You are mirroring "Features" that created the body, about a Work Plane and not a cut body. This may work for some models but don't hold your breath for all models.

I should ask, for the sake of understanding what is possible or not, can an existing model be sliced in half, with one half being discarded and the other half mirrored?

Yes.  Slice removing half (or whatever).

Mirror (body, not features) is easiest.

Attach your file here and end all doubt.

I don't doubt it at all... I just want to know how, since I can't find the elusive "slice" command even though I'm certain it's right there in front of my face!

I'll be at my office in a few minutes and will upload the file. Thanks for taking an interest.

start a sketch on the surface, draw a bounding box to enclose all that you want removed/cut and use the Extrude command, with the cut option.

Worked perfectly. Thanks. I knew there had to be a simple, elegant way.

Here's the file. I am a rank beginner and it shows, but I'm getting there. I'm currently doing the CADGorilla tutorials. I did follow Blair's suggestion and successfully sliced the wheel in half and then mirror the body, but here's the file in case you want to look at it.

Thanks again.

In Inventor it is called Split.

Can also be done with Sculpt

or Extrude cut.

Looking at your file I see that you are doing too much work.

You should not have any repeating dimensions for this part and your sketch1 is not constrained.

I recommend you read this document.

Tomorrow I will try to attach example of how I would have done Sketch1.

Ditto blair's and JD's comments regarding basic modeling technique (since I learned from them on this forum, I guess that's a given!).  Assuming that your part is centered on the YZ plane, use the Split tool with the Trim Solid option selected and the YZ plane as the split tool (see Split Tool - Trim Solid.png below).  Then use the Mirror tool with the Mirror Solid option selected and use the YZ plane as the mirror plane (see Mirror Solid.png below).  I think this is what you were asking in your original post.

Thanks JDM.

Yes, I recognize that learning how to be as efficient and elegant as possible is key. I appreciate the tips.

Thanks Sam. That's exactly what I was looking for, the "Split" function, and I knew it was right under my nose. It amazes me how the human brain can prevent the perception of something that is right in front of our eyes.

I took a look at your images and I appreciate your efforts to clarify. I tried it and of course it worked perfectly.

Thanks again to all for your help!
