Another constraint bug - coincident constraints not being obeyed

[robduarte]

As I said earlier this week, I'm trying to show reproducible examples of constraint issues. The previous one was verified as a bug - please let me know if this is also a bug or if I'm missing something:

Thanks!

Thank you @robduarte for brining this to our attention.  We are looking into it and will follow up with what we find.

Thank you,

@robduarte,

When an endpoint is constrained to a line, the "line" in infinite.   Meaning when you drag it, it will not stop at the endpoints.  Collinear constraints can only be created between two lines, you cannot have a collinear constraint between a point and a line. This is as designed and considered the standard across CAD packages. I would suggest adding a dimension to the point if you do not want it to move when you drag.  In your video when dragging the sketch, you see the sketch flip, that is a bug and a known issue.  This is due to the speed of the drag affecting the compute and we are working towards a solution.

What is shown here is correct.

Thanks for the clarification. I'm not dealing with colinear constraints but the idea that coincident constraints are constrained to a line and not a line segment was something I didn't know about. The flipping was a separate problem that I was experiencing - glad you're working on it.
