Wiki says: FreeCAD is a free and open-source (under the LGPLv2+ license) general-purpose parametric 3D computer-aided design (CAD) modeler and a building information modeling (BIM) software with finite element method (FEM) support.[2] FreeCAD is intended for mechanical engineering product design but also expands to a wider range of uses around engineering, such as architecture or electrical engineering. Because of the free and open-source nature of the software, users can extend the functionality of the software using the Python programming language.

Elevator component

Submitted by Stopka on Sun, 05/02/2021 - 23:16

I was asked to print a replacement for a broken part of an elevator. I don't know where exactly this piece fits on actual elevator, but it seems to be a cover of an emergency telephone speaker.

Originally I wanted to do it my traditional way. First scan the piece using ordinary 2D scanner. Then trace outlines in Inkcape to get vector paths. Export paths to Openscad and there use several extrusions, differences, joins and other operations to create a model.
