Editing 3D truss item, can't select the blue lined simplified box shape

[SCParker]

Greetings,

I'm creating a few versions of the Tomcat TC1212-AHB symbol at different angles. I duplicated the symbol and edited to make a 45° version. There is a simplified shape that I cannot seem to select. In Edit 3D mode, the outline of the box is in blue. The second screen shot is what I have at the moment. How do I select the blue line shape to edit?

Thanks, Scott

Thanks Rob.

Hmmm. I had all classes on, etc. 
I had to turn off and on the Simplified class to get it to show. It's working now. Go figure. 

 

Thanks, Scott
