AutoCAD Civil 3D

[#1]

I am in the process of creating the cross section sheets and including them to an existing sheet set manager.  When I try to create them I get an error saying "Sheet Set not created" which is odd because I selected add to existing ssm.  If I save and exit out of the drawing and then get back into it, the sheets are created correctly in my layout tabs, but aren't added to my ssm.  Any help or information would be appreciated.  Thanks!

We're running 2012 C3d sp 2.1 and just got this message for first time today.

Same scenario, chose "add to an existing sheet set" & browsed to the sheet set location which prompted error.

Other weird thing is you don't immediately see the newly created section sheet "layout tabs" along bottom of screen.

But a regen soon revealed I'd created plenty of sheets. (like 3 sets of them)

Almost seems tied to this certain project for whatever reason. Done several others without this issue.

Thanks,

Jay
