Using Point Cloud tools to convert any (?) 3D geometry to Revit native geometry

Luke Johnson

Could we laser scan the world, make a big point cloud, and then import it into Revit?  Well, one day we might be able to accomplish that on a small scale (then again, maybe not).  In the meantime, try this process:

  1. Make the point cloud from existing geometry using this guide
  2. Use GreenSpider (more info at this link) to bring the points into Revit (and ‘maybe’ make a form using splines)

I’m sure results will vary… please comment if you try it out.

    Have you heard of GreenSpider? The Revit point cloud importer?

    It is an interesting add-in for Revit that can import point data into the conceptual environment.  It was written to “narrow the gap between computational concept design, terrestrial laser scanning and Building Information Modeling.”

    Some info:
    GreenSpider conveniently parses ASCII text files representing 3D vertexes, whether generated by computational modeling software or terrestrial laser scanning equipment.

    Once installed through this installer package on Windows-based pc’s, GreenSpider 2.1 can be accessed in Revit mass modeling environment.
    …
    GSpoints and GScurves. The first one simply imports vertex point cloud as reference points in mass modeling environment, while the second traces a spline interpolation among imported points sorted through a TSP process, in order to build surfaces after recursive .GSP imports.

    …
    Decimated laser scanner point clouds are imported this way in Revit as many times as needed (using a reset function every time in Translator module), and generated curves can be used to originate surfaces very close to their real geometry.
