Dear Talkers,
Thank you for your comments.
Currently the Corner-Window tool works only with straight walls. I understand that placing a Corner Window into slanted walls can be useful feature and therefore I added a request about it to our wishlist.
It is noted also, that not all Wall Ends are working properly with Slanted or Double Slanted wall types. I have registered it also to the wishlist.
Best regards,
