Zoom to Fit Not Working With Isometric View

[sloth4z]

I was messing around with the attached part and zoom to fit is not working properly (see picture). Isometric view is not centering the view, and is instead pushing my part to the top right of the screen. This first linear pattern is pushing the model to the right side of the screen, and the second is pushing the model to the top of the screen. Does anyone know what is causing this and/or how to stop it? I have installed SW2008 SP1.0 onto Windows XP, with dual moniters and NVIDIA Quadro FX 1300 video card.

Make sure you're using the proper drivers for your video card, though I don't think that's it. It's more likely that you have an entity, or entities, out in space that's causing it to happen.

I agree with Jeff ... and to clarify, the entity would be in the seed block. It could be a wayward point, a very short line, a tiny circle, an axis or oversized plane, or ....

It pushes it a little to the upper-right for me. Don't know why. For front, right, top views it is centered.
I don't see any other geometry that would do this.

It is possible that there is some unaccounted for entity that happens to only show it's presence in the ISO view, though that is unlikely. Where's the 0,0,0 point?

Fit to screen uses all geometry in the model including over-sized planes and sketch centerlines. Make sure these are not sticking to far outside of the model.

I'll take a look at your file and see. It looks cool.
Did you happen to use an Imposometric View to create it?

It is because the Part like I expected is just an optical illusion but I have a solution.

It turns out that the fit only applies to shown geometry so I created a 2d sketch to do the same thing your 3D sketch did. Then showed the sketch and made it the same color as the background.
I also centered the origin for you using 2/3 ratio

I don't think it is any stray entity causing this. Here is another part with the same results. I didn't even use any dimensions or reference geometry. I think it's a flaw in the program. I've never noticed it before so it might be a 2008 issue.

fcsuper: the origin of the original part is in the center of the right most cube.

mjcole: thank you. the triangle is somewhat famous and there is even a name for it (though I can't think of it right now). Your method it is pretty clever. I'll keep that trick in my back pocket if it ever becomes critical.

That is really strange. I opened your part and it behaved exactly as you stated. I then recreated the part but it worked as one would expect.
I wonder if it isn't something in your part template itself? If it were a graphics issue, then it shouldn't migrate between systems. Very strange.

sloth4z ...

You are correct (no stray entities).

After creating your last triangle in SW07;
When viewed flat on, it is centred in the screen as expected. Any XXXmetric view pushes it to top-centre. I have no idea why it should do that.
