I am using Inroads Suite XM Edition. When I create my cross sections I notice that my proposed surface, in many cases, does not actually meet the existing ground surface like it should. In roadway modeler, the section views all look correct, but in the actual cross sections the end conditions sometimes end short of meeting the existing ground surface and sometimes they go beyond the existing ground surface. This applies in both fill and cut sections, with and without "rounding" option for the cut component. Again, when viewing the sections in roadway modeler, everything looks correct. The "End Condition Properties" in my template has the "End Condition is Infinite" option checked on as well. Can someone tell me how to fix this issue?
If you are not cutting cross sections at points that match template drops, then gaps can easily happen.
Also, there is a method of plotting surfaces in cross sections that only draws segments between features. I've seen it happen that the last segment of a surface is not drawn because there was no linear feature at the tie in - only random points.

In Surface Properties>Advanced look at "Use Features Only" x-section setting to see how it may help.
Creating Transverse features in you roadway designer created surface may help as it forces DTM triangulation to honor design template and you won't get any triangles crossing these breaklines.
caddcop is correct. If you want to cut cross sections every 25' but do a template drop every 50' InRoads interprates between the 50' space to come up with a cross section. And you get slope intercepts that don't hit existing ground. My rule of thumb is a template drop at least 1/2 the length of what I expect to cut cross section sheets at.
I understand all of the comments and explanations. What has been said does make sense. I will drop my templates at shorter intervals to see if this makes a difference. In the past I have been reluctant to drop templates to frequently due to the time it takes to crank through everything, but in this case it may make sense to do this. Thank you everyone for your support, it is greatly appreciated.
