sloping contour line in elevation

[Hammer7]

How does one get a grade line to show up in an elevation view when I have an accurate import of existing grade?

 

Training video if possible....?

what does an "accurate import of existing grade" mean. I get accurate grades all the time in the form of ASL numbers along the property lines

 

Then normally I do the math between 2 or more points and adjust the terrain. The math being the distance from grade to top of subfloor, then I double check on the elevation. by measuring from terrain to subfloor, or if I get frustrated draw the line manually using the point markers from the dimension. Its all a PIA, so I'm hoping to see a better response to your question
