Point clouds should know the scale of the document they are going into and attempt to scale accordingly. Point clouds typically are meter by meter by meter for scaling size - if the point cloud goes into a layout that is in MM it should scale - or if it is into an inch layout it should scale to imperial - if nothing else, have it work similar to block inserts in AutoCAD for the interaction. (see attached) IT is very confusing for the users in imperial - typically the cloud comes in 254x too small.
