How can I get a slope along my existing surface (between points) in a cross section?
The slope along your existing surface in a cross section can be displayed using Drafting Notes. Select Drafting>Place Cross Section Note>Sections>Right click on Existing and New Note. Expand dialog box, at Computed Values select General>Slope and double click. At Settings>Place Mode select Two Data Points, OK, and then Apply. Select two points on the existing surface for slope.
