It should be noted that 3D modelling software is a subset of 3D computer graphics software used to create 3D models. The individual programs in this set are called modelling applications.

SketchUp (formerly: Google Sketchup) is a 3D modelling program for applications such as architecture, interior design, civil and mechanical engineering, film design, and video game design. There is a free version of SketchUp Make and a paid version with additional features of SketchUp Pro.

There are many 3D modelling programs. Some are freely available, and others are paid.
