Have a shaft which needs some grooves cut in it so as to place rubber o-rings.The 2 grooves at each end are fine but how would i make 2 grooves in the middle section ( sketch 3 & 4 ) travel around the shaft in a wave shape.Picture attached hopefully gives a better idea

Like this?

Nice Maria

If i want to add o-rings how would you add these.Is it best to add the o-rings at the part stage or can i add these within the assembly.

Cheers

Hi

In my opinion its more easy if create all in part environment using the Multi-Body technique.

So....during Sweep feature, check que New Solid to create a new and independent body.

Then...with Combine tool create a Boolean operation (the target is: use the new body to perform a cut in the "shaft" body)

Now you have 2 independent bodies. You can perform Move Bodies to check what you get with the Combine tool.

Then...delete from the browser the Move feature to oring back to original coordinate. 

Finally export this as assembly. Go to tab Manage \ Make Component.

Good luck

Thank you Manuela

That work very well.Great help

I have a final question .I tried doing the same steps you showed for the Revolution 1 but it did not work.Does this need to be a Sweep feature for this to work?

Thanks again

You welcome.

No... it is not necessary to be sweep to work.

The error occur derived from the modeling hierarchy. You not started modeling thinking about this type of multi-body modeling.

It is preferable delete the sweep feature...check new solids as you want...and then create the sweep orings.
