This example uses a “Linked Circular Pattern”. This method is a little more involved to construct, but all cavities will update if changes are made to the original Cavity Body. This also makes use of the same “Circular Pattern Layout Sketch” (mentioned in the previous email) for driving all of the patterns in the model. This exercise uses "DOUBLE WALLED TRAY - Rotated Staggered Cavities - Linked Pattern - 20211006.ics" located in the example files.
