thanks for the reply.

 

we did actually used to use civil 3d but had to get rid of it due to lack of use (hence the question) but i think i've found the solution now. 

 

It was only a small area of a site that needs to be modeled so i simply added the z value to the relevant points and used a plugin called 'Point Cloud' that effectively droops a mesh over the points to create the surface. Bit of a ball ache though as i had to manually input the z data, but got there in the end!

 

Cheers

It's not a simple task. To do it properly, accuratetly, that would stand up in court, you need information provided by a registered surveyor; a ground model created using industry-standard/approved software such as Civil 3D, eaglepointe, several others; performed by someone with the necessary training.
 
OK if you just want a 3d representation you can manually draw elevation contours through the points, make polylines, use methods (autocad commands) to convert to a surface or solid.

i seem to be having great difficulty with this simple task... please help!

 
i need to create a 3d model of an area of land to show how flat (or not flat) it is.  I have point data covering the area of interest that has the 'z' value already entered so all i need to do is create a 3d surface from this information right?
 
how does one do this?
 
Many thanks for any help
