Parametric offset in sketch breaks when changing dimensions... sometimes. Bug report.

I've attached a simplified part demonstrating a bug in the offset of a sketch. Currently, I'm using parameters for flexibility in design and to illustrate the bug more effectively. I've also tested with direct dimension values and confirmed the same results.


The problem in this parametric model is as follows: when increasing the overall dimension of the base by any amount, everything functions correctly. However, reducing the size of the part causes the parametric offset in the third sketch to break. Notably, the parametric offset in the second sketch functions correctly.


Interestingly, when I decrease the size of the base in very small increments, the parametric offset in the third sketch manages to keep up.

Similar behaviour has been reported previously.

 

Workaround it with thin extrude for the second sketch, will not need the 3rd sketch.

 

Might help…..
