To manually replace the automatically computed values: For example, when unnecessary geometries are removed to improve contact performance or graphic speed or when the CAD geometry itself differs from the actual product design, the automatically computed data, such as the mass or the location/position of the center of gravity, may differ from the data to use in the analysis.

However, in some cases, the automatically computed geometry may differ from the actual geometry of the model. Therefore, it is generally unnecessary to change the location or position of the center of gravity or the mass of the body. For more information, refer to the SpaceClaim Online Help.If you create a geometry or import one from a CAD file, MBD for ANSYS automatically recognizes the geometry and calculates the center of gravity and other properties of the body based on the density of the specified material (e.g. steel), the volume, and other information that you input. Annotation dimensions can also be used to drive model changes. Use the Dimension tool on the Detail tab to create dimensions that measure length, angle, and other characteristics. Click the bottom of the cylinder to create a temporary dimension that measures the height.Creating dimensions for reference is done with SpaceClaim Annotation tools. To create a dimension that measures the height of the cylinder, click the Ruler icon in the Options panel or on the mini-toolbar. For example, when using the Pull tool to change the height of a cylinder, a dimension appears that shows the size of the change: Usually dimensions appear on screen when using a tool to make an edit. Changes to a model are done with tools that use dimensions to define the size of a change. First, determine if you are dimensioning the model to indicate size and proportion or, if you want to drive changes to the model with dimensions.
