How to make a mold with a complex (twisted - non planar) partying line with the two half molds needing to match perfectly against each other. Notice that you shouldn't have something cutting the way between the partying lines of your body. For example if you have a wing with a high curvature and you want to make a mold of this, this method will not work. This is why we gonna to watch several me...
