FreeCAD is a general-purpose parametric 3D computer-aided design (CAD) modeler and a building information modeling (BIM) software application with finite element method (FEM) support. [4] It is intended for mechanical engineering product design but also expands to a wider range of uses around engineering, such as architecture or electrical ...
SolveSpace is a free and open-source 2D/3D constraint-based parametric computer-aided design (CAD) software that supports basic 2D and 3D constructive solid geometry modeling. It is a constraint-based parametric modeler with simple mechanical simulation capabilities. Version 2.1 and onward runs on Windows, Linux and macOS.
One goal of CAD is to allow quicker iterations in the design process; [9] another is to enable smoothly transitioning to the CAM stage. [10] Although manually created drawings historically facilitated "a designer's goal of displaying an idea," [11] it did not result in a machine-readable result that could be modified and subsequently be used to directly build a prototype. [12]
] CAM is a subsequent computer-aided process after computer-aided design (CAD) and sometimes computer-aided engineering (CAE), as the model generated in CAD and verified in CAE can be input into CAM software, which then controls the machine tool. CAM is used in many schools alongside CAD to create objects.

CAD/CAM systems use primarily two types of surfaces: Regular (or canonical) surfaces include surfaces of revolution such as cylinders, cones, spheres, and tori, and ruled surfaces (linear in one direction) such as surfaces of extrusion. Freeform surfaces (usually NURBS) allow more complex shapes to be represented via freeform surface modeling. [1]
