Draft Downgrade

Description
The Downgrade tool downgrades the selected objects in different ways.

The Downgrade tool performs things such as breaking faces, and deconstructing wires into their individual edges. It can cut a shape with another shape in similar way to Part Cut.

The counterpart to this tool is the Draft Upgrade operation.



How to use

 * 1) Select one or more objects that you want to downgrade.
 * 2) Press the  button or press  then  keys. If no object is selected, you will be invited to select one.

The selected objects are modified or downgraded, according to the following conditions, in order:
 * 1) If only one object is selected and it contains more than one face, each face becomes a separate object.
 * 2) If there are more than one face in the selection, the subsequent objects are subtracted from the first one.
 * 3) If there is only one face in the selection, it gets converted into a wire.
 * 4) Otherwise all wires found in the selection are exploded into single edges.

Options
There are no options for this tool. Either it works with the selected objects or not.
