CAD software builds digital models of objects, either as precise engineering geometry or as freeform meshes for rendering, games and printing. Computer-aided design focuses on exact dimensions and constraints, while 3D creation tools focus on shape, texture and animation.

The apps here span that range: parametric modelers for mechanical parts, a modeler driven by code, 2D drafting tools for technical drawings, an electronics design suite, a mesh processing tool and full 3D creation suites. Consider whether you need precise dimensions or artistic freedom, which file formats you exchange, and whether your models end up on screen, on paper or on a 3D printer.
