Sketcher SketchObject/fr

Introduction
A Sketcher SketchObject, or formally a, is the base element to create 2D objects with the Sketcher Workbench.

The is derived from Part Part2DObject, which means it is a Part Feature object specialized for 2D geometry. Like Part2DObject, the SketchObject can be attached to planes and faces. In addition to this, the SketchObject can handle geometrical constraints of the lines and curves that are drawn within it.



How to use

 * 1) Switch to the Sketcher Workbench.
 * 2) Press.
 * 3) Select a : XY-plane, XZ-plane, or YZ-plane. Optionally also choose, and give an  value.
 * 4) Press.

The SketchObject can be used by itself to draw on a plane; however, it is most commonly used in conjunction with the PartDesign Workbench to create extruded solids.


 * 1) Switch to the PartDesign Workbench.
 * 2) Press.
 * 3) Press.
 * : XY_Plane (Base plane), XZ_Plane (Base plane), or YZ_Plane (Base plane).
 * 1) Press.

Properties
See Property for all property types that scripted objects can have.

A Sketcher SketchObject ( class) is derived from a Part Part2DObject ( class), therefore it shares all the latter's properties.

In addition to the properties described in Part Part2DObject, the basic Sketcher SketchObject has the following properties in the property editor.

Data

 * : See Part Attachment for more information on all attachment mapping modes.


 * : named constraints, if they exist; otherwise it is an empty list.

View

 * : if it will try setting constraints when the geometry is drawn.


 * : normally, it is the name of the workbench to activate when editing the sketch.
 * : if all objects that depend on the sketch are hidden when opening the sketch.
 * : if the camera position is saved before opening the sketch, and is restored after closing it.
 * : if all objects used in links to external geometry are shown when opening the sketch.
 * : if all objects this sketch is attached to are shown when opening the sketch.
