I'm trying to segment a point cloud into multiple cubes to export seperately since Blender runs out of ram if i import the whole cloud at once. To to this. I tried to use Label Connected Components to split it up but it returns only one Cloud. See files below. Any help is greatly appreciated!

Well, the "connected components" are indeed the parts of the clouds that are "connected". As you don't have any hole / ridge here, then you only have one "connected component" in your cloud.

You should use the "repetitive slice/box extraction' option of the 'Cross Section' tool (see https://www.cloudcompare.org/doc/wiki/i ... r_contours).

You can define your initial box, and the tool will repeat the segmentation process by moving the box in one or several dimensions.
