To Use a File for Assigning Mass Properties
This functionality lets you assign mass property values by using a file. If you use this method, you have to specify values for all the parameters listed in the file template. If the file is incomplete, the system does not generate a report.
1. Click File > Prepare > Model Properties. The Model Properties dialog box opens.
2. Click change in the Mass Properties line. The Mass Properties dialog box opens.
3. Select Fully Assigned as the source for mass properties calculation. Type the values for all the parameters. You can save the values to objectname_amppar.dat file in the current working directory.
 
* Alternatively, click and browse to the objectname_amppar.dat file. The values in the file are loaded in the Mass Properties dialog box.
4. 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.
5. Click Close when finished viewing the report.
