Sketcher ToggleConstruction/en

Description
This tool toggles sketch geometry from/to construction mode. It can be used on any type of geometry: line, arc or circle.

Construction geometry is an important tool of the sketcher. When using a sketch for a 3D operation, construction geometry is ignored.

In, construction geometry is shown as blue, and won't turn green when a sketch is fully constrained. Once you, construction geometry is hidden in the 3D view.

Construction lines can be used as rotation axis by the feature.



Usage
There are two ways of using this tool:
 * 1) Without having anything selected in the 3D view:
 * 2) * Invoke construction mode by clicking on the button or by using the  entry in the Sketcher menu.
 * 3) * This will change the color for creating new geometric elements to blue.
 * 4) * Newly created geometric elements will now be created in construction mode.
 * 5) With one or more geometric elements selected in the 3D view
 * 6) * Invoke the tool by clicking on the button or by selecting it from the menu
 * 7) * The selected elements will now be changed to construction mode.
 * 8) * Afterwards newly created elements will again be normal geometry.

Example
Use Construction mode on some sketch elements,



and once you, geometry that was turned into construction have become invisible in the 3D view (but are still present in the Sketcher editing mode).
