To Assign Parameters and Generate a Mass Properties Report
This functionality lets you assign alternate values to certain mass property parameters. The system then generates the report based on these assigned values. If some of the values are not assigned, the system uses the default parameter values derived from the model geometry.
1. Click File > Prepare > Model Properties. The Model Properties dialog box opens.
2. Click change in the Mass Properties line. The Setup Mass Properties dialog box opens.
3. Select Geometry and Parameters as the source for mass properties calculation.
4. Select the coordinate system to be used.
5. If you want to change the default density, type a value in the Density box. If the object is an assembly, the Density box is empty. If you do not specify a value, the system will prompt you for densities of component parts at the time of generating the report, and calculate the assembly density as the average of component densities.
6. To specify the alternate parameters, type the parameter values in the appropriate boxes, where desired. If you do not specify an alternate parameter value, the system will use model geometry to compute the reported parameter. Follow the link under See Also for a complete list of mass properties parameters.
* If you have previously specified alternate parameter values through the Parameters functionality, these values appear in the appropriate boxes. If an alternate parameter is driven by a relation, the appropriate box is grayed out and you can not type a value.
7. Click OK when finished, to close the Mass Properties Parameters dialog box.
8. Click Generate Report. The system calculates the mass properties, displays the results in the Information Window, and saves them in a file objectname.m_p in the current working directory. You can use the Edit command in the Information Window to edit the file, or use the File > Save As command to save it under a different name.
9. Click Close when finished viewing the report.
