Just noticed in SU2026, after importing and moving a pointcould, the section planes in the project become really large. I guess related to the translation of the pointcloud? So when doing zoom-extends when a section plane is visible, the project contents become very small. You must make sure to hide the section planes for zoom-extends to work as expected.
This isn’t specific to point clouds. It’s normal behavior. The section plane size is determined by the enxtents of the model at the level of the section plane. If you don’t want the section plane to enlarge with the placement of the point cloud. Group the rest of the model with the section plane and leave the point cloud out of the group.
Not a point cloud but you can see the same sort of thing happens with other entities.
Moving entities.
Adding an entity.
Putting the section plane in a group with part of the whole model.
Thanks for the reply Dave. This is all know to me but its highly impractical to have put everything into a big ‘container’ just because a pointcloud is imported that drives the boundaries ‘insane‘.
Is there geometry in the point cloud that is very far away causing the expansion of the section planes? Can you delete it?
It would be the same if you import anything that is huge. As I wrote before, that’s not specific to point clouds.
As Mike asks, is there anything at a huge distance from the rest of the cloud?
hello, there are problems with point clouds transformation with current (scan essentials) build, and there will be a fix by the end of the year.
for now it is best moving the clouds close to origin within source software before importing them in sketchup.
working with point clouds that are far from world origin, even if you move them or ask them to be moved close to origin upon importing, can lead to many issues, such as loss of definition/cloud density. I’m pretty sure it also affects what you see with section cuts, and I experienced it as well
on the other hand not moving them can lead to clipping and other issues.
I spent much time moving clouds in recap because of that, but the devs are aware of that and are working on it

thanks for the suggestions and replies Bmike, DaveR and Paul,
The pointcloud is cropped and moved with its center of points at the origin in cloud compare. Just a small ‘box’ with points - no stray points. In SU, using TSE, it does show near the origin for a split second and immediately jumps to a far away position.
Good to know its an issue thats being worked on.
