Hey I'm trying to model a car for class and I need help. I'm trying to use the birail action and it's not working right. Below is a picture of what I'm trying to get the birail to work. There are 5 curves and all the end points align with each other (using ctrl+c or v to snap align them). What am I doing wrong?
Make sure you are using the Birail 3+ version of the tool, and make sure you select the two rail curves last. If you're selecting in the order shown in your screenshot, Maya thinks you want to sweep curves 1, 2, and 3 between the 'rails' 4 and 5, which won't work.
