Create Section with Drape Element on Point Cloud (Descartes V8i SS4)

Hi everyone,


I've tried to drape a line element on a point cloud of a scanned cavity (see picture below) to generate a section through the cloud. Is there a way to avoid these spikes (red circle in the picture) by chosing something like a maximum distance between two points of the polyline? maybe there is another way to create such a section/polyline.

Thanks a lot for your answers!

Greetings..
