OK - this is a big one... I am using walls way more these days, but the curved walls are still a really big problem! I don't know what to suggest but there must be a way that they can be made to integrate more smoothly...
If you want to see some of the problems I have had with them, I can send you a recent file. More and more clients are requesting "organic" shapes (curves... ) so in order to use the walls this is really imperative.
Thanks
