FreeCAD

Architects and engineers draw models before implementing the actual project. FreeCAD software allows you to create and draw geometric concepts and develop 2D and 3D animations of other complex shapes on the computer. It runs on a comprehensive graphical user interface (GUI) platform that allows you to sketch and draw 2D and 3D shapes and objects for graphical representation. It also runs in command mode, which remotely uses a GUI to continue drawing the animation. It uses geometric concepts to create components from other programs. It supports the creation and modification of parameters such as rotation, translation, matrices, transformation, zoom, shape transformation and others. The interface has a feature-rich program that allows you to develop multiple projects by importing and exporting projects such as MCAD, PLM, CAX, CAE and 3D CAD. It supports major file formats such as SVG, BMG, JPG and SVG, among others. It also supports 2D animation with the following additional functions: rotation, translation, editing, zoom function and delete function. And also 3D objects. The software can use Boolean functions, merging and cutting options. Geometric concepts can be edited in the Python console in a built-in interface to support graphical modeling of a complex part of an object's structure. It's a simple interface, but it requires a bit of graphics integration knowledge to create high-quality 2D and 3D animations. FreeCAD is licensed as free software for PC or laptop running 32-bit and 64-bit Windows operating system. It is categorized under Architecture/CAD and is available as a free download for all software users.
