I was recently certified by Autodesk as a Civil 3D Implementation Certified Expert or ICE. I have worked in the Civil Engineering industry since 1987. In 1994 I started my consulting business doing training and consulting for Civil Engineering customers utilizing Autodesk civil engineering technology. I started L.A. CAD in 1999 and we are currently the 3rd largest Autodesk partner in the U.S. Studied Civil Engineering at Long Beach State, graduated in 1996.

3-Line Profiles (revisited) and workflow

Check out the following screen capture of the 3-line profile in the "Profile Base" drawing. It shows station/elevation for grade breaks. The Profile Style being used is a "3-line" style that has been preset to NOT show a profile grid and include a label set that shows station and elevation for all Grade Breaks along with the grades. Many companies store their profile grids in the Sheet Files, so this method assumes that the grid will be in the sheet files.

The above drawing exists in the Profile Base (per Vault and Project workflow) and is Externally Referenced into the Sheet files. The Profile View style applied to the profiles suppresses the grid. The 3-line profile shows the Right TC in the bottom view, the FG Centerline along with the EG centerline in the middle view, and in the top view, it shows the Left TC.

The Workflow consists of applying a Profile View Style that incorporates a grid initially, within the Profile Base drawing. Once the 3-line profiles have been created (per a previous post I made)... http://digginginc3d.blogspot.com/2006/10/3-line-profiles-in-civil-3d.html you would move the middle and top profiles down to "compress" the view of the 3 profiles... essentially moving the 3 profiles closer together. When moving them down, you should use object snaps to select points on the grid (of the top two profiles) so you have equal spacing between the 3 profiles. Once you get them close enough to where the annotation is still readable, you would then apply another "preset" profile view style (called "3-line profile view", as an example) to the 3 profiles. This style again would suppress the grid since the grid is contained within the sheet files.

Based upon the screen capture above, you would want to ensure you have created appropriate Civil 3D Label Styles that label the 3-line profile correctly for grade breaks and vertical curves on the finished grade. Although this is a work-around to having a real 3-line profile command in Civil 3D, in the event that we dont see this command soon, this is an acceptable work-around that is quite efficient.
