A variation to add to this post. This window does not use a dummy frame to aid placement. Instead, The window component is exploded straight after insertion. Each cutting sub-component and the window itself has a red 'Gizmo' as part of the component. These are placed away from the wall so they can be selected more easily. All the gizmos are occupying the same position. Now, by selecting the gizmos, the window plus it's wall cutters can all be moved together. The gizmos are on a layer (Tag) of their own and this can be turned off when not required.
I have added a simple setting out range for bricks, in this case 225mm for a brick and one mortar joint. Using this, windows & doors etc. can be set out to make the bricklayers' life easier!
New window component placed on left. Window on right exploded.
Window & cutters selected by gizmos. Can be moved using setting out range.
Gizmo layer (tag) turned off. Inner & outer wall leaves cut.
