Sketch not applied to part body

Post by csetera »

I'm struggling to consistently get my Part Design bodies and associated sketches set up properly. I'm not sure what I'm doing wrong when creating the part and, even more importantly, how to fix the situation. The sketch looks like this:
sketch.png

The resulting body:

What can I do to salvage this sketch? Any idea what I'm doing when I set up the original part and sketch so I can try to avoid this situation in the future? The design is attached.

Thanks,
Craig

The first thing to do is DON'T mix Part and Part Design workbenches until you understand the rules of how to do so.

Start in one or the other and learn it, then move to the other.

I can't really grok what you want to accomplish with this model. You currently have 5 separate solids. Well, actually 4, because the ones highlighed below are a single Part workbench solid...

Construction mode edges are not used in a Pad.

I'm trying to design and test in smaller pieces that I'm testing on my 3d printer. Whether this is the best workflow, I don't know. I'm trying to design one side of a case at a time. I'm testing horizontal "slices" of those walls for fit before trying to put all of the pieces together into a final case design.

Ignoring whether or not I'm using the best workflow, the issue I have right now is the blank "wall". The other parts were intentionally hidden while I was working on the wall and can be safely ignored at this point. For what it is worth, I do believe I understand conceptually how these different tools are supposed to work together. The primary issue right now is around a part design workflow versus the use of those designs.

I'm only using those edges for other constraints. The rectangles are what I expect to be cut out of the pad.

The only rectangle I see that is not construction mode is the outer rectangle.

Then I simply do not not understand you question. If you convert the holes to geometry rather than reference geometry (and get rid of the 0mm dimensional constraints), it works as expected.

Ahh crap. I know what happened. I switched to construction geometry to set the initial horizontal lines and then forgot to switch back. So stupid! While I'm slowly getting better with FreeCAD, I'm still clearly a newbie. Thank you for pointing me in the right direction.

Thanks... I didn't realize I had not toggled back from construction geometry. (see my other response in the thread)

If you hides the pad and show the sketch (space bar), you see the result sketch : a simple rectangle.
