Not sure why no one answered this. The Turned Profile gadget input is a vector. The vector start and end must have the same y value. An stl file is not the correct input. There are some gotchas in that gadget. Make sure that you make a model before trying the real thing. I've had better luck with the molding path generator. Start with the wrapping profile gadget before starting a new drawing. The output will generate a path that takes the Y values and changes them to "A" depth and rotation values and x-axis values according to the bit step over. I use Mach 3 and my post processor needs to support the Y to A translation. Fortunately it is supplied with the Vectric software. The Turned Profile Gadget creates a raster path down the x axis and rotates the part according to the bit step over.
