Conflict with contour lines and other entities

The first phase of our floodplain evaluation was the original conditions. For the second phase, we are evaluating the floodplain with a new golf course built adjacent to the river. It is too big to draw as an encroachment, so we are doing it as a second project (separate file). In order to cut the cross sections in the same places, I X-referenced the first floodplain drawing into the second, turning off all layers except for the original cross sections (Boss Topocut), then cut cross sections along the same lines. I am cutting into contour lines with elevations (z-values). This works pretty well, except that RMS does not recognize an elevation layer right next to the original cross section; I have to move a short distance away from the original cross section before I can grab a contour elevation line.

Have you encountered this before? Do you have any suggestions? This method will work; however, suggestions are welcome.

Dear Merle :

You are running into a restriction from the CAD engine. We are inquiring the drawing file for drawing entities on the specified elevation layers, but the CAD engine is not returning a selection set with entities since the previous cross-section cut lines are restricting the new cross-section cuts.

However, there are a couple of tricks you can use:

1. There is a "Recut Topo" command in the Input | Ground Geometry menu. This command allows you to have both existing and proposed topo in your drawing file, and have RiverCAD / RMS then create a new cross-section by simply recutting the existing cross-section on the new topo data.

2. If you want to manually recut the cross-sections, then simply offset the previous cross-section cuts by a small amount (let's say 5 to 10 feet) and then cut your new cross-sections parallel to the previous cross-section cut lines.

If you have any additional questions or need any further information, please contact me again.

Sincerely,
