Change pipe profile from outvert to invert

[qchenTPPXV]

Good day,

A pressure pipe was create on a plan view and a pipe profile was created as below. The pipe's profile is the outvert of the pipe. Is there a way to change it to the invert of the pipe as yellow line below? The consultant provides invert level, it would be easier if I could use the profile in invert to adjust the pipe.

Hello @qchenTPPXV ! The pipe run profile is always at the top. What you can do is draw the profile you got from the consultant and then knowing the external diameter of your pipe you can copy the invert profile and offset it of the external diameter value. Then you can update the profile and tell it to follow the offset profile. 

What kind of data you got from the consultant: 3D polyline, points ?
