Croquis

Introducción

En FreeCAD la palabra "Boceto" se usa normalmente para referirse a un Sketcher SketchObject (Sketcher::SketchObject clase) que es definida por el Ambiente de trabajo Croquizador. Este es un dibujo 2D que utiliza restricciones matemáticas para describir la geometría 2D con precisión.

See Sketcher SketchObject for more information about this type of object.

Utilización

Hay dos maneras comunes de crear un Croquis: usando el Ambiente de trabajo Croquizador directamente, o a través del Ambiente de trabajo DiseñoPieza.

Ambiente de Trabajo Croquizador

1. Cambiar a la Ambiente de Trabajo Croquizador.
2. Presiona Croquizador NuevoBoceto.

Ambiente de Trabajo DiseñoPieza

1. Cambiar a la Ambiente de Trabajo DiseñoPieza.
2. Press Cuerpo DiseñoPieza.
3. Press DiseñoPieza NuevoBoceto.

Cuando termines de editar el boceto, ciérralo para salir del modo de edición. Haz doble clic en él para volver a entrar en el modo de edición.

Notas

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; in the same way, they can be used to define the shape of Arch Walls.
