A component (or a group) is not a solid, so you can’t perform solid operations with/on them. I’m curious how people handle this situation. The case that’s driving me to post this question is that I wish to trim one component with another, where solid 1 (in the tool’s terms) contains nested components. One strategy would be to explode the component, perform the operation, then recreate the component (or perhaps delete all the elements and reinsert the component. A second strategy would be to open the component for editing, copy the inner component that I want to use as the trim tool, close the outer component, paste in place, and do a subtract instead of a trim.
It seems there should be an easier way that perhaps I’m missing.
