extrusion and body intersection problem

hi, I have a problem with the extrusion of this component. I created the snail through the boundary blend, now to create the straight part of the inlet I'm making an extrusion but I would like this not to intersect the blend so as to leave a void at this point:

Create the straight section using a new body. The "snail" will be one body and the straight section another body. You can then use the Boolean operations on the bodies to get the desired result. This assumes that the bodies intersect cleanly.

    Since the snail is empty when I use Boolean operations it only removes the outline of the intersection and the cap remains. Maybe I'm doing something wrong?

    Without seeing how you built the model it is hard to say what the issue is. If you post your model here someone may be able to troubleshoot it.

    If you are designing a volute for fluid handling, I would suggest using curve from equation to generate the sweep trajectory and a variable section sweep to make the "snail". I would also build the wetted surface of the volute first using surface modeling and then add the thickness to the outside. You can think of this as defining the fluid domain volume before adding any solid geometry.

      Take a look at the steps that I posted in this thread (last post in thread) for an example of how to model a volute shape.
