another profile/ profile view question in civil 3D

another profile/ profile view question in civil 3D

another profile/ profile view question in civil 3D

(OP)
i have a proposed profile that starts at 0+00, cuts down, then comes back up and hits existing at 5+00, then rides existing till 7+00, cuts down again, then finally meets the existing back at the end of the alignment (15+00). in my profile view, i want the existing profile to show for the entire alignment length (which is easy), but, for proposed, i want to show from   0+00 to 5+00, then again from 7+00 to 15+00. is there a way to do that in civil 3D? any suggestion appreciated.

RE: another profile/ profile view question in civil 3D

You can delete out sections of your proposed profile (maybe make a copy of it?), but I think that they are sections between PVIs rather than pieces of curves or tangents.  There's nothing stopping you putting an extra PVI into a tangent, but you'd be out of luck on a curve.

The other alternative is to make a copy of the proposed profile and then explode it into lines and arcs, but of course then you lose the intelligence of it.

RE: another profile/ profile view question in civil 3D

for the first part, my proposed profile is the sampling of the same alignment over my proposed grading (contour) lines; so, no changes allowed in the profile view. only changes allowed is changing my contour lines.
for the second part, i tried exploding. when i explode, the profile view stays, but the actual profile lines disappear!so forget lines and arcs, you would end up with only the view grid. i tried sampling between the stations; works fine for 0+00 to 5+00. but when i try to create the second part of it from 7+00 to 15+00, for some strange reason, it will create the profile, but will have almost a straight line link between 7+00 and 0+00!
