LEGO 2 x 4 Brick
Following Yorik teachings about Sketch and Part Design to produce a Lego brick, I used all the measurements (believing it is the real thing) from Christoph Bartnek (March/2019) and design my own 2 x 4 Lego Brick with all the details. I learn how to use of Part Design and Sketch to produce the whole thing, not using at all PART workbench, cut, union and such. The sketch constraints and measurements input, padding and pocket, linear array, make it super easy and perfect fit. That was the real way I wanted to learn how to use FreeCad. Thanks to Yorik dedication in publish such material, and measurements from Bartnek.
