A patron asked our makerspace to design and CNC mill a replica of the Gemeente-Energiebedrijf sign found all over Amsterdam. They brought us a screenshot of a stock photo and some 6mm thick aluminum to cut it out from. Here's a first rough draft, CAD/CAM in #FreeCAD and milled in a #Snapmaker Artisan. I'm a novice at this stuff, you can probably tell from the results lol, but the next one will (hopefully) be better!

A photo of a shiny metal sign on a faux wood table, taken from directly above. It's vaguely pizza slice shaped, except the part that would be the crust is wider than the rest of the slice. It has a raised outer border, with screw holes at each rounded corner. There are raised letters spelling out "G E B" in the pizza crust area, and below that, the rest of it is taken up by a raised stylized lightning bolt. The very bottom tip seems to be jaggedly broken off.

A photo of a painted metal sign with no background, taken from directly above. It's vaguely pizza slice shaped, except the part that would be the crust is wider than the rest of the slice. It has a grey raised outer border, with rivets at each rounded corner. There are raised orange letters spelling out "G E B" in the pizza crust area, and below that, the rest of it is taken up by a raised stylized orange lightning bolt. The inset area between all the other features is black. All of the paint is very cracked and worn.

After years, we’re still revisiting a new #GSoC proposal to implement #NURBS functions in #Blender, another ambitious project. I’m skeptical: wouldn’t it be better to leverage existing tools like FreeCAD’s #OCCT kernel and wrappers such as PythonOCC, which already provide ready-to-use solutions? A native implementation would require advanced mathematical and programming expertise, which a beginner (still learning C++) would struggle to master in just a few weeks of development. #b3d #CAD

Just out of curiosity, what kind of workflows do you #freecad or other CAD package users have for simple stuff you need to model for 3D printing or CNC'ing?

I start with a crude Post-It note version and try to get all the measurements in that phase, so when I get to the good part, I can just keep on drawing without killing the flow.

A post-it note it a simple drawing of a part, with all the measurements written around it.
