AutoCad Civil 3D 2009

Hi, I use autocad, but I'm absolutely new to autocad Civil, I need to do a Profile of a street and some sections, I have the center lines, the curves with elevations, but I have no clue how to do the profile. I did an alignment with the street center line but the profile turns out flat, how can I take into consideration the curve lines with elevations so it does the profile correctly taking into consideration what I have?

Step 1: Create a existing surface using your survey points and break lines.
Step 2: Create your alignment <done>
Step 3: Create a profile from a surface -- this will give your profile the height you need.
Step 4: Create a proposed profile by layout. Use the tools on the toolbar to create tangents and curves.
Step 5: Create an assembly (typical section)
Step 6: Create a corridor using your alignment, profile assembly.

Hey, thanks, I'm sorry to bother but, how exactly do I create step 1? "Step 1: Create a existing surface using your survey points and break lines."

I mean, there are so many types of surfaces when I click create surface. Which one do I use? triangulation? grid? volume?

Thank you very much..!

The link in the attached thread will help you out, there are a lot of videos out there for free that tutor you through this stuff, most are only 20 minutes long.

Create TIN surface. Volume surface is for the volume difference between two surfaces. You most likely will not have a grid surface (points on a grid); you more likely have grid points supplemented with points on breaklines, etc.

The help files are very good. So are the Autodesk-sponsored books, which at around $70 each, are pretty cheap for training.
