It could also be that a 'hide' boundary is applied to the surface. If this
is the case remove the boundary & apply a mask. A mask will still show the
data in profile.

I replied to this earlier, but it isn't showing up for some reason....

Create a new surface profile for 25+00 to 26+00.

When you create a surface profile, and specify the stations to use, you
cannot later change the sampled stations.

You most certainly can change the sampled stations in a surface profile. Just grip edit the alignment to make it longer and the corresponding sampled EG profile will increase proportionally. (Providing, of course, there exists viable EG surface under the increased alignment length, as pointed out by others here.)

Sorry, but that ONLY works when you sample the entire alignment to begin
with. When you specify a station range to sample, as the OP noted was done,
you cannot later change it.

Jeff: You are right and I stand corrected. I missed that the OP had only sampled part of the alignment at the start. To be honest, I have never sampled less than the full alignment, feeling like I can size the PV accordingly if I need less.

[#6]

I have seen multiple cases in C3D 2013, where the full alignment was sampled, but yet stretching the alignment after the EG profiles are drawn - does not automatically stretch the EG profiles.

The fix for this is to go into Profile Properties, on the Profile Data tab, change the Update Mode to Static, press Apply, then change it back to Dynamic and press Apply.

Having said that, I just created an alignment and profile in a dummy drawing and it works like you would expect, maning that you stretch the alignment, and the EG profiles stretch. So I can't recreate the problem on demand, but I know I have seen it on multiple occasions.

Thanks for the update on this Randy.

Could this be one of those issues that only appears when you open an previous version file on 2013?

That is very possible. I don't think the drawing with the problem was started in an earlier version --- but with cut+paste, etc., you never know what strange things can get carried over from DWG to DWG....
