How can I duplicate the small sketch to an array of a 3X4 pattern on the large slab?

This is probably a working order problem. As you can see, I’ve made an approximation of the design, but it’s very haphazard and incorrect.

Use the **Pattern** tool. If the end result is to extrude the 3x4 pattern into bodies then one might consider using the initial sketch to extrude one body. After that you can make the 3x4 pattern of the extruded bodies. The idea here is you’ll only need one sketch to start with.

Thanks. I did extrude the single body, then used Split Body to separate from slab, then applied linear pattern, first 3, then, with 3 selected, applied 4.

When you extrude off the surface of another body you can choose to make it a new body. I often forget that.

Thanks for that, also. Much appreciated.
