I personally cannot help with this other than ask, "Have you done the Plan & Profile Sheet" tutorials that comes with the program?
If you have not, then please do it.
You can find tutorials by selecting the down arrow next to the question mark at the top of program.
Sorry but there are no quick answers to this question.
A few of the things you'll want to read up on to create a working Plan & Profile dwt are:
- Viewport Types. Civil 3d has 3 specific vp types, Plan, Profile and Section.
- View Frames
- Match Lines
- Alignment Label Sets
- Profile Label Sets
- Profile View Data Bands (possibly the most challenging component).
- View Frame & Sheets related Feature Settings and Command Settings within the base.dwt the View Frames &
- Sheets will be created in.
- Page Setups.
Providing some specifics on the problems your running into and a screen shot of what the Plan & Profile your trying to create is supposed to look like will help.
