Mass-Inertia Properties

Previous pageReturn to chapter overviewNext page

This command allows calculating mass-inertia properties of the selected operations.

 

The command "3MP: Mass-Inertia Properties" is called via:

Icon

Ribbon

Measure→ Measure → Mass Properties

Keyboard

Textual Menu

<3MP>

Tools > Geometry Analysis > Mass Properties

 

Upon entering the command, the following option is active by default:

       <B>        Select source 3D operation        

It allows selecting the operation, whose properties need to be calculated.

To calculate the properties that depend on all existing operations, do not select any operations or use option:.

       <A>        Select all solids

This is the case if you need to calculate properties of an assembly model composed of several bodies. The bodies may even have different density. The system will account for that.

To cancel selection of all operations, use the option:

       <F>        Cancel Operation selection        

If necessary, calculations can be done relative to a local coordinate system that can be selected by the option:

       <L>        Select LCS        

To cancel coordinate system selection, use the option

       <K>        Cancel LCS selection        

If no target coordinate system is specified, the calculation will be done in the global coordinates.

Upon selecting the operations and the coordinate system, finish the input. Upon finishing the input, the "Mass properties" window will be displayed.

The parameters "Mass units" and "Linear units" allow setting up the desired measurement units.

The computational accuracy can be defined in the respective input box or set by the provided slider.

If you press the button [Compute], the dialog will display the calculated values of the parameters that are represented in this dialog box.

The button [Export] allows saving the calculation results in a text file.

The button [Exit] closes the parameters calculation window and brings you back to the mode of selecting bodies and coordinate systems.
