Hi SketchUp people
I’m attempting to create a 3D model of a proposed detention dam and have been struggling to import an existing ground surface, upon which to base my modelling. The surface in question has been created using Lidar data (pointcloud based on aerial survey data .dxf/.dwg). The surface is large (in data terms) as a result of this, and while I can get everything into my model, it’s understandably hard on the display and slows everything considerably.
What I’m looking for are suggestions around how I might remove some of the density from the surface. Can I, for instance, convert the .dxf/.dwg into another form of surface.
I realize that SketchUp might not be quite the right program for this scale of modelling, but I am limited to the tools I can get my hands on. I currently have access to programs for road design and survey, which are not really cut out for rendering etc.
Any help people could offer would be greatly appreciated.
Thanks in advance.
