another profile/ profile view question in civil 3D

[youngEIT]

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.

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.

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!
