I’m trying to turn a 3D point cloud (Imported from autocad - they’re actually very small cross hairs) into a surface topography. However I can only seem to set my patch settings to 30x30, anything above will cause Rhino to crash, telling me that windows is out of memory and will abort the operation. Unfortunately 30x30 doesn’t capture the detail of the topography very well.
I’m just wondering if there is a better way to do this? Is my issue perhaps the fact that these are little cross hairs rather than points?
