I am trying to draw an aircraft propeller with all its twists and changing profiles. I need to make the drawing so it can be exported to a CAM program for use on a CNC router table. Any help would be greatly appreciated.

Hi Larry

My understanding is that the blade of a propeller is similar to a wing with additional pitch and chord thickness distributed across the length of the blade.

Below is a URL that has some basic considerations for a propeller plus a link to a CLARK Y airfoil in DWG format.

Once you create and position your airfoils you could use the skin tool to create the surfaces.

If the ClarkY does not work, a fantastic source for airfoils is :

Once you complete the blade portion I think you would need to design a hub and tip cap.
