Point Cloud - Extract Points
« on: March 07, 2019, 07:13:38 PM »
Does anyone know of a way to extract points from a point cloud that are within a given boundary?  I'm working with Recap .rcs files.

Hoping for a LISP method but other ideas would be appreciated...

The only way I think this can be done would be to convert the .rcs to a point file and either work with the converted file or build a database and work from the database.

Cheers!
Rob.

It's been a bit since I worked with point clouds, but couldn't you create a surface using those points, add a boundary to the surface, turn on points in the surface style and 'Extract Objects' ? Or does this method exclude points from density limitations?

I have a tool (actually set of tools) for analyzing tunnel sections.  A surface is a 2.5D (2D with elevations at nodes) and to analyze tunnels I need 3D points so that top/sides can be estimated.
