Hi,
I am stumped on what is happening here.
History:
I developed a simple DD cell with a constrained dimension for Offset. I have used this DD cell for over a year with no issue. When I want to adjust the offset, I would select the Modify Value tool, type in the new value for the offset parameter, and the cell would redraw. Here is an example where I updated the offset from 7.88 to 6.0 using the Modify Value tool:
Now, for some reason, all the cells in my model throw the "Element not valid for tool" when I hover over the constrained dimensions. The cell is still in tact (i.e. it has not been dropped) and I can still adjust the offset via the Modify and Re-solve Constraints tool by clicking and dragging, but the Modify Value tool will no longer work.
I am not aware of any change I explicitly made to my model that would cause this. Further, if I place a new copy of this dynamic cell in my model, it functions as expected. Only the legacy instances are affected.
Any help is very much appreciated.
