Creating Surface from 3d Polyline

I wish to create a Surface from the 3D Polylines that already exist in a drawing that I am working on. We do not have a point file for this area since we were never given one and the only thing we have with surface elevation is the drawing with 3D polyline line on it. The drawing does have point data in it but the points appear to have been exploded so they are no longer together. I need this existing ground surface so that I can get the get elevations at the place.

if someone knows where to look in that book that would be helpful to know too.
am attaching the drawing

Yoks,
I don't think you can create a usable surface. Those 2D Polylines are at insane elevations.

Hi,

 

I post some workflow in video bellow and I hope that will solve your issue!

You only have one line at elevation. You would need a minimum of two to create a Surface. Maybe if you describe what your trying to do. Other than trying to create a Surface. We could be of more help.

Maybe someone forgot to share this tip. 🙂

 

When you get polylines with elevations as seen the the original file posted (MOD-2400-3300-R91).dwg they can be fixed in less than a minute.

 

Select them and use Convert 2D to 3D Polylines in the Design panel dropdown of the Modify tab.

The polylines may have been created by a Bentley product.
