Hi,
Currentely, it is imposible to import meshes from Memnto to Revit.
Why to import meshes int Revit ? See three raisons below :
1- when you will try to make a rendering on points cloud ==> the points cloud disappears,
2- you can't have shadow on on points cloud,
3- in perspective view, you can see through points cloud,

An idea : could be possible to implement import FBX format capability for Revit for instance !
