# Summary of Masses¶

The SSD task ‘’Summary of Masses’’ generates a `.PLB`

output file
with system overview tables including volume and weight information.

In the task, you can select your desired element types for the summary from the following:

Beam-, Truss-, Cable-elements,

Plane elements,

Three-dimensional solid elements.

For **Beam-, Truss-, Cable-elements**, the output tables give information on the total length
of all elements, the maximum length, the total volume and the total weight.

For **plane elements**, like area elements, the output tables give information on the
total area of all elements, the total volume and the total weight.

For **three-dimensional solid elements** the output tables give information on the
total volume and the total weight.

You can generate mass tables for the element groups, the cross sections or the materials of your project.
