    Cross-reference item numbers in assembly drawings

    Context: I'm creating an large assembly procedure, with lots of exploded views, and step by step instructions to assemble a machine. I've got the Top Level BOM on the first page, and then for each "Step" (which is a configuration of the assembly) I've got a separate page, with the exploded...
