Dimension center of gravity (COG)

You can indicate the location of the center of gravity (COG) in single-part, assembly, and cast unit drawings by creating COG dimensions and a COG symbol at the center of gravity. You can also create COG dimensions in section views. COG dimensions will be automatically updated if the single part, assembly, or cast unit changes. The COG dimensions can also be cloned.

Limitations:

  • If you copy or link a drawing containing COG dimensions to another drawing, such as a multidrawing, the COG dimensions will not be copied.

  • You cannot create COG dimensions in general arrangement drawings or multidrawings.

  1. On the Dimensioning tab in an open drawing, click COG .
  2. Modify the options as required:

    • In Create , select Symbol to see only the COG symbol, or Dimensions to see only COG dimensions. To see both, select Both.

    • In Dimensioning , select to create Horizontal or Vertical dimensions, or Both.

    • In Dimension attributes , you can load predefined dimension properties.

      The appearance settings (size, color, etc.) of the COG dimensions are read from the dimension properties file you load in Dimension attributes. To create and save dimension property files, on the Drawing tab, click Properties > Dimension. For example, you may create a special COG dimension properties file to change the color or arrow type, and load the saved properties in Dimension attributes.

    • In Symbol Options , you can change the Symbol file in use and the symbol you want to use for COG, and load predefined symbol properties.

      You can access the symbol options only if you have selected Both or Symbol for Create. The appearance settings (height, color, etc.) of the symbol are read from the symbol properties file you load in Symbol attributes.

      To create and save symbol property files, on the Drawing tab, click Properties > Symbol . For example, you may create a special COG symbol properties file to change the color and height of the symbol, and load the saved properties in Symbol attributes.

  3. Click OK.
  4. Pick the first point to specify the origin of the dimensions.

    The origin is the point from which you want to measure the location of the center of gravity. This point must be located within the view frame.

  5. Pick the second point to place the dimensions.

    This point may fall outside the view frame.

    The example below shows the created dimensions.

  6. When the dimension is selected, handles are shown at the dimension origin and the dimension location. You can drag these handles to adjust the origin or the location, or move them using the standard editing commands.
