What is everyone’s opinion on the better software for terrain modeling, Sketchup or 3DS Max? Starting a new project and want to streamline as much as possible. Thanks!
September 19, 2012 at 5:45 pm #156355Phil MooreheadParticipantAre you importing CAD drawings or starting from scratch?
September 19, 2012 at 6:30 pm #156354Scott BensonParticipantI am importing topo data from CAD. I also need to “drape” other CAD lines onto the terrain. I know how to do it in SU, but I have recently started using 3ds max and didn’t know if there was a big advantage to creating the terrain in that program or just building everything in SU and importing. thanks!

You have the most control that way & then could export either a TIN or breaklines (feature lines in Civil 3D) into your rendering program of choice. Might be overkill if you don’t need survey-level accuracy, though.
September 19, 2012 at 8:01 pm #156352Scott BensonParticipantI do have civil3d actually and higher the accuracy the better. (I am modeling a before and after grading plan for a large scale land development) Thanks for the help, I will give it a try.

Just keep items you don’t want interacting in different “sites”, much like SketchUp groups and you’ll be fine. Civil 3D has many useful tools for editing the feature lines, such as by slope, by reference surface (“draping” on existing surface, for example), etc. Build your finished surface with feature lines, individual points, manually drawn contours, or whatever combination is needed.
Adding interactive surface labels for spot elevations and/or slopes, that automatically adjust as the terrain is edited, are mighty handy and a good check for problem areas. The help files should have all the information you need, if you have the time to go through them. Good luck!
