Hello Ben,

There’s no direct way for inserting 2 grooves for sliding doors.
The way to do this is to create a fitting or hardware that has two grooves with their right size and spacing.
You will also need to create the rule to position them, and apply this as a fittings link between the door and the top and bottom of your cabinet.

I attach to this post an example cabinet with two sliding doors 10 mm thick and set up with the hardware and rule into two grooves.

Note that we cannot extend the doors into the grooves using this method, but we can add the extra material to the doors to the cuttings list either by adding over sizing to the height of the doors or by applying edging material with an negative value.

For a more detailed explication of how to set up these doors and eventually if you want me to make a little video explaining the details, please subscribe to full membership.

With full membership I will also be able to set you up a complete and detailed template according to your specifications, and that will probably save you a lot of head scratching and time.

I’m sorry I can’t post on this forum in French, will be setting up a French in the near future and I’ll certainly keep you informed.

Hope this is helpful, 

All the best,
Ness,
