Axis substitution

[David Czerw Triumph Gear Systems]

I have some flat geo. that I need to wrap around a cylinder. I'm not sure how to set the rotary dia. The angles keep coming out wrong. Any help would be great.

Generally, you use the diameter of the cylinder. If there is some depth to the part, I like to use the minor depth. Then the arcs will show the max. cutter you can use. If you still have trouble, email me your part.

In the top plane - geometry that is at the cenerline of the cylinder will end up at 0

degrees when it is wrapped - it also makes a difference if you wrap cw or ccw - if a line is created in the top plane in the Y direction

with length set to the circference of the diameter then the midpoint of the line will

be located at 180 and 1/4 of the line will be at 90 when the geom is wrapped

[John Summers]

When you're using roll/unroll, always set the parameters to CW,-90 to get the geometry match you're looking for. If you looked at the cylinder in the side view, wrapping CW, when flattened, would go in the +Y direction, and the

side view zero degrees (+Y direction), would end up on the origin, so you need the -90 to get the top point on the cylinder to the origin.

Important: Rotary diameter, rotation direction and not to check Unroll box in the rotary axis or c axis parameter window.
