I have three workplanes. All three were created the same way (offsetting an existing workplane). I want to change the offset dimension. I can on one of the planes, but on the other two, I have to "Redefine Feature". There is no Edit dimension available in the menu.
One plane like this:
Two planes like this:
Why is it different?
Have you tried double clicking on the plane to see if it brings up the edit dialog?
Double clicking on the plane does nothing. I know it should show me the dimension so I can edit it, but it doesnt. I have to "redefine" the workplane.
After I redefine them, then I can double click the plane or right-click and choose "edit dim".
I come across parts all the time like this... its not just this one.
With 2013 they added the Edit Dimension to the mini toolbar pop up in canvas. Click on the offset WP in the graphics screen and see if you have the little toolbar to choose Edit Dimension.
