Draft SelectPlane

Description
The Draft module features a working plane system, that allows you to specify a custom plane in the 3D space on which next Draft command will occur. There are several methods to define the working plane:
 * From a selected face
 * From the current view
 * From a preset: top, frontal or lateral
 * None, in which case the working plane is adapted automatically to the current view when you start a command, or to a face if you start drawing on an existing face.



How to use

 * 1) Press the  button.  If your button doesn't look like this, see this note.

Options

 * To set the workplane to an existing face: select a face of an existing object in the 3D view, then press the button
 * Pressing the button will set the working plane as the view plane, perpendicular to the camera axis and passing through the (0,0,0) origin point.
 * Pressing the will unset any current working plane. The next 2D operations will be view-dependent.
 * You can also specify an offset value, which will set your working plane at a certain distance from the plane you select.

Scripting
Working plane objects can easily be created and manipulated in scripts and macros. You can create your own, and use them independently of the current Draft working plane.

Example: You can also access the current Draft working plane: The working plane has a complete scripting API on its own, with convenience functions to position it and convert to/from placements.
