Point Clouds in Revit 2014

The underlying engine for Point Clouds has been redesigned and implemented in Revit as well as in other Autodesk products. This effort is the result of integrating other technology acquisitions Autodesk has made (Alice Labs primarily and RealViz) in the past year or so. You’ll also want to check out Autodesk ReCap when you get a chance, image below.



The new point cloud engine uses RCP/RCS formats. The RCP format is a project file while an RCS file is a scan file. A RCP file is a group of multiple RCS scan files. If you have raw data in other acceptable formats Revit will index it in the background and let you know when the indexing is complete. It is also possible to run the indexing apart from Revit using Autodesk ReCap which is included as part of the Building Design Suites (image above).

There is a command line approach available too, using the “AdPointCloudIndexer.exe”. This application is stored along with other installation data in the Program folder. Ben Malone (BIMopedia) and Luke Johnson (What Revit Wants) wrote about this on their blogs shortly after 2014’s release. This is a link to Ben’s original post.

We can now control the colour mode for each point cloud import using Visibility/Graphics.



They enhanced Revit’s sensitivity to points and planes within the point cloud data. This should make it easier to sketch model elements using the underlying cloud data. Revit will detect planes that are perpendicular to the current work plane and very close to the cursor. Zooming in the view will cause Revit to reset the view and it will be necessary to detect a plane again. Snapping directly to point cloud data is a low priority in snapping order. Planar snaps are the initial focus for detection. You can use the TAB key to cycle through other possible snap options.
