Tidying up.

When the Replicator did its stuff, it created a separate object for each wedge.
That may or may not be what you want.

To merge all the objects into a single object:

1. Switch to Object Mode if necessary.
2. Select everything (easiest done by clicking "All" in the toolbar above the Front view).
3. Go to Object->Menu->Merge

Done. A single object. But we're still not quite finished.

Remember when we snapped together the vertices to make a wedge? Those vertices doubled vertices were also replicated.
Plus, if the Y-translation for each wedge was exact enough, the point where will contain 4 identical verts.
To rectify, go to Menu->Object->Optimise Vertices...

And that's about it, really.
Save you file (if you haven't already) and File->Export in a format of your choice (I usually use .obj).

You may want to add a cylinder, move it so it's centred on the Y axis and scale it for a centre pole.
If you do do that, I strongly suggest giving it a different colour (from the strip down in the bottom left). This will make it a lot easier to add separate materials/textures later.

If the object is going to be used in Poser, you may need one extra step.
Fire up Poser and import the staircase. Is it "bloated"?
If you have Poser 6, then you may be able to get rid of this using the crease angle etc.

If not, then Run the .obj through Steve Cox's UV Mapper and split Verts (remember to save under a new file-mane).

It's taken me far, far longer to write all this and illustrate it than it did to create the staircase originally, but that's to be expected.

I know it's all very simple stuff, but I was aiming it with the "absolute beginner (in AC3D)" in mind.

Hope you liked it.

Cheers,
