In the last couple of versions of Fusion I noticed that when I delete an offset constraint, from offset sketch geometry, I am no longer able to use the dimension lines to reference other dimensions with.
Steps to reproduce
1. Create a sketch
2. Create a line/ rectangle
3. Offset the line with a certain distance in positive and negative direction.
4. Delete the offset constraint
5. Edit one of the two dimension lines and try to reference the other dimension line
6. Notice how this is not possible and that when you try to do this in the parameters window, the parameters are either not available or, if they are, they wlll prompt an error message when referenced in another dimension.
Also, notice that when the offset constraint is removed, it will not be replaced with a parallel dimension, but it will be considered as if the line is constrained parallel to the line it was offset from. However, if I remove the dimension, the constraint is also removed.
I often use the offset tool to quickly generate parallel geometry workflow to design based on a central line that is offset (equally) to both sides. Often times, the offset lines will have different lengths and coincident constraints to other sketch geometry.
