Create proposed profile from surface profile

[TonyLeggieri3279]

We have an engineer who is taking an existing surface and wants to show a proposed road 2" higher than existing.

I told him to simply adjust his assembly for his corridor to account for the 2" difference, but the County agency needs to see a profile.

My questions:

1) Is there a way to easily copy a profile made from a surface and "convert" it to a proposed profile?  If we copy and explode, it turns into hundreds (thousands?) of tiny pline segments and it would be a mess to convert all those to a profile 1 by 1.  If we make the corridor, and choose "profile from corridor", we do not have an option that could be used to represent the centerline. 

2) Other than loss of dynamic updating), would it make sense to adjust the assembly so the top surface would be accurate, then copy the profile, explode the copy to a block and simply shift that (as essentially basic linework)?

Any help/opinions would be appreciated.  Thanks.

I think this may be the solution to my issue. Another drafter has created surface profiles and now we want the road grades to change but cant edit anything. Can you explain these steps in a bit more detail taking into account my surface profiles are already created?

Here is a link to my query I posted and the couple replies I did get: http://forums.autodesk.com/t5/autocad-civil-3d-general/editing-profiles-pi-s-amp-vpi-s/m-p/6431868#M...

Hi Jason

What part is unclear to you?

To convert a surface profile into a layout profile do the following:

1. create your surface profile and view (call it eg temp) and make it static

2. create a layout profile say (fg(x))

3. draw an arbitraryl line (doesn't matter how long or where), exit the profile layout tool

4. edit eg temp geometry and press copy

5. select overwrite existing profile and select fg(x) from the pop down

6. go back to eg temp and make it dynami again is needed

in some cases it my be prudent to simply draw a new layout profile and in your other post it sounds like this is what you have done. The only step after that is to go into the corridor parameters and change the profile assigned the the baseline in question.

Alright, Corridors are set up but they have no surfaces or baselines...(see attached)

Thanks,

Jason

Also, do I want to delete the surface profiles now that I have created profiles from layout?

[Joe-Bouza]

Show me The parameter tab. Even still the lack of corridor surface points to feature line grading... can you post the drawing? Without looking in it I'mm only guessing

is there a way to convert a superimposed surface profile to a layout profile? Thanks.

[Joe-Bouza]

Probably not . Have you tried making it static and copy to layout as I describe for the surface profile

One normally traces the surface profile as design profiles are usually "cleaner" than EG.

yes, i did, the superimposed profile keeps as "dynamic" even after the original surface profile has been set to static.

understood, i am using the superimposed profile as my corridor target profile for the lanes and the gutter lines, in some local area, i have to do some adjustment to smooth out my design, i wish i can use the superimposed profile as my start point, for those area i don't need to adjust, i will just leave the profile as is.

the only way to convert superimposed profile to layout profile is to explode the the superimposed profile to CAD entities (lines), and then re-define a layout profile using the CAD entities. I tested this method this morning, it worked.

Brutal. Excellent Solution! It works Great!

Great advice Master, congratulations
