Duplicate a sketch on the opposite side.

[Fueler]

First time working with mirror, copy/paste or whatever.

Stumbling around in the dark here.

I have an o-ring groove (sketch) that I want to duplicate in the same relative position on the opposite side of the main sketch/part.

I am failing to see how to pull this off.

Can I buy a clue and a how to example please?

Do you really need the sketch? I'd mirror the sweep, see attached.

As you did ask about mirroring the sketch, project the edge of your block then draw a line from the midpoint and use sketch mirror to mirror the rectangle. Be warned, mirror\symmetry constraint do slow the sketcher down so mirroring\copy feature in the timeline is best practice, as my example in the first reply.

Mark,

The sweep version will work fine.

However I am having a problem choosing the mirror plane.

I can do/undo it in your example but when I try it on my original the mirror plane fails with a "compute failed".

Tried the plane and tried the face where it was to be duplicated. Failed

Is there something unseen that I missed? 

[HughesTooling]

On the construct menu there's an option to create a plane between 2 faces, use that and select top and bottom faces of the block.

One more tip, when you run the mirror command leave the pattern type on Face but select the sweep feature in the timeline. Seems like selecting the feature in the timeline automatically selects all faces the feature created.

Choosing the sweep in the timeline was the trick to making it work.

Highlighting the sweep itself was not. 

Thanks
