Area of inner contour (PRO_CONTOUR_TRAV_INTERNAL)

[MaciejGrodzki]

Hello,

How to fine the area of inner (PRO_CONTOUR_TRAV_INTERNAL) contour of surface? This inner contour has been created by cut feature.

A possible workaround is to convert a surface to a NURB one with ProSurfaceToNURB(...) , apply the inner contour in question from the original surface with ProSurfaceContourArraySet(...) to the new NURB surface while changing contour traversal flag to external.

HIH.

Hello,

Thank you for you answer, I'm still working on it, and but because I'm beginer I have a lot of issues with implemetation. Could you provide more information about your idea?

Thanks in advance.

I see 2 other options, #1 tessellate the contour and calculate the area, or #2 suppress the cut feature, measure, resume, and do a diff of both areas. The last option is handy if you don‘t need to resume a lot of features, and you don‘t want to calc the area by your own algorithm.
