Not the native Trim tool. For several years I’ve been asking to have the Solid Tools changed so that they don’t convert components to groups. Any other tools used to edit components result in all instances of the component getting edited but the Solid tools don’t. It seems like a huge inconsistency in their operation.
There are a couple of options, however. Jim’s Trim and Keep which is available through the Sketchucation Plugin Store (at no charge) and Eneroth Solid Tools from the Extension Warehouse. I mostly need the Trim tool and use Jim’s plugin because it operates in the same order as the native tools. Eneroth Solid Tools reverses the order. Both leave you with components.
One thing to be aware of with Jim’s Trim and Keep is that it leaves the original version of the component in the In Model library. This is useful if you need an untrimmed version later but if you don’t, you should run Purge All to get rid of the extra copies.
