Creating a surface from a surface

i need to create a sub-set surface from my main surface. not sure what the vernacular is for a "subset surface" in c3d but i do have a feature line that bouinds the desired area, but that is as far as i can solve.

 

i did try creating a new surface - pasted the main surface in the edit definition, then deleted triangles until the boundary alighned wiht my featureline.  This seemed to work, but  when i view the properties of the smaller subset suface, it shows a mimum and maximum elevation that is incorrect.

 

any ideas?

Uhh, instead of a feature line you can just make it a 2D polyline and add it as a Boundary.

not sure about the elevation issue - did you add the feature line to the surface definition?


As the previous poster said add a 2d poly as sn outer boundary

Try the Create Cropped Surface command.  The command is located in the expanded Surface Tools ribbon panel on the modify surface or contextual surface ribbon tabs.
