Hi Oscar,

Polyboard will not make the doors open and fold as you want.

However you can set up the doors with the correct hardware.

First use the fittings links menu to erase the hinges on the side you don’t need them.

Then select the second door you inserted and open it’s link to the first door.

You can then apply the hinge and it’s positioning rule. 

I attach a couple of models that have the hardware set up.

You can see how they are set up and use the hardware restore function to insert the special Blum hinge into your existing libraries.

Note that the second door is always “over passing” the first.

To make the doors open the other way you must add the doors in the right sequence.

Hope this is helpful.

All the best,

Ness
