DISQUS

I am becoming more of a fan of the offset extrusion/cut.

Brian · 4 months ago

Me too! I am using it more and more...it really cuts down on work features.

Chris Serran · 4 months ago

Same here, but I really wish there was a way to edit the offset without going into the feature.

Brian · 4 months ago

Agreed...it would be nice if you could access the offset from a double-click. Enhancement request?

I sometimes add the o-ring groove into my original revolve for the part itself.

Edwin Muirhead · 3 months ago

Great idea comparing methods, though an o-ring groove is usually created as a "revolved" feature in the real world (turned), so shouldn't the CAD model follow this?

As far as modeling reflecting real world procedures; I would not necessarily agree with this. If you modeled everything as it would be actually be made, you would start with a billet and start cutting away - not that there is anything exactly wrong with that, either. I've actually done a few models this way when dealing with structural shapes, and know others that have too.

I suspect that in this particular case, most folks would just model the groove in with the original revolve...

Which option is best if you think you want to modify it later? An o-ring will likely always be circlular but you may want to move it higher or lower in the cylinder.

Brian · 3 months ago

All of the methods but one shown in my post above and including the groove in the main revolve are equally easy to modify with a double click on the sketch or feature or a click and drag with Instant 3D on. The only exception is for the offset cut; AFAIK, that one would require going into the feature definition to change the location.

hi there
my name is jaiswal utsav.i anm a nechanical engineer

instead of using cut,it would be better to make the sketch 1st sketch in such a manner so that when u create a rvolve
it would result in the desired feature ,at once
