I'm using Quick Terrain Modeler (QTM) 64-bit v220.127.116.11 - I have a set of LiDAR data that has some points that I want to delete, but due to their location it is hard (if not impossible) to delete them by merely using the
Select Polygon (Screen) tool without deleting other desired points.
So, the way around it is to use the
Start Mensuration tool and then select
Profile Analysis Tool in order to cut away specific points. However, this can be a bit tedious and not always a one-shot process. I found that while in the Profile Analysis you can select
Mask to Area in 3D, in which (temporarily) only the selected area of interest is shown. Once in this view, I choose the
Select Polygon (Screen) tool again and select the bad points and then cut them. However, this cut still deletes the points behind the bad ones, even though I've temporarily made everything else disappear.
So my question is this:
Is there a way use the
Select Polygon (Screen) and
Cut tools in conjunction with the 'Mask to Area in 3D' selection, without cutting/deleting points that are not visible/in the area of interest?
Here's an example of what I'm talking about. The first picture is with
Mask to Area in 3D turned on and I'm cutting the faulty points. The second picture is showing the unintended cut, after turning off
Mask to Area in 3D.
