Re: Does anybody know how to create this model ?

My quick stab at it.

I used extrusions, rounds, then shelled.

I'm sure there are many other ways to tackle this, here is one.

Re: Does anybody know how to create this model ?

I'm going to assume you want it to be nice smooth transitions.....so, a day in ISDX or 5 minutes in T-Slpines for Rhino - a very cheap CAD program where third parties make very useful plugins - and export a STEP file to Creo.

Put t-Splines as a search into youtube and see what comes up.

I wish Creo could do it easily, I was hoping T-Splines would make a Creo plugin at some point in the last 5 years, but guess either Creo won't let them or its not financially viable as most Creo users don't care much about the surface quality.

I used curves and the style feature to create a surface model.

If the surface quality is important, you can use the freestyle tool. However, you can find problems to set the exact diameter due the lack of control.

Re: Does anybody know how to create this model ?

I would say yours is the best so far -assuming that the requirement was for circular apertures.....the middle of the surfaces are not that great though when you analise with reflections, but probably good enough for the part Mani needs. I think that is just what happens with N sided surfaces in Style / ISDXsurface_relections.JPG

Re: Does anybody know how to create this model ?

I was surprised how good it came out on the first try.

Re: Does anybody know how to create this model ?

I was thinking in this direction as well.  The nice thing about Creo 3 is that you can merge the freeform to existing geometry.

This means you can manage the diameter and even the location of the join from the origin.

I have also come to trust skeletons (simple curve geometry) to guide the freeform scaling.

Keeping things symmetrical is the biggest hurdle.  The scale feature is most useful.

Re: Does anybody know how to create this model ?

Mani, do you have the export file (step or iges) of the original? that you can attach?  Use the advanced editor.

Re: Does anybody know how to create this model ?

I used the N-Sided patch tool which worked quite well, actually.  I was surprised, I've not had a lt of luck with it.

I assumed that the part was symmetric but that the outlets weren't all the same diameter nor the same offset.  Outlets on each axis can be changed independently and the offsets can as well.  Part is pretty flexible, but the shape gets a little odd at extremes.

Creo 3 part attached.
