Okay, I've never seen this before and I've been using Pro for a decade.
I have a drawing of a casting, which is made with an Inheritance Feature. The part is roughly cylindrical, and when I try to dimension to any shown axis and then an edge I get "Please Select From The Same Model", and the dimension is not created. Now, as much as I can tell, the axis IS from the same model. I used to make a lot of drawings with Inheritance features and never had this issue.
Any idea what is happening here? This is on any drawing I create with an Inhertance.
TIA
ps.I searched the "Knowledge Base" (ha!) and entered the exact phrase "please select from the same model" and got no hits. Nice job, PTC.
The solution was ..... it's a bug.
Fixed in M170.
