Inappropriate "Duplicate Constraint Not Allowed" Error Message?

[bejant]

Sometimes when I delete elements of a sketch I get the following error message:

20151113a-DuplicateConstraintNotAllowed.png (9.11 KiB) Viewed 996 times

So I click the OK button to close the message and depending on the complexity of the sketch, FreeCAD (I suppose) continues to delete the other selected elements of my sketch until the error message might be displayed any number of times again. Each time have to click the OK button to close the error message before FreeCAD can continue deleting the other elements I had already selected.

Because I'm not adding anything (but instead am deleting) it seems to me that the error message should not appear, streamlining the workflow (as was the FreeCAD behavior from some time ago).

Hi Bejant

I tried a few random things in a sketch and not been able to repeat that here. If you could you post a file and some specific instructions, I will try again.

Here's an example:

Edit Sketch, box select the rectangle on the right and everything inside it, and hit the Delete key to display the message. Click Ok, and for me it will pop up again repeatedly.

Hmm... it seems there is an error in that sketch though. I can post more later.

OK , now I get the same behaviour, after clicking OK enough times it does delete the selection but I thought I was going to have to crash FreeCAD for a while.

I get the message very often while deleting only one element.

As a beginner, I was wondering if I had done a bad design, or broken my sketch; after reading this, I understand it's a bug in the app.

Hi DoubleHP, I'm glad you replied because I had forgotten about this issue. To reconfirm the problem I opened the file that I uploaded Nov. 14, 2015 and Sketcher doesn't report any errors either before or after running the Macro_ForceRecompute. In the right rectangle I began deleting the Construction Geometry line segments one at a time beginning with the upper left segment, then proceeding downward, and moving over to the right after after one set of vertical Construction Geometry line segments have been deleted.

After individually deleting Construction Geometry I did a Box Select around the right rectangle and deleted that too.

By looking at the output in the Python Console the error messages happen when Constraints are renumbered:

>>> App.getDocument("_0151114a_DupConstNotAllowed").recompute()

In this use case I think that deleting the Constraints should happen without error messages.
