Centerline and Profiles

[don poole pls]

I am having the most difficult time creating centerlines and profiles from
either the grid file, or the existing topographic details. I can create the
centerline, but contrary to the manual I do not have an option for
"elevating" the polyline under my 'design' options. If I create a 3d
polyline then I can't fillet it to create arc's, and when I simply re-do a
3d polyline over an existing 2d polyline then the profile will NOT ignore 0
elevations.

I am wondering if I am simply missing something (such as why does the manual
tell me I can "elevate" a 2d polyline but the command doesn't exist in my
program.) or is there some sort of bug in the program? Or simply operator
error?

I am not succeeding in creating a simple road plan because of this problem.

I don't have a menu in front of me, but it sounds like you are talking
about "2D to 3D Polyline by Surface Model"

If I create a 3d
polyline then I can't fillet it to create arc's,

True. 3D Polylines cannot contain arcs.

your demands
