LiDAR _ AutoCAD

[faruqi]

Hello,

 

I am curious in finding out if data collected by a UAV, using LiDAR, of a building / facility under construction can be transferred back to an IFC design to capture deviations and thus prepare an as-built.

 

UAV will be equivalent of a surveyor trying to capture actual construction and updating the Auto CAD design

You can turn points into meshes, but it is a lot harder to make actual objects (like in IFC)

Also, meshing (unfiltered) pointdata will give you extreme great deal of data.

I tend to use pointclouds only to check details, not the whole structure ..

 

 

Good to bring it up, faruqi,

LiDAR is useful when looking at big picture scenarios, e.g. concept design.

 

I have found it to be of little use (design/output wise) when you need accurate survey. It is generally quicker to do the work using more traditional pickup ways.
