extrude cyclone
 

Hi
I have a problem with extrude the top of the cyclone. I can not draw a spiral angle (Appendix 1 - so it should look like).
As Annex 2 send drawn by me in DesignModeler the cyclone with the traditional spiral inlet (+ Appendix 3 - jpg).
As Annex 4 I put something about it in a spiral that DesignModeler - but only as lines drawn.

If anyone has any ideas, I would ask for help.

Thanks in advance.

Regards

the only function capable of doing that in designmodeler is the sweep function. if you want the spiral, you need to turn on "twist".
