A toy brick macro

[vectronic]

Hello All,

I've been working on this macro for a while with the following aims:

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

The real challenge I gave myself was to use Python scripting with the PartDesign workbench: I wanted to end up with a parametric model fully based on sketches and datum planes.

I've learnt and discovered various things on this journey:

• Multi-File Macro in FreeCAD
• Unicode in FreeCAD
• Reloading FreeCAD Macro Code
• PyCharm for FreeCAD Macro Development
• FreeCAD Part Design Indexes
• Issue with padding up to face

Example images below. Check it out and let me know what you think!

The latest macro code, brief overview and instructions are available at:

The very first v0.1.0 cut is available at:

Wow, a children's dream comes true

Thanks for sharing

Can we have a look to the tree view?

Awesome! I am going to build a WB for building legos, is it ok if i include your script as well?

I am building a parts library for lego pieces.

I like what you have done!

You are absolutely welcome to make use of this if you wish.

nice ! But side holes don't work for me, only side studs.

Sorry, should have pointed to the TODO items from the readme in GitHub:

https://github.com/vectronic/freecad-legify-macros#todo

• Confirm some dimensions
• Pin Rendering
• Technic Hole Rendering
• Support modern tile where the bottom has a small outside pocket (and check if fillet is also required)
• Support rib variation in modern 2x1 tile and 2x1 technic brick with 2 non-offset holes
• Determine a replacement for internal brick ribs if side hole studs exist
• Determine if the inner edge of open studs and hole studs should be filleted

Hoping to tackle the first 3 in the next month or so...

• Technic Hole Rendering

... this —> please

[vectronic]

Initial version of technic holes has been pushed to GitHub, together with some bug fixes and cleanups. Correct measurements for some of the hole features are pending as well as support for axle-shaped holes...

nice ... and what's more, it's completely compatible with the my Assembly Without Solver. I'm thinking about launching a Lego challenge
