Hi Michel,

It’s not actually possible to set the middle door to the front.

If the doors are on rails this shouldn’t usually effect the manufacturing data.

For presentation purposes you can trick Polyboard by making the back of the cabinet the front.

To do this delete the back and use the “slack in depth” parameter of the doors to put them at the back:

You can add a back to the “front” by adding a door.

Hope this is helpful,

All the best,

Ness
