Corridor modeling, sure wish I could drag, drop, trim, edit contours.

I don't suppose there is a way to do 'standard' autocad edits to my corridor surface? I know I can export the surface from the corridor, and then begin trimming and editing, but that saves little if any time over doing my project within Land Desktop. Is the correct procedure for grading the back of my lots along the lines of specifying 'regions' within the model and assigning those regions to attach to another finish grade surface? Also, how can I list my contours? Actually, why aren't my contours just polylines? I understand Autodesk's desire to explore object modeling, and I applaud their efforts. However, autocad is and was a primarily vector modeling system. So by extending functionality by adding on objects, sort of relegates the actual Autocad end to being a glorified viewer. Civil3d at first glance seems great, and from a drafting standpointe apparently it is the best thing in the world, and boy the draftsmen here sure love styles. But, wow, Civil3d sure slows down my design process, a lot. I'm probably the minority in the world, probably noone else that reads this newsgroup likes drawing their own contours. However, I am hoping there is some magic switch I can throw that will let me edit my corridor surface with acad tools (erase, drag and drop, trim, extend, insert vertex, etc, etc). Thanks if anyone knows about it. NUMA

I'm with you on this one. I REALLY NEED to have live contours in live editable poly lines so that I can design the finished surface.

Contours are not the way to design a surface, they're a representation of
the surface.

Would you really want to just put a lipstick on a pig if the underlying
surface data was bad?

I think using contours is a perfectly valid way to include design data in a surface. While I agree that they work poorly to define streets and other "sharp" transitions, used as breaklines, contours are really useful to model smooth transitions, ponds, and other curvy type things. I use 3d plines, and contour plines, to define my design surfaces: It works great.

Now what would be cool is if you could add corridors as objects into a surface to define the road, ditches, or row, and at the same time use breakline and points data, to define the parts of your surface that don’t lend themselves to corridor modeling.

This is already possible right? That is what is happening in the latest
Webcast video where they are combining the intersection of two road
corridors with feature line radiuses.

I like my pigs with a little lipstick too. And nail polish is a plus. Just
no squeeling.

The OP wanted to take the contours generated by a surface, tweak them, and
have those changes reflected back into the surface. _That_ is what I think
is a bad idea, not using contours as original surface data.

Sorry I wasn't clear.

No doubt that drawing contours for the street sections is not practical, where I design with contours is outside the ROW
