To Analyze Mass Properties
1. Click
Analysis >
Mass Properties. The
Mass Properties dialog box opens.
Quick is the default analysis type.
2. Click one of the following options:
◦ Solid Geometry—Click to compute the mass properties of the model.
◦ Quilt—Click and select a closed quilt to compute its mass properties.
3. Click in the CSYS collector if it is not active by default and select a reference coordinate system. The name of the selected coordinate system is displayed in the collector. You can click the Use Default check box to select and use the default coordinate system.
The result area at the bottom of the
Mass Properties dialog box displays the result of the analysis. You can view the report of the analysis in the Information Window by clicking
.
|  To clear the contents of the collector, right-click in the collector and click Remove on the shortcut menu. You can then continue to select new coordinate system in the collector to create a new analysis. |
4. ClickOK to complete the analysis orCancel to cancel the analysis. Alternatively, clickRepeat to start a new analysis.
5. Optionally, to save or create an analysis feature, perform the following steps:
a. Click the Analysis tab if it is not selected by default.
b. Select the desired analysis types from the list at the bottom of the Mass Properties dialog box.
c. Select Saved to save the analysis with the model, and dynamically update the analysis while modeling or select Feature to create advanced features.
d. If required, rename the analysis in the box adjacent to the list.
e. Click the Feature tab to create or change feature options of the current analysis, if required. You can access the feature options such as parameters or datum features only when you select a feature type of analysis.
6. Optionally, to customize or edit your analysis, perform the following steps:
a. Specify the material density in the Density box or select a density value from the list of most recently used values in the Density box. The density value is saved with the model. The default material density is 1.
| If a material file is already applied to the model, you cannot specify the material density. |
b. Change the relative accuracy or accept the default accuracy value, 0.000010, in the Accuracy box. You can also select an accuracy value from the list of most recently used values in the Accuracy box. Part accuracy must not be less than 1/100th of the mass property accuracy.
7. Click Preview to compute the analysis. A coordinate system is displayed at the center of gravity in the Creo Parametric graphics window.
| You can specify densities using the Density dialog box. The dialog opens only in assembly and if at least one of the components has 0 density. To assign a density of 1 to the models, select the Use defaults check box. If you do not select the check box, you can update the density to other values. |
