How to use

 * 1) Press the  button. Note: the Additive Box is part of an icon menu labelled Create an additive primitive. After launching FreeCAD, the Additive Box is the one displayed in the toolbar. If a different primitive is displayed, click on the down arrow besides the icon and select Additive Box in the menu.
 * 2) Set the Primitive parameters and Attachment. TODO: add Attachment page (Part_Atachment? PartDesign_Attachment?) and link to it here
 * 3) Click.
 * 4) A Box feature appears under the active Body.

Options
The Box can be edited after its creation in two ways:
 * Double-clicking it in the Model tree, or by right-clicking and selecting Edit primitive in the contextual menu; this brings up the Primitive parameters.
 * Via the Property editor.
