Hi Everyone,
I'm sorry if i missed the place for placing this question. So a have an Assembly/Part on which i need to have a point at the center of mass. That point has to be referent point for 3D sketching. I tried using equasions when dimensioning the point i've added, but the problem I am having is that SW can't work with negative dimensions, and if I put ABS (absolut value) in front, than it doesn't change sides of the plane if the center of the mass is changed. Is there a way to do this without Macro ? And if not, can someone please point me to the macro I can use in this situation.
THANKS EVERYONE FOR HELP
Most of the macros I have seen do exactly as you say and create a 3d sketch with a point at the CG but do not update when the CG changes. I am attaching a macro I found (I didn't create it so I can't take credit for it) that creates a macro feature that will automatically update every time the features above it alter the CG. I had to alter the code slightly to make useful for your situation (there was some options that forced to feature to be at the end of the feature tree thus not allowing you to use the sketch point that it creates as a reference because the software will always push the feature and sketch to the end of the feature tree).
But beware that, as with the workaround I suggested and if this functionality ever becomes available, if you add any features (i.e. cuts, holes, etc.) after the reference point you create that would alter the CG that will not be reflected in the reference point that you are using. The sketch points are created when the model is in a state where those features don't exist and the CG reflects that.
