Dynamic Mass Properties

Hi,

Is there a way to use the center of mass coordinates to create a point
(that would become evantually a sphere) that will be dynanically updated
(new CG) each time that the geometry of my part or solid bodie would change?
Thanks for your help.

Pablo,

 

The only way I know of is with a macro feature. I haven't really done
enough with macro features to tell you exactly how, unfortunatley.

 

do you know visual basic or c++?

 

Hi Sean,

I know very little of visual basic and nothing about C++, but give me
the basic ideas and I'll see what I can do from there, thanks.

 

Pablo,

Do a google search on this user group. Type in "CG Macro" and you will
several different versions. They should provide for the basis for
further customization if they don't do what you want.

Hello Pablo,

Try this:
http://home.comcast.net/~muggs828/solidworks/point_on_mass_center.zip

Open this and start suppressing features to see the CG update. The macro and
the model must be in the same folder, and of course you'll need to be
running SW2003 or newer version of SolidWorks, because it uses the Macro
Feature capability.
BTW, I would love to give credit to whoever wrote this macro but I got it
from someone else, and there's no name in the macro. So if you're reading
this and this is your macro, thank you, I've benifited from it.

HTH,
Muggs

 

If I remember correctly, Mike Wilson did some Macro Feature work back when
it came out - might be his.
