Inserts a subtractive wedge in the active Body. Its shape is subtracted from the existing solid.

On the left: active body (A) shown in grey and subtractive wedge (B) shown in transparent red; result on the right.


  1. Press the Subtractive Wedge button. Note: the Subtractive Wedge is part of an icon menu labelled Create an additive primitive. After launching FreeCAD, the Subtractive Box is the one displayed in the toolbar. To get the Wedge, click on the down arrow besides the visible icon and select Subtractive Wedge in the menu.
  2. Set the Primitive parameters and Attachment.
  3. Click OK.
  4. A Wedge feature appears under the active Body.


The Wedge 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.


Using the default placement, the below inputs are:

  • DataX min/max : Base face X axis span
  • DataY min/max: Wedge height span
  • DataZ min/max : Base face Z axis span
  • DataX2 min/max : Top face X axis span
  • DataZ2 min/max : Top face Z axis span


Wedges can be used to create pyramids by setting DataX2 min/max and DataZ2 min/max each so that min = max.
