Toposurface Error Message - Revit

Question

When attempting to edit a toposurface in Revit I get the following error message: Contour label doesn’t intersect any contours?

Answer

To work around this issue, you should draw the label line on the toposurface outside the subregion. Then you will either need to move the label line into the subregion or draw a label line that extends past the subregion, and then modify it to fit inside the subregion.
