Dear Russ :

I looked at your model. Couple of observations:

1. Dashed contour lines can cause a little bit of a problem when you cut a cross-section. Solid lines are better. What happens is when we run the internal "fence" command, it sees the gaps in the dashed lines and this can cause it to ignore an elevation point if the cross-section cut line passes over a gap.

2. Even though you have snap set to "off", RiverCAD (and RMS) still read and honor the osnap settings. Type OSNAP at the command prompt and turn "off" all of the object snap settings.

Changing these two items should fix the problem you are experiencing. If you have any additional questions, please contact me again.

Sincerely,
