I want to explode a pattern with loads of parts (that exist in a pattern feature), when in options i try to add the pattern to the parts to explode it doesnt let me. Do i have to individually click them either in the model view or tree??
I don't have an exact answer to your question but I usually work around this issue by exploding some main part away from the pattern of parts.
Or I run auto-explode and pray that it works close enough to how I want it to so that I only have to tweak the results.
Otherwise I've always had to indvidually click them.
