Farmfield Posted July 10, 2016 Share Posted July 10, 2016 Yeah, I managed to figure that out - I think the term is pretty misleading, it really is an alignment more than anything else. Now, still haven't figured out how it's set up - and why. It's about coordinate space, I'm guessing, using the subnets. Need to dig into that more but I've been stuck with other stuff.

This solutions are pretty cool by the way. Edited August 15, 2016 by Butachan Quote Link to comment Share on other sites More sharing options...
Farmfield Posted August 15, 2016 Share Posted August 15, 2016 So I just painted myself into a similar corner, trying something similar, reshaping one box to another - and got as stuck as I did with this. I created a thread about it here, if anyone wanna take a look at it. Quote Link to comment Share on other sites More sharing options...
