Point Pick List with selection box/snipping

[dannyht]

Hello! I believe there is a way to do what I'm trying to do, but I just cant figure it out.

Background: I'm on a research team at GaTech and our task is to create an algo to analyze LiDAR data and identify and assess traffic signs. Data was acquired via a van with a LiDAR unit. The point clouds that I load in are...very long. I've been using CC to verify our results by importing in the original LiDAR point cloud dataset and as a cloud and then importing the dataset that corresponds to what we think are points that belong to signs (as a different cloud). I change color to help differentiate and see if points line up and such. It's actually been working well!

Question: Is there a way to "batch" create a point list? From everything I've read, you can only create a point list by selecting points individually. However, it would be nice to be able to have a selection box or a lasso or something to select and add the points to a point list so that I can export them out. This would be very useful as I could get the points that belong to a sign, but that our algo didn't pick up.

Thanks so much for your help!

Well you can always use the 'scissors' tool to segment out some points. And then merge them or export them directly? (see https://www.cloudcompare.org/doc/wiki/i ... ation_Tool)
