Adaptive Curtain Panel - Issue constraining in two dimensions

[mjh310]

I am a student working to improve my skills and currently trying to create end panels of a curtain wall so that a circular panel is dimensionally constrained from the bottom and left.  I thought this would be easy, but I can only constrain in in one direction.  If I try constraining in two directions, the geometry fails. I thought this would be easy, but maybe impossible to achieve with a single adaptive panel?

See the sketch below on what I am trying to achieve.  I want to make an adaptive panel that looks like the end panel at the bottom left and replace all the red system panels with that.

Trying to create an end panels with an adaptive component like the one at the lower left.

Create a 4-point adaptive family and constrain the right side with fixed dimensions.

Thanks for the response.  I have no problems constraining it to the right side. My problems start when I try to restrain it from the bottom as well.  I should have included a better sketch of the issue.  the big issue is the end panel at the top left, where the circle is not centered up an down.

Then constrain to the bottom right point.  You can share the family here if you want us to take a look at it.

I uploaded the Family. I've tried several techniques, this one is the latest. It seems to be the right height vertically, but not horizontally.  I get all kinds of crazy behavior when I lock in constraints, so figure I have something fundamentally wrong (still learning).

Try this.  Point #2 is the bottom right corner.

Thanks for the family.  I am having a similar issue with this one, which makes me think I may be making an error when placing it. It seems to work fine when I pick 4 points free-hand, but when I place it referencing four corners of a polygon I get very different results. I attached project file if you want to try placing the family at the corners of the polygons on the left to see if you see the same issue.

I found the problems only occur when using "Place on Face" instead of "Place on Work Plane". so set the Face of the wall to be the work plane, then used "Place on Work Plane" and everything worked great! I will make a new family for the blue panels, constraining to Point 1 instead of Point 2 for those.

You could use the same family, but placing from the other side of the ref plane.

Great idea. Thank you.
