Hi Michael,

Sorry if it has allready be asked, but is it possible to create a little scipt to center (move) a selected entity (surfaces, solids, curves) to the world origin ?
(not sure if the request is clear :))

Hi PaQ, yup this is pretty easy to do now since a couple of betas ago I added some stuff so that scripts could access an object's bounding box.

Take the attached file CenterAtOrigin.js and copy it to your v2's \commands sub-folder.

Then set up a keyboard shortcut with CenterAtOrigin (note, no .js at the end, and no script: at the start, just that plain name) as the command part and that should do it.

Please let me know if it does not work for you.

EDIT: Updated attachment to new version that centers object at the cplane origin if there is a custom cplane set, otherwise at world origin.

Perfect Michael, thanks a lot !!!!!

Extremely useful.

Thanks Michael (and thanks to PaQ for asking this... Hehe)

Hey happy it's handy for you Schbeurd :)

Hi Michael,

Just a other question, is it possible that the 'center at origin' works with the cplane too ? so the selection is center to the cplane origin when you're using a cplane, or to the world when cplane is off. I hate to fell like I'm at in a scipt-supermarket, but it's really not my cup of tea, so thanks for you help.

Hi Michael,

Thanks very much for making this & Thanks to PaQ for requesting it.

FWIW I'm using F4 as my keyboard shortcut so it'll match up for use when I'm using Rhino.

regards Colin

Yup, it's only a tiny adjustment to make that work.

I've updated the attachment to that previous message
(http://moi3d.com/forum/index.php?webtag=MOI&msg=2409.2)
to work like that now, so just copy that new version over top of the previous one.

haaaaa really cool, thanks for taking a bit from your time to this script Michael !

I am trying to run this script with a shortcut and the selected object disappears.

When I run it via the script menu at the bottom, the object is centered as expected. Any ideas what could be wrong?

edit: I remember it was working fine at some point- no idea what changed

Is the object too small to see? , or is it located outside of the viewing area?

Hi nameless,

I can't repeat the problem over here, does it happen just with a particular object? If so can you please post a .3dm model file with the object in it?

Hi Michael,

Thank you for looking into this. I found what the problem was- Numlock was not pressed when I tried it, so it somehow registered the period as a coordinate or size input.
Trying again with Numlock on and the script works, object is centered just fine.

Apologies for wasting any reader's time with this. :\
