Select only Non-Vertical and Non-Horizontal Surfaces

[Niezingerly]

Good Morning all...

 

Would there be a way, with whatever method (VB, .NET, chook., etc...) to select all Non-Horizontal and all Non-Vertical surfaces?

 

This would be in relationship to the TOP view...

 

Essentially, I want to select any "drafted" surfaces...

 

I have (4) different models, and there are from 1600 to 3500 surfaces on each, and for CAM programming I need to separate out the differing surfaces...

 

 

Windowing works to a degree, but the form of the model doesn't always lend it's self to "easy" selection through Windowing, and I end up having to go back and re-pick the surfaces that Windwoing "missed"

 

 

So, yes, I have heard the argument before that I should just be using Solids, boundaries, etc, to achieve "similar" results, but that is not the way I want to do it, so let's not go there for now...

 

 

I am in X3, 64 bit.

 

I have access to X5, where in I saw that I can "color" any drafted surfaces (analysis?), but it seems to not actually "select" the drafted surfaces, so that I could manipulate the levels of the differing surfaces...

 

Anyhow, thanks in advance
