Inserts a subtractive box in the active Body. Its shape is subtracted from the existing solid.
On the left: active body (A) shown in grey and subtractive box (B) shown in transparent red; result on the right.
Usage
There are several ways to invoke the tool:
Press the Subtractive Box button. Note: the Subtractive Box is part of an icon menu labelled Subtractive Primitive. After launching FreeCAD, the Subtractive Box is the one displayed in the toolbar. If a different primitive is displayed, click on the down arrow besides the icon and select Subtractive Box in the menu.
Select the Part Design → Subtractive Primitive → Subtractive Box option from the menu.
The task panel opens.
Set the parameters. introduced in 26.3: If the Show interactive draggers when editing featurespreference is selected (default), parameters can be adjusted with interactive gizmos in the 3D View.
The Box can be edited after its creation in two ways:
Double-clicking it in the Tree View, or by right-clicking and selecting Edit Primitive in the context menu; this brings up the task panel and (introduced in 26.3) the interactive gizmos (if enabled).
Sets the boolean operation used to combine the box with the base solid. introduced in 26.3
Subtraction (default): the box removes its volume from the base solid, as in previous versions.
Common: the box keeps only the volume shared between itself and the base solid, discarding everything else.
