Re: 100 cad exercises

Yeah, many if not most of these drawings are riddled with errors, missing dimensions and conflicting info. Here's an idea: create our own CAD exercises, showcasing TechDraw along the way. The examples we produce could be collated into a single PDF shared on the forum or the wiki... and the FreeCAD ...

Re: Help with milling all the way to edge of part

It won't be automatic but you can probably get what you want by using the dogbone dressup on your profile operation.

You might have to apply multiple dressups and configure them differently to get the correct clearing for all the corners but it should be possible.

Re: 100 cad exercises

Here it is. You heard it here first: 'FreeCAD Golf' I'm imagining an add-on which adds a button to a toolbar that when pressed starts a counter of transactions or perhaps just keeps track of the python commands. When pressed again, it ends the count, reports the number and copies the log to the clip...

intersect bsplinesurface and line [solved]

I have a bsplinesurface that I've constructed from a set of points. I also have a point inside the XY bounds of the surface and I want to find the corresponding Z coordinate on the surface.

If I construct a line that runs through X,Y,0 and X,Y,1, Can I find where that line intersects the surface?

Re: V-Carving

Can't do it yet but have some plans. Now that openvoronoi has be re-licensed as lgpl, v-carving is even more do-able.

Just needs someone to jump in and make it happen. :D

Re: $1m to pay open source maintainers on Tidelift

It's an interesting idea but I think they ignored the hardest part: Most open-source projects (including FreeCAD) don't have a legal entity that could receive payment. So payment can only be made to individuals. But there's no mechanism to decide which individuals should get paid or how much of the ...

Re: Adaptive Path/CAM Operation

Very Nice! Huge improvement for me. Even on old-busted computer, less than 30 seconds to build the path. Thank you!
