Hi,

 

I've got a problem and unfortunately I cannot find any of the lab assistants in my class who knows the answer, although it seems relatively simple, I'm hoping somebody here could help me out. Please see the image below:

I'm wanting to dimension Part 2 according to the second Boss-Extrude on Part 1. I can get the dimensions of Part 1 by double clicking it while creating an equation for a dimension for a line on Part 2, which gives me this:

But, the dimension I placed (see next picture - the dimension itself is an equation with the result being 16mm) on the sketch of the second Boss-Extrude on Part 1 doesn't show up (as you can see from the above picture) for me to select when creating an equation for Part 2:

I know one way around this is when creating the Part2 sketch to select the line with that dimension on (after I've forced the Part1 sketch for the second Boss-Extrude to show) and use the "Convert Entities" button, but it seems I shouldn't have to do that if I can select certain dimensions on Part1 without using that to begin with.

 

I hope I've explained things clearly!

 

Thanks very much for your help,

Alan.
