On the left: active body (A) shown in grey and subtractive cone (B) shown in transparent red; result on the right.
Usage
Press the Subtractive Cone button. Note: the Subtractive Cone is part of an icon menu labelled Create a subtractive primitive. After launching FreeCAD, the Subtractive Box is the one displayed in the toolbar. To get to the Cone button, click on the down arrow besides the visible icon and select Subtractive Cone in the menu.
Set the Primitive parameters (for a complete cone, set one of the radii to zero) and the Attachment.
Click OK.
A Cone feature appears under the active Body.
Options
The Cone 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.
