Hello Everyone, I am pretty new to the Software but it looks really amazing.
I created some first traces (Compass Plugin) from my cloud. Now I tried to crop the points the trace plugin chose with the Segmentation tool and used Import polyline and imported the trace i created previously. Unfotunately, the segmentation tool wants to finalize the Selection with another point to create a 2D polygon. But my goal was to select and "segment in" the points along this 1D Trace.
Is that somehow possible?
Cheers,
Sv

Re: Crop 1D Cloud from Trace
What do you mean by "ants to finalize the Selection with another point to create a 2D polygon" exactly?
Is it because the trace polyline is not closed maybe?

When I understand this right, the segmentation tool needs at least 3 Contour points (left click). You close the polygonal selection after the 3rd one is chosen and close the selection (green polygon) with a right click.
I guess the Segmentation Tool is not the tool I need, because it is based on the polygonal 2D selection.
I need the cloud's points along the created trace, i.e. a 1D selection.

Then you could compute the distance between the cloud and the polyline (With 'Tools > Distances > Cloud/Primitive dist.').
Then you can extract the points which are really close to the polyline based on this distance (with 'Edit > Scalar fields > Filter by value').

Great workaround! Works just like intended !! Have a great week!
