variable pitch helix?

variable pitch helix?

variable pitch helix?

(OP)
Hello,
I'm trying to make something like this in solidworks:
http://www.esi-group.com/SimulationSoftware/CFD_ACE/images/pump2_lg.jpg

I was thinking of using the loft tool, and using a helix as the guide path. However, the helix's pitch changes from end to end.  My question is, is it possible to create a helix in which the pitch changes continously, or is there a different way I can create such a model? Thanks.

I don't see that feature on my version of SW (2005). What version are you using?

RE: variable pitch helix?

Judging by the date of that post it would probably have to be v2005.  What do you find if you do a search in Help for Helix?  There should be something about a variable-pitch option in there (if this truly exists in 2005--I don't remember--CorBlimeyLimey probably would remember).

The Variable Pitch was introduced in SW06.

cheers

Not in r2005.  Looks like you will have to project a curve to the face.  Will take some calculations to get the correct curve.
