Introducción

El entorno de Boceto permite dibujar rápidamente objetos 2D simples en el documento actual, y ofrecer diversas herramientas para poderlas modificar después. Algunas de dichas herramientas también funcionan sobre otros objetos de FreeCAD, no sólo en los creados con el entorno de Boceto. También proporciona un completo sistema de ajuste, y varias utilidades para manejar objetos y configuraciones.

The created 2D objects can be used for general drafting in a way similar as is done with Inkscape or Autocad. These 2D shapes can also be used as the base components of 3D objects created with other workbenches, for example, the Workbench Part.svg Part and Workbench Arch.svg Arch Workbenches. Conversion of Draft objects to Workbench Sketcher.svg Sketches is also possible, which means that the shapes can also be used with the Workbench PartDesign.svg PartDesign Workbench for the creation of solid bodies.

FreeCAD is primarily a 3D modelling application, and thus its 2D tools aren't as advanced as in other drawing programs. If your primary goal is the production of complex 2D drawings and DXF files, and you don't need 3D modelling, you may wish to consider a dedicated software program for technical drafting such as LibreCAD, QCad, or others.

Draft Workbench Example

Dibujando objetos

Estas son las herramientas para crear objetos.

  • Draft Line.png Línea de 2 puntos: Dibuja un segmento de línea entre 2 puntos
  • Draft Wire.png Polilínea (Línea de múltiples puntos): Dibuja una polilínea compuesta por múltiples segmentos de línea
  • Draft Circle.png Circunferencia: Dibuja una circunferencia a partir de su centro y radio
  • Draft Arc.png Arco: Dibuja un segmento de arco a partir de su centro, radio ángulo de inicio y ángulo final
  • Draft Ellipse.png Ellipse: Draws an ellipse from two corner points
  • Draft Polygon.png Polígono: Dibuja un polígono regular a partir del centro y radio de la circunferencia que lo circunscribe
  • Draft Rectangle.png Rectángulo: Dibuja un rectángulo a partir de 2 puntos de su diagonal
  • Draft Text.png Texto: Dibuja una anotación de múltiples líneas de texto
  • Draft Dimension.png Cota: Dibuja una cota dimensional
  • Draft BSpline.png BSpline: Dibuja una B-Spline a partir de una serie de puntos
  • Draft Point.png Punto: Inserta un objeto punto
  • Draft ShapeString.png ShapeString: The ShapeString tool inserts a compound shape representing a text string at a given point in the current document
  • Draft Facebinder.png Facebinder: Creates a new object from selected faces on existing objects
  • Draft BezCurve.png Bezier Curve: Draws a Bezier curve from a series of points
  • Draft Label.png Label: Places a label with an arrow pointing to a selected element Disponible en la versión 0.17

Annotation objects

Modificando objetos

Estas son las herramientas para la edición de los objetos existentes. Trabajan sobre los objetos seleccionados, pero si no hay ningún objeto seleccionado, permiten seleccionar uno.

Many operation tools (move, rotate, array, etc.) also work on solid objects (Part, PartDesign, Arch, etc.).

  • Draft Shape2DView.svg Shape 2D View: creates a 2D object which is a flattened 2D view of a 3D object.

Obsolete

This command is considered obsolete because the Drawing Workbench is obsolete. However, the command itself is still available.

These commands have been removed from the interface.

Draft Tray toolbar

The Draft tray toolbar appears when the workbench is started, and allows selecting the working plane, together with some visual properties like the line color, shape color, text size, line width, and automatic group.

Draft Snap toolbar

The Draft Snap toolbar allows selecting the currently snapping mode. Its button keep depressed when a mode is active.

  • Draft ToggleSnap.svg Toggle snap: toggles object snapping globally on or off.
  • Snap Endpoint.svg Endpoint: snaps to the endpoints of line, arc and spline segments.
  • Snap Midpoint.svg Midpoint: snaps to the middle point of line and arc segments.
  • Snap Center.svg Center: snaps to the center point of arcs and circles.
  • Snap Angle.svg Angle: snaps to the special cardinal points of circles and arcs, at 45° and 90°.
  • Snap Intersection.svg Intersection: snaps to the intersection of two line or arc segments. Hover the mouse over the two desired objects to activate their intersection snaps.
  • Snap Perpendicular.svg Perpendicular: on line and arc segments, snaps perpendicularly to the latest point.
  • Snap Extension.svg Extension: snaps on an imaginary line that extends beyond the endpoints of line segments. Hover the mouse over the desired object to activate its extension snap.
  • Snap Parallel.svg Parallel: snaps on an imaginary line parallel to a line segment. Hover the mouse over the desired object to activate its parallel snap.
  • Snap Special.svg Special: snaps on special points defined by the object. introduced in version 0.17
  • Snap Near.svg Near: snaps to the closest point or edge on the nearest object.
  • Snap Ortho.svg Ortho: snaps on imaginary lines that cross the last point, and extend at 0°, 45° and 90°.
  • Snap Grid.svg Grid: snaps to the intersections of the grid lines, if the grid is visible.
  • Snap WorkingPlane.svg Working plane: always places the snapped point on the current working plane, even if you snap to a point outside that working plane.
  • Snap Dimensions.svg Dimensions: shows temporary X and Y dimensions while snapping.
  • Draft ToggleGrid.svg Toggle grid: toggles the visibility of the grid on or off.

Herramientas de utilidad

Utility menu

Herramientas adicionales disponibles desde el menú contextual del botón derecho del ratón, dependiendo de los objetos seleccionados.

Obsolete

These tools were removed from the interface in v0.19 because they no longer had any purpose.

Preferencias

Formatos de archivo

El módulo de Boceto proporciona a FreeCAD importadores y exportadores para los siguientes formatos de archivo:

Install importers

Características adicionales

  • Ajuste: Permite colocar los nuevos puntos en lugares especiales de los objetos existentes
  • Restricciones: Permite situar los puntos nuevos horizontal o verticalmente respecto a puntos previos
  • Trabajando con coordenadas manualmente: Permite introducir coordenadas manualmente, en lugar de indicarlas en la pantalla
  • Working plane: Allows you to define a plane in the 3D space, where next operations will take place

Unit tests

See also: Test Workbench.

To run the unit tests of the workbench execute the following from the operating system terminal.

freecad -t TestDraft

Archivos de guión

El módulo Boceto presenta una completa Draft API para que pueda usar sus funciones en scripts y macros

The workbench includes a module to create samples of all objects in a new document. introduced in version 0.19

Use this to test that all objects are produced correctly.

import drafttests.draft_test_objects as dto
doc = dto.create_test_file()

Inspecting the code of this module is useful to understand how to use the programming interface.

$INSTALLDIR/Mod/Draft/drafttests/draft_test_objects.py

Where $INSTALLDIR is the toplevel directory where the software was installed; for example, in Linux it may be /usr/share/freecad.
