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 haven't tried it but can you export it to LandXML and re-import as a design profile? I also don't know if you have to edit the XML file to change it to a design profile prior to import.

DO you want another surface 2" higher or a profile 2 inches higher?

If surface, copy the surface and raise it 2"

If Profile, create an EG profile, copy it and use the editor to raise all pts 2"

I didn't realize that a sampled profile behaves the same as a design profile as far as labeling and editing. So as was suggested, make a copy of the surface profile and raise the vertices by the desired amount using the Profile Edit Geometry tools. You must make the profile static (in profile properties) before you can edit it.

This is how I always get my first run at a design profile when building something like a road where the surface is generally a consistent height above the ground...

Then I can tweak it for variations.

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

Perfect!  Thank you everyone!  It was that Dynamic to Static change I was missing!

Thank you for the info.. This procedure works great for copying an OG profile to create a proposed profile. However, all the vertices are carried from the OG profile to the new proposed profile and I end up with all kinds of labelling on my new profile (see attachment). Is there a way to make it label only the vertical curves? I realize it probably doesn't recognize the vertical curves.

Any idea why I would get a message "no layout profile exists"??? I followed the steps you provided and it works great, when it works! I got it to work in one drawing then tried a few others and keep getting the error message "no layout profile exists". I deleted the profile where I got it to work, went through the steps again but "no layout profile exists"???
