Workbench Draft.svg

Introdução

A bancada Draft permite desenhar objetos 2D simples e oferece várias ferramentas para modificá-los posteriormente. Ele também fornece ferramentas para definir um plano de trabalho, uma grade e um sistema de encaixe para controlar com precisão a posição de sua geometria.

Os objetos 2D criados podem ser usados para desenho geral de maneira similar ao Inkscape ou Autocad. Essas formas 2D também podem ser usadas como componentes básicos de objetos 3D criados com outras bancadas de trabalho, por exemplo, Part e Bancada Arch. A conversão de objetos do Draft para Sketches também é possível, o que significa que as formas também podem ser usadas com a Bancada PartDesign para a criação de corpos sólidos.

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, TurboCad, and others.

Draft Workbench Example

Drawing objects

These are tools for creating objects.

  • Draft Line.svg Line: draws a line segment between two points.
  • Draft Wire.svg Wire: draws a line made of multiple line segments (polyline).
  • Draft Fillet.svg Fillet: draws a fillet (rounded corner) or a chamfer (straight line) between two simple Lines. introduced in version 0.19
  • Draft Circle.svg Circle: draws a circle from center and radius.
  • Draft Arc.svg Arc: draws an arc segment from center, radius, start angle and end angle.
  • Draft Arc 3Points.svg Arc 3Points: draws a circular arc segment from three points that are located in the circumference. introduced in version 0.19
  • Draft Ellipse.svg Ellipse: draws an ellipse from two corner points.
  • Draft Polygon.svg Polygon: draws a regular polygon from center, radius, and number of sides.
  • Draft Rectangle.svg Rectangle: draws a rectangle from two corner points.
  • Draft Text.svg Text: draws a multi-line text annotation.
  • Draft Dimension.svg Dimension: draws a dimension annotation.
  • Draft BSpline.svg BSpline: draws a B-Spline from a series of points.
  • Draft Point.svg Point: inserts a point object.
  • Draft ShapeString.svg ShapeString: inserts a compound shape representing a text string at a given point.
  • Draft Facebinder.svg Facebinder: creates a new object from selected faces on existing objects.
  • Draft BezCurve.svg Bezier Curve: draws a Bezier curve from a series of points.
  • Draft CubicBezCurve.svg Cubic Bezier Curve: draws a Bezier curve of third degree by dragging two points. introduced in version 0.19
  • Draft Label.svg Label: places a label with an arrow pointing to a selected element. introduced in version 0.17

Modifying objects

These are tools for modifying existing objects. They work on selected objects, but if no object is selected, you will be invited to select one.

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

Utility tools

Additional tools available from the menu Draft → Utilities, or via the right-click context menu, depending on the selected object.

Preferences

  • Preferences-draft.svg Preferences: general preferences for the working plane and the drawing tools.
  • Preferences-import-export.svg Import-Export Preferences: preferences available for importing from and exporting to different file formats.

File formats

The Draft module provides FreeCAD with importers and exporters for the following file formats:

Additional features

  • Coordinates: enter coordinates instead of clicking on the 3D view to define a new point.
  • Constraining: limit the pointer to horizontal or vertical movements relative to a previous point.
  • Snapping: place new points on special places on existing objects or on the grid.

Scripting

The Draft tools can be used in macros and from the Python console by using the Draft API.
