building face deviation analysis - point cloud & model

Postby CloudSC » Tue Jan 24, 2017 11:05 pm

I am interested in performing a deviation analysis on the face of a building and apply a heat map to the face, as well as to perform cross section evaluation on the columns, which have about a 15’ spacing along the building. When I bring in a point cloud into Cloud Compare, it does not align well with any of the main face views and the heat map is not developing properly. I am not sure how to perform cross section analysis of the building face for flatness and or deviation. I would also like to compare the point cloud face to a CAD model design, for discrepancy. I am also interested in identifying what types of data can be generated and presented for use in evaluation of the flatness profile or the two combined profiles.

I guess you could re-align your cloud first? (with the Graphical Transformation tool -, or the Level tool for instance -

Or you can play with the camera ( and then save various viewports (

And for the columns, you'll have to separate each of them in new point clouds with the scissors tool for instance:, or the cross section tool ( This last tool can help you to make... cross sections by the way ;)
