Hi Friends! hope everyone is fine....... I am facing a problem of modeling a barrel cam in Pro E. I have to model a cam slot on barrel or cylindrical cam. I have the data of displacement against angle theeta. This cam shall be modelled on 180 degrees on outer peripherry of barrel cam, which means i have data of displacement against different angular steps from 0 to 180 degrees. what i am doing wrong is that when i make a spline using value of theta and displacement as x and y coordinates on a plane tangent to cylindrical surface of barrel cam, it takes value of theta in millimeters and consider it as points of perimeter of circular surface and when i use "WRAP" command to wrap this spline around cylinder, the profile is generated on cylindrical surface for angle more than 180 degrees. Will anyone solve this problem for me?
