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,

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!

Cheers!
