I have a tube with multiple sections and I would like to calculate each section's surface area automatcially.
Problem: when I pass the faces of the tube, NX also reports the are of the faces which are not filled.
Example: I have a tube with 2 devided sectional tubes as shown in the picture. I only want to pass face A and face B of the sectional tube #1 and sectional tube # 2 into my program. However, I do not how to filter face A1, A2, B1, and B2 (end of sectional tube #2)
