Center of Gravity help
(OP)
is there a way to add densities to all materials in an assembly and have proe give the center of gravity?
thanks,
Chris

RE: Center of Gravity help
A mapkey might make this a bit more bearable if you have a lot of parts to do this to.
The Mass Properties analysis will tell you the location of the CoG relative to the assembly's default coordinate system (unless you specify another Csys to use).
RE: Center of Gravity help
We assign material files (on a network drive) to all our parts. Done with a mapkey when creating a new part.
When doing this, this also helps out the anaylsis guys.
To create material files we use matweb website.

Still would be alot work though. :(
BTW, we use the condition line to be called out in drawings for material using a paramter and a relation.
MATERIAL=material_param("CONDITION")
al_aly_6061-t6.mat file
MATERIAL AL_ALY_6061-T6
