    Sample multiple Surface Profiles at once

    Since references sometimes change and there's no way to change the pointer
    easily, it would be nice if we could pick a surface, and then sample
    profiles for all alignments, or have a checkbox list that would let us
    sample them all.

    We're working on a storm plan, and when the paving corridor changes, that
    means my FG surface changes. At that point, I kill the reference in my Storm
    Sewer plan, and create a new one. With a small site like we're on, I have 21
    alignments that I then have to resample.

    It's not the end of the world, but it would be a nice efficiency change.

    Maybe something to hack out in VBA real quickly?

    I'm wondering. If you specify the profiles to update dynamically with the
    surfaces, why would you need to resample them when the surface changes?

    Because we're using reference surfaces. In this case, a reference to a
    Proposed Grade surface that was built from a Corridor, Points, and
    Breaklines.

    Since C3D surfaces cannot directly reference Corridors surfaces, you have to
    export that surface. This data is added by adding points to a new surface.
    When you do that, it breaks the link between profiles and the surface. We
    then add points and breaklines to define typical lot grading. We make a
    Shortcut to this surface. If (when) the paving profiles change, that means
    the underlying corridor to my PG surf is incorrect, and the surface is wrong
    in my shortcuts.

    In our search, we found no way to remove the data from the 1st Corridor
    iteration from the PG surface, so we have to create a new surface, then add
    points and pads again. This new surface is then added to the shortcut menu.

    The problem with this approach is that other dwgs that use the shortcut to
    generate profile information are now linked to a bad surface. There's no
    easy way to repath the XML shortcuts to the new surface, so we just erase
    the Reference surface, and create a new one from the new surface. This
    requires resampling.

    Easy, right? I've gotten the VBA together to sample all the alignments in a
    site to a selected surface, so it's not the end of the world, but it would
    be nice if it was built in.

    Shoot! That IS a bit of a pain. Good luck :smileyhappy:

    I'm just getting started in C3D, so forgive me if my question is too simplistic, but do the shortcuts point to a specific surface (i.e. object ID) or to a specific surface name? If it's the name, could you just update the names so your revised surface is named what the old one was and the shortcuts point to that now?

    It's both actually IIRC.

    I'll let one of the 'deskers answer it. You might be right about the
    renaming thing...
