This surface was created using the "Create Surface from GIS Data" command and a shapefile with 2ft contours. If I extract the contours from the surface as polylines, create a new surface, and add these polylines to the new surface's definition as contours, the "Number of Points" fields match up. What unnecessary data is C3D grabbing during the "Create Surface from GIS Data" command to create this type of bloating?

I was looking at the wrong value: I was looking at Points under "Surface Properties", but I should have been looking at Points under the Properties palette.</P> Mon, 03 May 2021 16:48:33 GMT https://forums.autodesk.com/t5/civil-3d-forum/mms-file-being-created-for-surfaces-not-meeting-point-threshold/m-p/10287513#M73599 gherrmanRQ549 2021-05-03T16:48:33Z https://forums.autodesk.com/t5/civil-3d-forum/mms-file-being-created-for-surfaces-not-meeting-point-threshold/m-p/10287777#M73600 <P>The question now is why is there a mismatch between these two "Number of Points" fields.
