We have no idea how to attach a dwg file on a point cloud.
Our procedures are as follows:
1. Attach a point cloud (PCG file) using the command "POINTCLOUDATTACH."
2. Attach a DWG file using the command "ATTACH" on the point cloud.
Our results are:
1. The characters on the DWG object disappear.
2. The color of the DWG object change.
If anyone has information how to display correctly a DWG file on a point cloud, please let us know.
