Question

Center of Gravity in Drawings

Considering that the position of the CoG can be calculated using the mass properties function, is there a way that the CoG can be shown in a 2D drawing and be dynamically updated as changes are made to the part/assembly?

I know I could display the CoG csys and then manually lay a symbol over the top but I'd like this to be automatic.

Analysis --> mass properties

Click on the Preview button.

Ensure that the Feature Option is selected at the bottom.

The following pictures should explain.

Having done this, you may choose to have a POINT at this COG which would update dynamically at every REGEN.

    How do you turn on the CSYS_COG or PNT_COG as they are greyed out?

    I can create the feature as you state above but the resultant feature has no tangible properties to which I can attach a drawing symbol. In fact I can't find where the feature sits within the model as it does not create any visible reference when it is highlighted in the model tree.

    Same question as asked here: http://communities.ptc.com/message/174277#174277

    Hi

    Those greyed icons (CSYS_COG or PNT_COG) can be activated if you have Behavioral Modeling Extension (BMX)

    Check your license

    Hi

    You have asked for 2 things

    1.Weight-

    a)You can use system parameter pro_mp_mass to make your user parameter and use it in drawing, or family table

    b)You can make a feature parameter in mass properties just like xcog,ycog ang zcog stated above; and then use this feature parameter to make your user parameter and use it in drawing, or family table

    2.COG

    You can use the feature parameters xcog,ycog ang zcog to make your user parameterand use it in drawing, or family table

    Regards
