C0G in an assembly drawing

[prohammy]

All,

I have a drawing question (from my team leader) that I am not sure which direction to take. Any help/advice will be appreciated.

I have a top level drawing of the machine that this company makes. My leader wants to put the CoG of the machine on the assembly drawing (and dimension it, for customer/lifting information purposes). My problem starts, when I look at the machine (roughly 20,000 piece parts), the overall weight calcs from ProE are out by 50% (turns out my predecessors never bothered with material properties and weights, they were all new users) thus making ProE's CoG calc useless. The company have a position that they have 'found' for the CoG and this is what they want attached to the drawing. I tried inserting a drawing symbol for the CoG, but was unable to dimension to it.

What else can I do????

Cheers

Kev

PS The other option I have thought of is to put and very small cylinder/sphere in the assy model that I could dimension to, but this is my last resort

Why not to put a POINT in the assembly model? Then you can show it in yu drawing and add dimensions.

Thanks Hora,

Sorry I forgot to cancel the request, it came to me from another forum. I am presently feeling pretty damn stupid.
