Created Surface from polyline contours

[Tom.Weinstein.137333]

I created an existing surface from some contours in order to fully use C3D's surface functionality. After creating the surface, I want to delete the contours I used to create the surface because they are redundit in a sense. Problem is, if I erase them, then C3D wants me to update the surface and everything disappears. Is there a way to remove the polylines I used to create the surface without destroying the new surface?

uh yes, you can create a "snapshot" of the surface(right click on surface name in prospector, create snapshot), which i beleive freezes the definition, then you can remove the plines. Of course, if you ever need to change the surface, then you have to add back the definition objects.

Another way to do it would be to add points along the contours and then use those points as your surface data and delete the contours after rebuilding the surface using the point group you created.

I think the safest way to get a "clean" surface without any source definition, is:

1] _LANDXMLOUT
2] erase the contours and the existing surface
3] _LANDXMLIN

BRILLIANT! Great suggestion, thanks.
