Variable pattern in Pro/E
Variable pattern in Pro/E
(OP)
Hi to everyone,
I there is someone that can help me. I have an impeller with 78 blades and i want to make the angle variable. if you pattern the blade you will have 360/78 you have 4.61535 each angle of blade. No i want to make this gap to vary with a total amplitude 1 degree. Like the attached graph. each blade has a different angle. I am trying to find a relation to add in the pro/E and i failed until now. Every idea will be helpful. Every 45 degrees i have specific number of blades.

RE: Variable pattern in Pro/E
The brute force method is to convert to a table pattern and enter every value by hand but I would hate to do that for 78 blades, particularly if it might change.

This won't generate the angles but it would be simpler. Now if only Dimensions could be reference patterned.
