Different values for the creation and editing of elements can be entered or calculated with the calculator. These can be e.g. distance, diameter or width. The input is made by clicking on the buttons or using the keyboard.

The information line indicates which information is currently to be entered. These can also be several values one after another.

The functions of the calculator are similar to those of a pocket calculator. The input values appear in the value display area and are confirmed with the Equals sign button, the right mouse button or the Return key. Once the last required value has been entered, the calculator is automatically closed.
