Long Section and Cross Sections

[timi]

Hello!

I'm new to the forum and I’ am a new user of the cad programs .

I’ am working like surveyor in topography on the progect of a road.

I have some DXF Drawings files in AutoCAD.

In drawings ( dxf.1.a and dxf.1.b) I have points that I measured along a river and imported in Autocad Land 2009 from my GPS Trimble R6.

In Drawings (dxf.2.a,dxf.2.b,dxf.2.long section,dxf.2.cross sections)I have The long section and cross sections of the plan in Drawing.1.How can I realize some thing like that?

I want to learn how to arrive in Drawing.2 if I began from Drawing.1.

How to get a long section and cross sections from the plan in Drawing.1 ?

I have Land Desktop 2009. What I have to do?I have to create a surface before or what?Can you explane me the way to create long section and cross sections?.

Thank you.
