Does anyone have experience of point clouds?
My interest is Architectural - buildings and site topography - but experience with plant, civils etc couild be relevant.
Primarily inputting to Brics or other dwg - but experience with other, point-cloud-capable softwares (Bentley etc) could suggest possibilities.
So if I've employed surveyors to produce the point cloud, what next?
Some have software (Bentley etc) that claims to automatically generate 3D vector CAD model from the point cloud data. To even handle point clouds, surveyors already have the big fat computers that this requires.
Others treat the point cloud as if it's the building, but brought inside their desktop computer.
They take measurements off the point cloud, just as they would the actual building, and manually produce the conventional 2D survey plans/sections/elevations, or a 3D CAD model.
Sounds laborious and expensive!
Some deliver the huge point cloud data set to the Architect, who him/herself takes the measurements and draws as above, when and as needed at the various stages of their process. Needs big fat computers.
In any of these cases, the Architect can have the point cloud as a misty etheral colour image, which can be overlaid on his/her 3D model (if working in 3D) and can be used in presentation, visualiation 'in context' etc.
What do we know about all this - what is best practice, what is cost-effective?
