Once you create a component, you can't access the other bodies until you deactivate that component, and being the only one, you can't do that. (not sure what someone was thinking when they did that) - At least, you can't edit them or do anything with them until you move them into a component, so I guess the idea is that once you have one component, you must move everything into one...
I have 350 bodies (output from a pattern on a pattern (2D array of sorts)) - I want to export the thing as an STL with about 100 of them in one component, and 100 in another and 100 in a 3rd..
So, you select the first 100... and just try to scroll down to the component while you are dragging.. No, you right click on them and move bodies to a SINGLE component.. Oh, it didn't get implemented... Wow, that is a major hole in the design, I've wanted to do that 99.9% of the time that I'm using that feature, I have NEVER wanted to create 300 components from the 300 bodies...
While writing this, I came up with two solutions for my issue... but, you still need an option to create a single component from a set of bodies.
Option 1: Start moving the bodies from the bottom of the list, that makes it easier (still a pain)
Option 2: Back up, make the results of the first pattern be a component, and use the pattern on the 2nd one as a pattern on a component instead of on a body. because there is no way to create the output of a pattern as a component (an obvious feature), you then move all those Components into a component and you have what I'm trying to do... A Hack and slash approach to brute forcing Fusion 360 to do what it should already be able to do...
