CloudCompare forum

Hello,

I have to pointclouds, which are already aligned. At the beginning I subset the data by Using the "Cross Section"- Function. There I can set the center and the width of each Bounding Box, which are I define as the same:

Example: Center( x: 1, y:2, z:0), Width (x:16, y:16,z:13)

But after I export or create the subset die dimensions of my bounding boxes changes to
( x: 1, y:2, z:0.182), Width (x:16, y:16,z:11.7127)

Is there a way to fix the bounding box?

The bounding box fits the actual points in the cloud. This is probably why the box shrinks and its center shifts a little.

So apart from adding fake points to force the bounding box extents, there's no way to set the bounding box size.
