I'm trying to model a hose that curves through 3 dimensions. In the past, I have created a sweep, using the blue spline as the trajectory but this only produces flat (2 dimensional) curves. I created some points at varying X,Y and Z positions and through these points, I made a datum curve that was close enough to what I wanted. But the sweep won't recognize the datum curve as a trajectory. Can someone help me with this or point me to a tutorial on how to do this? Thanks. Peter
