spittle Posted September 24, 2008 Share Posted September 24, 2008 Can I use ordinary contours, breaklines and points (whatever I get in a survey) to make a grid surface? Instead of a TIN surface? If so, how? I've tried without succcess. Quote Link to comment Share on other sites More sharing options...
rustysilo Posted September 24, 2008 Share Posted September 24, 2008 You could create the tin from your survey data then create points on a grid from the surface or you can export the surface to a DEM which is likely what you'd be looking for. Just right-click the surface in the toolspace > prospector view > export to DEM. Quote Link to comment Share on other sites More sharing options...
rustysilo Posted September 24, 2008 Share Posted September 24, 2008 I may have misunderstood what you're looking for. Can you explain what your goal or application for this is? Quote Link to comment Share on other sites More sharing options...
spittle Posted September 24, 2008 Author Share Posted September 24, 2008 No it worked fine thanks, that was exactly what I wanted to do, though I now reallise it's not going to help for what I'm trying to do, I'll stick with the TIN.

rustysilo Posted September 24, 2008 Share Posted September 24, 2008 What are you trying to do? Maybe we can mash it out together. Quote Link to comment Share on other sites More sharing options...
spittle Posted September 24, 2008 Author Share Posted September 24, 2008 As you may be aware, surfaces created in civil 3D can be a little messy, even the tidy ones when to compare to how flowing you can make a mesh in 3DS Max. I plan to import one into 3DS Max and then I'll add some textures etc. I thought with a grid surface I'd be able to smooth it out easier but there are some pretty well defined holes dug out of my surface that I need to keep and if I leave enough space between my grid lines to make adding any iterations (same as how a spline works) effective then I'll loose the detail I need on my edges. Guess I could re-model the holes again once in Max and add a few chamfers so the holes won't be effected... Quote Link to comment Share on other sites More sharing options...
rustysilo Posted September 24, 2008 Share Posted September 24, 2008 What kind of holes and why do you need to keep them? Quote Link to comment Share on other sites More sharing options...
spittle Posted September 24, 2008 Author Share Posted September 24, 2008 Structures are going to be built in the holes and the landscape has been graded from the edge of the holes outwards. Ideally we want to create a series of images showing the workflow. I guess it's not essential to to keep the holes once it's in Max (in Civils they're calculating the cut & fill) but there will still be some triangles that don't look pretty that I want to smooth over.

rustysilo Posted September 24, 2008 Share Posted September 24, 2008 Could you create a 3D structure to drop in the hole? Quote Link to comment Share on other sites More sharing options...
