This document will explain how to create an "opening" such as a window or a door and place it in a wall.

First, we create a new cabinet item, as a custom shape, which represents the opening.

Example

As shown here, 'Outlets' have been added by creating a custom shape cabinet item.

Then, you need to specify at least two steps...

1. The outer contour will be in a normal layer, however the internal contour will be in a minus layer.
2. Add a new property "_IsACustomShapeItem" and set it to "true". When a wall is drawn it will look for any cabinets with this property.

There are two ways to place the opening, either in plan view or elevation.

When a cabinet has been specified as an opening, the collision logic is turned off so that it is able to be placed "inside" the wall.

Notes

1. Cutouts do not have to be the same depth as the wall. Depths of the opening can be less than or greater than the depth of the wall.
2. Cutouts can be placed in plan view
3. Deleting a wall will not delete the opening. You must delete the opening manually.
