how can I move the center of the scene(a ball) to the reconstructed object

[buaakevin]

in the dense cloud map of the whole scene, the object I want to reconstruct is only a small part in the whole scene. I want to move the center of the scene(a ball) into the reconstructed object, so that the export model in pdf will be easier to contral.
what I should do?
thanks for helping me in advance.

Hello buaakevin,

You can select the area to be reconstructed using Boundg Box and Rotate/Resize region tools.

And as for the default view in the exported PDF file it is the same to the current model view.
