Presently the program is configured to analyze trusses which have less than 80 members, less than 40 joints , and less than 20 different support forces.
Do NOT calculate support forces and enter them as known forces, the program will (and must) do that for you.
In order to make changes or to enter additional data into a
particular box move the mouse cursor to the desired spot and click.
A blinking vertical bar will appear which you can move within an

You may use the "Back" button of your browser to return to this document and will find all entries in the boxes still intact. You may then apply changes to the entries for another round .....
