FreeCAD

FreeCAD is a versatile program for parametric 3D modeling. As well as engineering tasks related to it, it was designed from the beginning for the purpose of completing engineering tasks at any complexity. A wide toolkit makes it possible to create 3D models from all types of data. Users of FreeCad are able to separate the program's toolkit into several workspaces (profiles). In accordance with the tasks, the user fills out the profile with the tools necessary to complete the task. The panel contains no additional features and none of the user's tools. Several of the workplace types also come with several readily available tools. experienced user interface for experienced 3D ee to experienced 3D-developers. For the first time the program is started in the "complete workbench" mode (full workbench)

FreeCAD has a set of tools worthy of any 3D model development environment. There is no lack of standardization across object control capabilities (zoom, plane shift, rotation). (bars, curves, arcs, shapes in the shape of curves, circles, and arcs, with s and dimension lines). A notable feature is that there are so many various models of primitive things and systems that deal with changes in objects pertaining to space (cutting off, fusion, extraction, pulling out, etc.). support of scripts. By going to your built-in Python console, any element of the program can be accessed and made to changes.
