Can someone please explain the phantom geometries?
These are the same shapes as objects which should be cut-off by the section plane and is more than away from those obj.
They look like shadows on the Section Plane but I can’t find anything anywhere about this.
I’m not sure what you mean. The Zorro2 plugin actually cuts through the model where you tell it and unlike a section plane, it actually cuts and removes the geometry geometry on one side of the line. This makes it look like a section cut but it will render in Vray or other renderers. If you want to make a number of different views of the same model, save out multiple copies of the SKP file and cut each one where you need to cut it.
