I reached a milestone last weekend with a successful render of a brick assembly in FreeCAD.

A bugix version of Legify is available at:

https://github.com/vectronic/freecad-legify-macros/releases/tag/v0.2.2

It provides improvements to measurements and rendering based on using the macro generated parts in Assembly V4 and TechDraw workbenches.

Example TechDraw diagrams for individual parts and assemblies are provided below.

The latest and most likely last version of Legify is available at:

I’ve achieved my goals with this project, which were to:

• Get to grips with FreeCAD and parametric modelling concepts: sketches, constraints, datum planes etc.
• Learn Python and use it for FreeCAD scripting

I’m now moving on to learn about assemblies and technical drawings.

As part of my efforts to accurately model Lego bricks, I need to visualise the finer features of Lego pieces and measure various dimensions accurately.

I’ve been developing a FreeCAD macro for a while with the following aims:

• Get to grips with FreeCAD and parametric modelling concepts: sketches, constraints, datum planes etc.
• Learn Python and use it for FreeCAD scripting

To really push the boundaries, I challenged myself to use Python scripting in conjunction with the PartDesign workbench: I wanted to end up with a parametric model fully based on sketches and datum planes.
