I fcking hate Maya,every 2min i run into problem, that i have no idea how to solve it. I want to do append polygon or bridge these edges. In this picture i use Bridge, and this comes. And in this, i use append tool,
What claydough said. Also don't use bridge for 2D planes it will screw up and sometimes you won't notice. It's tempting to use bridge because it's faster, but only use it for connecting 3D holes, use append to polygon for situations where you are wanting to draw a quad between only two edges. Also if you're really stuck…
looks like a normal direction problem....try highlighting the faces that contain the edges, select normal>set to face and then try the append again....I often get a twist from maya's bridge tool so I never use it anymore. hope that helps
first i am going to call you out as a "noob" for working with backfaces on (someone whos first sentence of a thread includes the word "hate" deserves that ) and than i am gonna agree with seth this looks like your bottom plane is normal flipped which you probably would have noticed if you didn't work with backfaces on ...…
