I was wondering if the YOST twist IPAS has the ability to define spline twist amounts for the length of the twist axis. I have written my own simple twist program that just linearly twists objects. But I am working on one that you set the twist amount using splines(like in the lofter) and the axis of twist can be rotated to any angle. If the Yost twist can do this then I don't want to waste my time. I used the FFD IPAS (free-form deformation?) to twist an object. I selected the top layer of verts & rotated them 90 degrees, then the next to top and rotated them 60 degrees etc… I made a couple twists and they are very nice, especially because of the spline functioning of the IPAS. linear twists are no good, spline control is necessary. The picture of the twisted 'M' I have from the YOST IPAS ad looks linear, like the ones I produced with my early program. But the ad said there is some kind of bias control. Any clarity on this subject would help. – – — — —– ——– ————- ——————— ———————————-Will
