    1. Press the PartDesign AdditiveBox.svg Additive Box 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.
    3. Click OK.
    4. A Box feature appears under the active Body.


    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.


    • DataAttachment: defines the attachment mode as well as the Attachment Offset. See Part EditAttachment.
    • DataLabel: Label given to the Box object. Change to suit your needs.
    • DataLength: the Box's dimension in the X-direction.
    • DataWidth: the Box's dimension in the Y-direction.
    • DataHeight: the Box's dimension in the Z-direction.
