Creating a surface and designing a road on it

[Ahmed137]

Hello, I'm new to autocad and I had a couple of questions hoping you guys could help. I have an as-built of an area and I wanted to make a surface out of this data so I could build a roadway on it. Any tips? Thank you

You will need to use AutoCad Civil 3D or a similar program. Are you using Civil 3D?

I am using AutoCad P&ID 2012. I can change the view to different isometrics

Land Desktop or Civil 3D. You can get the surface elevated by the surveyor. If plain CAD you have to design from a plan view in 2d.

You don't need 3D for such work, you can do such work in 2D, however before you do and if you did not have a surveying course, you should consult a surveying textbook by such authors as Davis and Foote and published by McGraw-Hill covering such subjects as profile, cross sections, curves. Less extensive coverage of the subjects that I mentioned would be covered in Civil Drafting Technology by Terence M Shumaker and published by Pearson/Prentice Hall. 2D drafting, as far as I am concerned is more challenging because it allows you to visualize about the directions and spacing of the elevation lines where you have fills and cuts, on the roadway on which you may have a crown and curbing, and in the drainage ditches.
