This worked to allow me to create and print the part-pocket I needed, but I know there has to be a much more expedient way to do this rather than by brute force and manual pick & choose... Still hoping someone can load the stl and/or step I posted and let me know what the modified procedure would be... Thanks for any guidance.
Congratulation!
BTW I can't get your step file, error 404. Yesterday the same, so I was not able to have a look.
OK, then maybe I'm approaching things wrong. If I create a cube, move the item in the step file onto the cube and into it slightly, and with the cube, I attempt to cut the step file item out of the cube (effectively wanting to create a "mold" image of the item on the cube) - it won't let me.
If I select the imported step object and select it and try to perform a "union" on it, it says "Illegal storage access! Please save your work under a new file name and restart the application"
If I import the step file, and (from the Part workbench) I "Create shape from Mesh", it does that OK (the step object now has hundreds of little lines all over it... but that appears to be correct)
If I then select the newly created shape, and attempt to "Convert to solid", I get the error "Shape is not a shell".
I need to be able to do - whatever it is - so I can use these board stls or steps to be able to cut out their shapes from other simple objects like cubes, etc.
I don't need to do much to the boards themselves (the items in the step files) - I just need to use those to cut their impressions out of other objects.
This step file contains many solids. If you use Part Check geometry on any single solid it is good. But, if you Check geo on the Std_Part container (the yellow icon) that contains them all, there are a mess of overlapping faces and edges. Also, a lot of bad curves. The overlaps are probably where the various components touch the pads on the board. This means the conversion to mesh is not going to produce a valid mesh that can be converted to a shape and then to a solid.
Somebody else may have some ideas. I'll have a look in the morning to see if I can get something usable using Blender to do a shrink wrap around it.
(The usual tricks like loading it into VariCAD and saving didn't work for me...)
Star Trek II: The Wrath of Khan: Spock: "...His pattern indicates two-dimensional thinking."
That explains much, thank you. Shrink-wrapping sounds like a hopeful idea. I'll look into Blender in the morning, in case it turns out that works. Is that a separate package or part of FreeCAD?
