Bug. Constraints fail with projected curves in the sketch.

What I've found is constraints fail on offset curves if there's a projected curve in the sketch, the projected curve is totally independent of the offset curve or the curve\line being added. If you delete the projected curve auto generation of constraints works again.

Thanks for reporting this, Mark - Jeff chimed in on the thread you linked to

Thanks Brian, I just want to confirm @jeff_strater has watched this screencast as it demonstrates the problem far more clearly than the one in the other post.

Wow...  Thanks for making sure I paid attention to this.  This was very good detective work, @HughesTooling.  You should come work for us...

Pretty amazing, knowing what I know about the code, that this exists, and to be honest, I had to try it myself to prove it to myself.  But, it is true.  Just the mere presence of that projected geometry, even if it is not related to the geometry involved in the constraints being inferred, makes the inference fail to take.

I have filed this as FUS-26872.  I will raise awareness of this ASAP.

Thanks again for the detective work.  This bug has been fixed (thanks, @jiang_peng!).  I don't know exactly when it will work its way through the pipeline to get to an update, but we are pushing to get it included in the next one.

Thanks Jeff,

It bugged me that it worked some of the time, I just had to figure it out.
