How to derive contours and levels from a point cloud in Revit

[justin]

I have a point cloud rcp file from a client and wish to extract contour information and/or levels from the point cloud if possible. In Recap I can measure between points but would like to be able to measure the existing buildings that I have in the point cloud in Revit - is that possible? When I bring the rcp into Revit I can see the point cloud and it is useful for seeing my proposal in the context of the existing neighbourhood, however I want to be able to check spot heights on the neighbouring buildings' roofs and derive contours from the topography that I can see in the point cloud. Please can someone help me to understand if it is possible to take levels and measure distances on a point cloud in Revit? 

I am working in Revit 2019.

You need to manually place references (Levels, Grids, etc.).  Depending on how the PC was created, you may or may not have snap points.  If not, you have to eye-ball placement and fine-tune placement by making some educated assumptions, like assuming the floors and walls were built level and plumb.

@barthbradley Thanks, that's helpful. So basically there is no automated way to get contours or spot heights from a point cloud in Revit. Do you know if there is a way to get that kind of information from a point cloud in Autocad? And then take that from Autocad into Revit?

You can open the .rcp in Autocad and extract some intersecting lines/planes. Click the point cloud and have a look under extract (edge/corner/centerline/section line). Works better then with Revit to find some references I suppose, but.. could be better.
