I had the same issue with my TTCombat stuff. I solved it by buying some Wargames Tournaments walkways and ladders. They don’t clip like ttc but they rest on top. You can see one going diagonally in post #17.I do need more walkways and ladders though.
Which could work, but you might have to work out what wedges you need.What I've found though is that the angles on the triangular floor sections are not condusive to linking the sets together outside of choosing one long edge only.
I'm trying to have the two tallest platforms as separate parts joined by the smaller pieces. The angles on the sides of the cloudbuster makes even a mirror setup not clip together.Not sure I'm picturing this right, are you trying to make a half octagon with the 2 parts or are you wanting to stack one on the other?
