Center of gravity?

133 Views, 8 Replies
11-12-2002 11:34 PM
I have a center of gravity question.

How does one locate the center of gravity on a part? I can get the xyz coords from properties for the center of gravity once my material is selected, but how do I translate that to the actual part?

Is there a symbol or some other identification that would actually show where the center of gravity is on the model or is this something that is detailed in the IDW? Note, we are not ready to detail yet, but are trying to pass on some information to engineering as to where the CG is located.

If there is another thread that speaks to this issue, point me in that direction.

thanks,

john

There is a center of gravity tool but it won't
propagates to the IDW.  The way you can do it is to get the COG from the
properties menu and the use a grounded workpoint and start at the origin and
enter the x,y,z offsets.  This places a workpoint at the COG.  Then in
the IDW you can check the option (get workfeatures) and the workpoint will show
up.

 

This does not dynamically update
however.

Jim this tool is built into R6 on the View
menu.

Would also be nice if the COG in R6 updated as you
drive a constraint....

Try to find out when that part will fall of the
cliff are you? <g>  That would be nice.  I'd also like it to be
able to be shown directly in the IDW (and hence it would update)

Actually Sean yes ;-)...

 

I just went thru the exercise of design a tipping
trailer and Neils COG tool for 5.3 was a god-send, but it would be nice to see
it dynamically update thru the motion. Even just a tick box in drive constraints
to turn that feature on and off would be great....

To all that replied, thanks for the input. Shortly after I posted, our VAR called and we got a few tips from him and were able to figure it out using workpoints.

But as others have indicated, it would be nice if this feature were available when creating an IDW and it would be even nicer if it updated with the part.

Possible wish list item?


Anyway, thanks for the help.
