Aside from using manipulators described above, size and position of workplane's rectangle in the 3D scene can be customized using the Change Size and Position command. It is available in workplane's contextual menu. Upon calling the command, the view becomes normal to the workplane and red square manipulators appear on rectangle's edges. Set the desired configuration by dragging manipulators.
In addition to standard options for exiting the command with or without confirming changes, there are following options available in the automenu of the Change Size and Position command:
<W> |
Draw On Workplane |
This option activates the mode of drawing on active workplane.
<P> |
Set page size |
This option invokes the dialog, where you can set X and Y global coordinates of bottom left (1st corner) and top right (2nd corner) vertices of the workplane's rectangle.
Alternatively, you can change size and position of workplane's rectangle using the document parameters dialog (Document Parameters > Page > Paper > Origin).
In order to access workplane parameters, use the filter and drop-down list located at the top of the document parameters dialog.
