Analyze surfaces with Point Cloud Analysis in Revit

Analyze surfaces in your Revit model using the Point Cloud Analysis tool in Autodesk Point Layout.


00:03

In Autodesk Point Layout, you can use Point Cloud Analysis to ensure that a surface is within tolerance of the specified deviation allowance.

00:13

A Point Cloud Analysis can be performed in a 3D view on any surface, in a section or in a plan view.

00:22

This allows you to compare a point cloud to any corresponding surface in your Revit model.

00:28

With a model open in Revit, from the ribbon, Autodesk Point Layout tab, select Point Cloud Analysis.

00:38

In the PCAnalysis dialog, specify the maximum point distance, or deviation, from the surface.

00:47

Here, the value is set to 2.

00:50

Click OK.

00:52

Note that the point cloud must be properly positioned within the model.

00:58

It is recommended that you use a total station in conjunction with your point cloud to tie control into your job scan.

01:06

In the drawing, select the surface that you want to compare with the point cloud and then, on the toolbar, click Finish.

01:16

The face deviation legend appears in the drawing.

01:20

Zoom into the surface to see a heat map.

01:24

In this example, the report indicates that everything on this wall is within tolerance.

01:32

Now you can analyze surfaces in your Revit model using the Point Cloud Analysis tool.
