I've noticed this before, but in some instances, virtual sharps do not stay in place.  This seems to be an issue when you create a sharp at an intersection between two lines where one or more of the entities is a spline.  Regardless of the "intersection" constraint, the point can be dragged anywhere on the screen.  Even if one of the entities is a straight line, the sharp will not stay attached to it.  The software lets you create the virtual sharp (by clicking both edges and selecting the "point" button).  If attaching to a spline is not allowed, shouldn't SW not allow you to create it??

I'm currently working in SW2014.  I tried it quickly in SW 2016, and there seems to be the same issue.

Anyone else seeing this?  Is there a solution other than "fixing" the point in space?  Or is this another "bug" in the software?

Thanks!
