You can duplicate a feature or a current solid as many times as you want by
specifying anchor points.
Before you begin:
Create a wall, a wall on edge and a cutout on the wall on edge. Create a sketch
containing points.
Ensure that these features lie on a unique and planar wall.
From the Sheet Metal section of the action bar, click User Pattern.
In the Object to pattern, select the cutout to
duplicate.
In the Position box, select the sketch.
Important:
By default, each instance is positioned with respect to
the center of gravity of the element to be duplicated. To change this
position, click the Anchor box and select another
vertex or a point.

Cutouts are created at the points of the sketch.
