I'm slowly learning my way around (parts of) FreeCAD, but continue to run into things that I don't know how to do. What is the best way to take the attached "frame" and model a corner where two of these sections would come together at a 90 degree angle?

The associated FreeCAD file is attached. I'm running:
Use existing model for BaseFeature of two new bodies. Position as desired, cut(pocket) unwanted overlaping material form both new bodies. You can use a datum plane in one body for that ant then use SubShapeBinder of same datum plane in the other body to cut it accordingly.

Thanks. Do you have any pointers to docs and/or tutorials that would show me how to do this?
Here is a file. I used ShapeBinder instead of SubShapeBinder for the second cut with TraceSupport=true to get a proper plane. Positioning was done by hand.
Your first sketsh is not fully constrained? And instead of that complicated second one you should have used linear pattern.

Thanks. I will take a look. I will also take a look at the linear pattern suggestion.

Thanks again for the pointers on this. Linear pattern was especially useful to what I was doing. I was also unaware of the Base Feature functionality, which seems like it would really be helpful. Unfortunately, I can't seem to make that work. If I select the top-level body and create a new Body, I'm not seeing any base feature. If I try to select a child feature and create a Body, I'm seeing the error "body can't be based on a Partdesign feature". I'm obviously doing something stupid here, but not sure what that might be.
Thanks again for all of the help. I love FreeCAD and this community!

@csetera Select the new body, in its properties click the three dot button at the end ot the BaseFeature property line and select the object to use as BaseFeature from the list.

Thanks. I don't think I would have ever noticed that. Is that new behavior in 0.20 that isn't reflected in the documentation?

Two more possibilities:
1) Select the object you want to use as BaseFeature and create a body
2) For an existing body: In the tree drag the object you want to use as BaseFeature with the mouse on the body
