Volume-point profile curves
Edit X and Y cross-section curves for a volume point and optionally link the axes.
ProfileThe Curves tab in Volume points edits the X and Y cross-sections of a point’s influence. These are surface-shaping controls, separate from the terrain Analyze → Profile tool, which measures an existing surface.
Open the point curves
Enter Volume points, select a point and open Curves. The panel shows X Profile and Y Profile. If no point is selected, the first available point supplies the displayed profiles. Add a point first if the list is empty.
Adjust the curve
Select and move a curve point or its curve handles to reshape that cross-section. Inspect the surface while editing. The chart represents physical profile coordinates, including negative heights; it is not a set of North/East/South/West edge profiles.
Link the axes when appropriate
Turn on Link axes when you want edits applied to both cross-sections. Leave it off to shape X and Y independently. Check the model after changing a curve, especially when other points overlap.
Finish or undo
A drag previews while you move and records the completed change when released. Use Undo to reverse it. Done leaves Volume points. A terrain analysis profile remains a separate object and is not edited through these curves.
