Posts Tagged ‘Point Cloud’

Leveraging point cloud data can be an effective tool in creating an accurate model of a difficult space.  Take this room for instance:

This space has crumbing walls, no ceiling, collapsing duct, and creates a condition where individuals can’t visualize what the space could look like.  How do we communicate what this space COULD look like?

For us we started with a quick point cloud scan then brought it into Revit:

From this scan we were able to model the room’s current dimensions accurately (as well as the falling duct) in order to produce a conceptual illustration of what this room could look like as a blank slate.

From there we could have modeled it more, but it worked for our purposes. I did this rendering with the duct “falling down” as a visual que that yes, this is the same space, but that we could replace the duct and easily “clean it up”.

The entire time to complete:  For two people, one working on the scan and one working in Revit, we could have started the scan at 9:00 AM and been to a point where the “white” model was done by 3:30 in the afternoon… including lunch and the 30 minute drive back to the office from the site.

If you would like to know more, let us know ( you can email me, Brian Myers, at bmyers@seilerinst.com ) and we’ll be happy to discuss.

This video (it doesn’t have sound) shows the process of importing in data from a Point Cloud file into Revit. In this case, it’s from a Faro scanner. The initial conversion process that you see is because Revit only utililizes .PCG files and it needs to convert any other format to this. In the case of Faro, it’s an FLS file.   This video isn’t intended to show best practices, instead it demonstrates how Revit imports in this data and the speed of which the data can be moved once it is brought in. The original Point Cloud file (FLS) was 106mb in size.  When converted to PCG it ballooned up to 671mb.

Behind the scenes magic:  The only thing that was edited in this video was the conversion time. It took my computer 8 minutes (in real time) to process the conversion from FLS to PCG.  Everything else (panning, zooming, sectioning, etc) in Revit is actual speed…. even the speed it took to import the created FLS file is real time.  My computer specs:  8GB of RAM,  Intel Core i7 CPU (1.60 ghz) and Windows 7 64bit.  So, average speed (at best).

The video can also be downloaded from the following link: http://dl.dropbox.com/u/9805131/Revit%20FLS.wmv
