Alright I'm on this page of the tutorial:

https://www.gmask.com/tutorials/wrx_t.../Book009.shtml

Whenever I try to bi-rail the curves I keep getting a "birail surface computation failed. Any ideas why that would be the case?

Make certain that the end points of your curves are snapped directly to each other. It won't work if not.

Yeah i had the same problem. Just hold down the C key when you place the first and last points of the curve.

I checked this like 10 times, and it still won't work. I'll take a screenshot when I get home. When I do a Bi-Rail 2 it works fine (leaving out the middle profile curve). That must mean that it's the middle profile curve that has the problem right?

It gits kinda of hard to get used to. You have to get the point close to the line and drag it on to the curv while pressing c. It might take a couple times but it works.

Actually all you have to do is select the CV or edit point you want to snap to the curve. Then hold down C and click the curve you want it to snap to.

I found that out the hard way.

Have you did a rebuild on the curv. Make the curvs even. Or did you have nurbs hidden. If its still not worken then I do think the lines aren't connecting.

Other thing are you selecting the three curvs across the trunk and pressing enter then selecting the top and bottom curv and press enter again. Thats how you use brail.

hope that helps

Yeah I know I used birail the right way....I didn't rebuild the curve, and I've checked if everything is touching. I just want to figure out why this in particular wouldn't be working?
