If you're trying to constrain accurate 8020 profiles there is only a tiny flat section on the surface. If you are using flush constraints this is the only surface that will work as expected.

You often have to zoom in quite a bit for the flat strip to show up. Once you learn how to do this it will become second nature.

Also beware that the extrusions are 7 mil smaller their nominal length. You might have to use an offset to account for this.

80/20 has a 4 degree angle to make a vibration free connection. There is nothing stopping you from modifying the profile to be more square and easier to work with for your model.
