Once in the 3D Viewer, multiple boards can be repositioned using the Fold Board command. These are non-flexi boards. If using flexi boards, use the Fold flexi Boards command.

The ability to fold boards is enabled when a pair of Board Origins are inserted into the PCB design and the Board 3D Origin set with folding parameters.

Locating this option

Within the 3D Preview window, it is available from: 3D Design menu > Fold Board option

Using the Fold Board option

You must run the 3D Viewer option from the 3D Design menu from within the PCB design editor first, this will create you a 3D Preview.

Now you will have two or more, multiple boards displayed. If you only have one board, this option will not be available.

You can run the Fold Board option from the 3D Design menu. This option will toggle between the folded status and not folded status. Once folded, you are able to move components on the folded board, and can also move the folded board itself. Moving the folded board will result in the offset values defined in Board 3D Origin Properties (for the corresponding board origin) being altered to match the fold transform that will be required. 3D view will regenerate to update the positions of all the items on the folded board.

With multiple boards displayed, you can now rotate the designs in the viewer and also run Clash Detection on them.
