Catia Valve

Herewith i enclosed a valve part
Proe file - finished stage,
Catia file - Semi finished can be continued,
IGES - - finished stage,

In Proe there is one command called Variable Section Sweep which can capable of sweep only one section along the `N'no. of guides and 1 Spine (Center curve).

I tried this by using Multisection solid the Skecth 3 (Radius 39 mm circle) as Section, Section 7 (Center curve) and Section 6, 8, 9 & 10 as guides. But i can't get the result. If anybody know that how to do this, kindly guide me.


thanks in advance

After taking a quick look at the IGES file, I would like to propose a much simplier modeling approach that results in this final design:
valve.jpg

This was achieved by creating a Shaft based on Sketch.10 in a separate body, and the splitting the Shaft with the profile in Sketch.8. Roundoff the sharp edge. Then do a Boolean Add to combine this shape with the rest of the valve.

Thilag,

Based on the curves you have, I don't think you'll be able to use a Mult-Section Solid for this. I suggest you try a Sweep in the Generative Shape Design workbench. (the CATIA Sweep is probably very similar to Pro-E's Variable Section Sweep)

I attempted to use a Sweep myself. But I had problems with the top profile curve and the way it dips down below the center curves. Please check your data.

It would also help to add a ending profile in the center of the main valve body.

Looks good, and the Multi-Section Solid worked! Did you add Spline.1 at the end?

Thanks for sharing the solution.
