How can I do a linear+circular pattern for a shredder machine?

I am working on a shredder machine project and I have a problem. Currently, I need to put 36 blades with an angle of 10 degree between them on an axis and I have no idea about how to do that in a simple way. I dit it on SolidWorks using the linear pattern with angles. Can I do this at inventor ?

Accepted answer

You can't pattern the blades directly in a helical pattern. Create a shaft with some feature patterned in on a helical curve. Constrain the blade to the shaft in the assembly. Then pattern the blades selecting the feature pattern of the shaft. I used a patterned hole on the shaft for simplicity. You would probably use a keyway or something similar.

You would likely have to do something like this on the real assembly anyway.

The finished assembly using the shaft to pattern the blades.

Thank you all! You helped me a lot !
