Is there a way to automatically make slots on a semicircle?
Design an offset circle and a line then use the Trim Shapes Tool to remove the upper part after remove the line.
Duplicate the left rectangle, select rectangle and the semi-circle and Copy Along Path, adjust until the last rectangle is in place (as the rectangle at right you already have):
At the end remove the 2 duplicated rectangles.
Thank you for this, that’s what I needed!
