Basically I’m making a greenhouse. This is one end of the building and it’s symmetrical on the other end. I feel really thick atm, because I’ve been doing lots of building and everything lately, but this roof just isn’t working for me.

I want to put sloped greenhouse roof tiles around the edge, and then just flat greenhouse ceiling tiles in the middle.

I tried placing a thatch ceiling with the angled thatch wall on top, to snap on the sloped greenhouse roof. That worked fine. But then once I destroy the thatch, my sloped roof tiles just break too.

Can anyone help me fix this so my sloped greenhouse roof tiles snap onto the actual walls?
