I cannot edit any sketch dimension in a new or old file.
I get a blank or unchanged dialog box when editing, AND two
new dialog boxes come behind. One is related to Shared and the
other is Linked.
I'm using the student design kit 2008-2009. It has been working
fine since January.
Now I cannot create any new sketch or change any sketch dimension
I've done since January. So this is a global issue. How do I get
out of this?
