There must be a solution to this issue.
I need to be able to unselect all the surfaces when creating sample line groups! And then select only the two that I need.
Does any one have a solution?
I've been told to leave them all selected and chosen the correct surface when assigning materials.
This is not a good solutions when I have 30 surfaces. It only slows down the processing when creating the sample lines.
With an unselect surface I would save around 6000 clicks on my current project. Time is money boys!
How do we get through to Autodesk?
For the reply above I forgot to mention the version I'm using.

I have the same question. From trial and error the solution I am using is highlight all the surfaces, unselect, then select the section I want. At first I just left them all there but noticed it took longer to form each sample line; from 3 to 5 minutes - with 77 to make that is nearly 8 hours!
The trick is to select all the surfaces except for one, else you cannot unselect and have to start over.
