The Sumator tool allows you to easily calculate the total surface area of any indicated geometry and the total length of the indicated edges

General Usage Instructions

To get the sum of the surface area of the selected geometry and/or the total length of the selected edges, before starting the tool, pick the faces and/or edges of interest using standard Autodesk® Inventor® tools. After starting the tool, a window with the entire field or total length will be displayed. In the window, it is also possible to quickly convert the results into 5 different units.

If you need to count the area of most surfaces, or the length of most edges in the model (only Part Environment), you can use the "All faces" or "All edges" tool. It is sometimes easier to deselect a few unnecessary items than to select almost all.
