How do I edit a 3d library object?

I want to make this 2 holer recessed toilet paper dispenser into 1. how do i do it? i can get into the 2D version of it and delete half of it but it doesn't change it in 3D.

 

Thanks,

2d is simply a representation of the 3d counterpart. Complex to get into the details of this but what you are asking for is editing the 3d mesh geometry of the object. The delete surface tool can temporarily delete clusters of polygons(based on the smoothing angle of the 3d object as designated in the 3d panel of the object). When you have temporarily deleted the surfaces you want to remove, then with the object still selected, choose convert selected to symbol from your edit toolbar.
