Analyzing an .IGS file

[Grafdude]

I have this .igs file that the customer have provided to me with and I would like to analyze to get the dimensions like radius and distance, but when I analyze a surface for example, it does not give me any dimensions whatsoever, it only tells me its a trimmed nurbs surface with the amount of control points.

 

Also, when I create an edge curve from the models surfaces, the result is a very choppy, faceted arc. I'm really new to model imports in mastercam, any help greatly appreciated!

Yup, best bet, get something better than an iges( I guess it's close enough)

 

I mean you can analyze but as you're finding out, it can be a pain..

 

Best way to think of iges......garbage in, garbage out

Try using Analyze Dynamic.  That can at least give you some info on surface radius (and angle, relative to your construction plane)
