FreeCAD Part Scripting in Python Episode 025

Description: Design an enclosure for lighting controller. Software toolchain includes: Notepad++, FreeCAD, CURA, and Repetier-Server controlling a MakerGear M2e. FreeCAD has a dimensional-accurate parametric modeler driven by python code which is helpful for iterative design and modifications. We walk through the python code to design our FreeCAD 3D model starting with simple python statements and evolving to a scalable, repeatable structure using a wide range of Python capabilities such as lists, dictionaries, for-loops, if-then-else conditional statements, custom classes and even Bezier curves. #led #circuit #digitalelectronics
