Introduction
Dans FreeCAD, le mot "Sketch" est normalement utilisé pour désigner une Objet esquisse (Sketcher::Sketcher::SketchObject
class) définie par l'atelier Sketcher. Il s'agit d'un dessin 2D qui utilise des contraintes mathématiques pour décrire avec précision la géométrie 2D.
Voir Sketcher SketchObject pour plus d'informations sur le type d'objet.
Comment l'utiliser
Il existe deux manières courantes de créer une esquisse: directement dans l'atelier Sketcher, ou à partir de l'atelier PartDesign.
Sketcher Workbench
- Switch to the Sketcher Workbench.
- Press Sketcher NewSketch.
PartDesign Workbench
- Switch to the PartDesign Workbench.
- Press PartDesign Body.
- Press PartDesign NewSketch.
Notes
A Sketch is very commonly used in conjunction with the PartDesign Workbench to create solids by extrusion, using the PartDesign Pad operation.
Nevertheless, a Sketch can always be created by itself for any other purpose; it does not have to be tied to a PartDesign Body. For example, the Arch Window tool of the Arch Workbench uses Sketches to define the shapes of windows and doors.
