Hi Guys, wondering if you've ever had this issue and have figured out what/why my CAD keeps crashing, and if there are any work arounds/fixes for it.. I have a few different surfaces I've created from lidar and survey data, and they keep crashing my AutoCAD especially when I'm switching between layout tabs, but really doing just about any command haphazardly... I know it's the surface because I can set it to no-display or just turn off the layers and i'm smooth sailing, but with it on i usually crash within 10 minutes. I have a pretty killer computer and it's not that incredibly large a surface, so I'm wondering if it couldn't be something else that's bogging it down...I've tried a few different things but nothing seems to help. getting a littttttttle annoyed, and I've done everything else on the drawing but can't seem to finish because this guy keeps crashing. Any help would be greatly appreciated! Running: Civil 3D 2012

Hi. I've bought lidar height and surface info from a mapping company. This is in DWG format which along with (DXF and GIS where the only options). I have since downloaded trial copies of Civil 3d & Map 3d to go with my copy of Vanilla 3d. All of my programmes are Release 2012. I am finding it impossible to make a surface in any of the programmes, because they also seem to want the point (which I can see and rotate around, but not make into a surface) in a file format that is not DWG. Even though they are available as editable points in the file. just not editable enough to make into a surface - get it? now i know from other threads that each programme manages points differently, but all i want to do is make it into a surface with contours in any of the programmes. although the categories function and density function of M3d would be use full. As it stands I'm being really inefficient using this Lidar info in these programmes as what I really need is heights of surrounding buildings and trees. I had hoped that using these auto desk programmes would improve my workflow. Any help is most welcome. I attach the original survey file for reference.
