West coast side bearing blocks

I’m currently cading a west coast drive and I’m trying to integrate west coast products side bearing blocks but am having trouble putting squarish pattern into the box tubing in the cad. Does anyone have any suggestion on how to do this. Also I’m using auto desk inventor

I have done quite a bit of cad in solidworks with the WCD side block and other parts. Could you give some more information on what you need help with?

Could you clarify? Are you trying to do a cut-out pattern, or create slots for the bearing blocks?

It sounds more like you’re trying to do the latter, in which case a rectangular cut-out via extrusion would likely be the easiest way to go.
