Hi Tim,

The easiest way to insert windows is to use a wall.

You can use a cabinet but don’t use the same materials  as for the other cabs.

Here’s a video:

You might need a training session for me to show you the tricks of using images, wall etc..

As a full member you have free mini Team Viewer sessions (up to 15minutes) or you can buy oneof our training packages here:

Don’t forget that if you buy Polyboard you already get one hours free training  and set up

hope this is helpful,

All the best,
