Corridor Rebuild Option

[Anonymous]

Good Morning Everyone,

My question is, why the corridors are asked to rebuild every time I open the drawing?

Although I rebuild the corridors & save the file before closing it.

Do anyone have the idea why this happens?

What service pack? There was a big issue with SP 2 with out of date corridor messages. Even filed a support case for it. SP2 was only out a short time and quickly replaced by 2.1.

If you are sure all drefs are syncing and all your alignments, profiles, surfaces etc. are updated consider switching to "rebuild automatic" option. I used to manually rebuild but switched to automatic in part to this false warning issue in 2012 c3d.

Do you have any surfaces that are data shortcut and being used as targets in the corridor?

We usually have the "Existing Ground" target surface in our survey base dwg data shortcut into our roadway base file. 

This will always show the corridor needs to be rebuilt upon opening the drawing even though nothing has changed.

You can test this by copying the drawing and promote all surfaces rebuild the corridor and save then re-open, it should not be out-of-date, but that is not what you want, just a test method.
