Hello!as i said, the title bugs me. i downloaded a 3dplant block of this site, if i insert it to acad - renders fine. if i OPEN it with ACAD or Civil3d - renders fine. but, if i INSERT it to Civil3D - rendering draws a solid black square. no image. i only recently noticed this as i configured some point groups to have these 3d blocks as markers..thanks for any ideas!
