Drafting the center of gravity
Drafting the center of gravity
(OP)
Is there a "true" way to draft the calculated center of gravity? I've only seen it on one other print and I doubt the method I saw is a part of any ANSI spec (or equivalent).
On a side note...
Using NX6 (or NX whatever version), does anyone know of a way to automatically calculate the Mass, Inertia, and a Center of Gravity and add a call-out onto an assembly print that automatically updates each time the part is changed?
Thanks

FYI...
The question about how to draft the CG came to mind after I asked the "Side note" question in another thread http://www .eng-tips. com/viewth read.cfm?q id=253382& amp;page=1

It was a circle with a cross hairs through it and two diagonally oposed quadrants shaded. Something like shown on sheet 2 of the below link.

The CAD question would be better asked in that forum, though ewh may be able to help you out. I know Solid Edge can do it.
KENAT,

There is an old baseball joke about someone asking about the bunt signal and being told that the coach will cup his hands around his mouth and scream "BUNT!"
Even if you do know what the symbol for CofG is, will anyone else? At some point, you have to type it out.
RE: Drafting the center of gravity
Drawoh also brought up a good point, that it really should be spelled out somewhere if you want others to be able to use it. Depending on the application, it may or may not be necessary. For example, if it appeared on a drawing for manufacturing counter-weights to get the CG where you wanted, it would probably be pretty clear what the symbol represented to anybody that needed to know.

I just don't want to make it look like a 9 year old put it on there with Crayons... I will at least use markers!!
The CG symbol looks like the way to go.
Thanks!

The customer drawing showed the CG as a point (cross-hair) with referenced x,y dims.
