Hi
i'm using Civil 3d 2011 & 2012
Existing profile is dynamic but Proposed Profile is Static, When i change the Alignment i must Edit and recalculated
the the Proposed Profile manually , and in a road project when you design the plan and profile of a part of the project, and then your chief ask you to change a small part of plan, you must Shift and move all of Proposed profile manually (because of changes in stations) by changing the station of Proposed profile's PI .
in there a way to make Proposed profile dynamic according to Existing grounde or to shift and move Proposed profile fast ?
If you really think about that, it makes sense to be static. If you change the alignment geometry and the profile has a low point at station Y+##, how would c3d understand where you now want you low point? Since the newY+## has no relation to the old Y+##. The geometric change may preclude the need for a lowpoint at the new sta Y+##.
A good example of that: in one of my recent jobs we were proposing an access road an location A, running west to east. We profiled it, built the corridor with intersections and realized location A was unsuitable so we moved it to location B, about 200 feet to the south running south to north, and 100 feet longer where the topography was completely different. I could never expect the software or want it to maintain the pgl of location A.
Adjusting the pgl was no big deal, and dragging the alignment (and the intersecting alignments) to the new location kept the corridor definition. So tweaking the pgl for 5 minutes everything updated. I didn't have to change any targets
I agree that would be helpfull for those type of minor tweaks. But when I put my try-to-think-like-a-software-code-hat on, I cant see how it can be done
thank you for your answers
you explained exactly what i was looking for
your example was 1000 meters bat imagine that your alignment is 10 km, for every small changes in plan your must
shift and move the Proposed profile in the stations after you change the plan. I change the stations of PVIs to shift and move the Proposed profile after every change in plan. i think this is the fastest way to do that.
thank you again for your time and consideration
"Stretch forward" or "stretch backward" commands should be doable if we can't get a dynamic option. This would move the profile after a certain station by a user-specified distance.
i could not find these commands.
how can i use them and also how can i select multiple PVIs.
i'm using civil 3d 2012
thanks
These are not existing commands, they are on the wishlist.
For the guys getting the big bucks that would be: Stretch.Forward or Stretch.Backwards
i read in a post that you can select and move some PVIs together :
- Select multiple PVI grips using shift+select and move them all appropriately. That's okay for a short distance, but not practical for several miles
but it dos not work

Well, until those 'big buck' guys implement it within C3D, SincpacC3D has done this for quite a while now.... http://www.quuxsoft.com/SincpacC3D_Help/SP_StretchProfile.htm It's not dynamic to the alignment change, but makes editing the profile much easier.
No offense intended good Sir
made a .net program for this and use it everyday when designing a long alignment with couple thousand vertical cuves (couple segments divided).
very simple program. like couple lines in .net that's it. moves vpi both ways. yeah don't expect too much this will be a native feature. but with .net we can just finish the job for autodesk. no need to upgrade after 2013 pretty much lol. 2012 superelevation is funky so 2013 is required.
