Hi bemfarmer,

So probably what you would want to do for a cross-section like that is to think about creating it by cutting a base shape.

So you'll start with just an initial solid tall cylinder for the main body, then build 2 tubes that follow a helix path twisting around it, and then use boolean difference to cut those tubes away from the main body shape.
