Use Sketch from file A to add features to part in file B

Post by ozindfw »

I'm a complete newbie to FreeCAD. I'd rather RTFM, but I can't figure out which FM to R. I think I'm missing something relating to states transitioning from a sketch to a part body.

I have a part that is essentially an 1/8" plate, that I need to bolt some purchased parts to. I have the plate in a file created with sketcher and extruded with PartDesign (file B.) I have a sketch of the hole pattern for the part to be bolted in a separate file (A.) I'd like to be able to use it to extrude holes n the plate. I can't figure out how to accomplish this. I have several parts with different hole patterns that will be placed on the plate.

I've tried making the hole pattern sketch a part that I could use to 'punch' holes in the plate, but I can't seem to make a body from them. Not really surprising, but it was a shot in the dark.

I'd also like to be able to carry some documentation along like the part outlines for the parts added to the plate. While I know this isn't correct, I currently have these as construction lines in the sketch. Is there a way to carry this information along without making them a physical feature of the part?

I've attached the baseplate file and an example part.

Thanks,

Oz (in DFW)

That jut might do it. I need to read it when I'm more awake tomorrow.

Regardless, thanks.
