So, while these 3D elements can be imported into Revit, the latest
functionality introduced to Revit 2015, as mentioned at the start of this
chapter, is the ability to import files (for example, ACIS solids in the form of
SAT format files), explode them, and retain the 3D elements. This lets you

other Revit solid object. This function has the potential to greatly help in the
transition from one file format to another.

can be stretched and manipulated using shape handles, any radii remain
static, even though they can be dimensioned.

examples. On the left, an ACIS solid created in AutoCAD and imported into
a Revit mass can be seen. Notice the grips on each face but no controls on
the arc. On the right, a similar model has been imported from SketchUp.

Point Clouds
Point clouds are beginning to be the new import for existing conditions.
Obtain a laser scan of your building and it's a simple job to check design
data against the As Built model. Revit supports a wide variety of formats
(including PCG, which was the default file format in previous versions). In
the 2014 release, the point cloud engine was changed to use RCP and RCS
formats; the others must be processed on insertion into Revit. You can do
