Introduction

Rit modulen är ett pågående arbete och är en ganska experimentell modul som har gjorts för att lägga till grundläggande 2d ritfunktionalitet till FreeCAD. Den är helt och hållet skriven i python, och är även tänkt att fungera som en presentation om hur mycket du kan utöka FreeCAD endast med hjälp av python, utan att ens röra källkoden.

Draft objects can be used for general drafting, similar to what can be done with Inkscape or AutoCAD. But they can also form the base for the creation of 3D objects in other workbenches. A Draft Wire may define the path of an Arch Wall, a Draft Polygon can be extruded with Part Extrude, etc. Many of the Draft modifier tools can be applied to 2D and 3D objects created with other workbenches as well. You can, for example, move a Sketch or create a Draft OrthoArray from a Part object.

The Draft Workbench also provides tools to define a working plane, a grid, and a snapping system to precisely control the position of geometry.

If your primary goal is the production of complex 2D drawings and DXF files, and you don't need 3D modelling, FreeCAD may not be the right choice for you. You may wish to consider a dedicated software program for technical drafting instead, such as LibreCAD or QCad.

Drafting

  • Line: creates a straight line.

  • Polyline: creates a polyline, a sequence of several connected line segments.

  • Fillet: creates a fillet, a rounded corner, or a chamfer, a straight edge, between two Draft Lines.

  • Arc tools:

  • Arc: creates a circular arc from a center, a radius, a start angle and an aperture angle.

  • Arc by 3 points: creates a circular arc from three points that define its circumference.

  • Circle: creates a circle from a center and a radius.

  • Ellipse: creates an ellipse from two points defining a rectangle in which the ellipse will fit.

  • Rectangle: creates a rectangle from two points.

  • Polygon: creates a regular polygon from a center and a radius.

  • B-spline: creates a B-spline curve from several points.

  • Bézier tools:

  • Cubic Bézier curve: creates a Bézier curve of the third degree.

  • Bézier curve: creates a Bézier curve from several points.

  • Point: creates a simple point.

  • Facebinder: creates a surface object from selected faces.

  • ShapeString: creates a compound shape that represents a text string.

  • Hatch: creates hatches on the planar faces of a selected object. (v0.20)

Annotation

  • Text: creates a multi-line text at a given point.

  • Dimension: creates a linear dimension, a radial dimension or an angular dimension.

  • Label: creates a multi-line text with a 2-segment leader line and an arrow.

  • Annotation styles...: allows you to define styles that affect the visual properties of annotation-like objects.

Modification

  • Move: moves or copies selected objects from one point to another.

  • Rotate: rotates or copies selected objects around a center point by a given angle.

  • Scale: scales or copies selected objects around a base point.

  • Mirror: creates mirrored copies from selected objects.

  • Offset: offsets each segment of a selected object over a given distance, or creates an offset copy of the selected object.

  • Trimex: trims or extends a selected object.

  • Stretch: stretches objects by moving selected points.

  • Clone: creates linked copies, clones, of selected objects.

  • Array tools:

  • Array: creates an orthogonal array from a selected object. It can optionally create a Link array.

  • Polar array: creates an array from a selected object by placing copies along a circumference. It can optionally create a Link array.

  • Circular array: creates an array from a selected object by placing copies along concentric circumferences. It can optionally create a Link array.

  • Path array: creates an array from a selected object by placing copies along a path.

  • Path Link array: idem, but create a Link array instead of a regular array.

  • Point Array: creates an array from a selected object by placing copies at the points from a point compound.

  • Point Link array: idem, but create a Link array instead of a regular array.

  • Edit: puts selected objects in Draft Edit mode. In this mode the properties of objects can be edited graphically.

  • Subelement highlight: temporarily highlights selected objects, or the base objects of selected objects.

  • Join: joins Draft Lines and Draft Wires into a single wire.

  • Split: splits a Draft Line or Draft Wire at a specified point or edge.

  • Upgrade: upgrades selected objects.

  • Downgrade: downgrades selected objects.

  • Wire to B-spline: converts Draft Wires to Draft BSplines and vice versa.

  • Draft to Sketch: converts Draft objects to Sketcher Sketches and vice versa.

  • Set slope: slopes selected Draft Lines or Draft Wires by increasing, or decreasing, the Z coordinate of all points after the first one.

  • Flip dimension: rotates the dimension text of selected Draft Dimensions 180° around the dimension line.

  • Shape 2D view: creates 2D projections from selected objects.

Draft Tray

The Draft Tray allows selecting the working plane, defining style settings, toggling construction mode, and specifying the active layer or group.

  • Select Plane: selects the current Draft working plane. Also available in the menu: Draft → Utilities → Select Plane.

  • Set style: sets the default style for new objects. Also available in the menu: Draft → Utilities → Set style.

  • Toggle construction mode: switches Draft construction mode on or off. Also available in the menu: Draft → Utilities → Toggle construction mode.

  • AutoGroup: changes the active Draft Layer or, optionally, the active Std Group or group-like Arch object.

Draft annotation scale widget

With the Draft annotation scale widget the Draft annotation scale can be specified.

Draft snap widget

The Draft snap widget can be used as an alternative for the Draft snap toolbar.

Draft snap toolbar

The Draft snap toolbar allows selecting the active snap options. The buttons belonging to active options stay depressed. For general information about snapping see: Draft Snap.

Draft utility tools toolbar

Additional tools

The Draft → Utilities menu contains several tools. Most of them can also be accessed from toolbars or the Draft Tray and have already been mentioned above. For the following tools this is not the case:

Gemensamt beteende

  • Snäpp: tillåter dig att placera nya punkter på speciella platser på existerande objekt

  • Begränsning: Tillåter att nya punkter placeras horisontellt eller vertikalt i relation till tidigare punkter

  • Konstruktionsläge: Tillåter dig att skilja viss geometri åt från resten, för att lätt kunna stänga på/av

  • Arbetsplan: Alla skisskommandon kan användas på valfritt plani i 3D rymden. Det gällande arbetsplanet kan konfigureras på ett lätt sätt

Tree view context menu

The following additional options are available in the Tree view context menu:

Default options

If there is an active document the context menu contains one additional sub-menu:

  • Utilities: a subset of the tools available in the main Draft Utilities menu.

Wire options

For a Draft Line and a Draft Wire this additional option is available:

  • Flatten: flattens the wire on the current Draft working plane. This option does not work properly in {{VersionMinus|0.19}}.

Layer container options

For a Draft LayerContainer these additional options are available:

Layer options

For a Draft Layer these additional options are available:

Working plane proxy options

For a Draft WorkingPlaneProxy these additional options are available:

  • Write camera position: updates the View Data property of the working plane proxy with the current 3D view camera settings.

  • Write objects state: updates the Visibility Map property of the working plane proxy with the current visibility state of objects in the document.

3D view context menu

The following additional options are available in the 3D view context menu:

Default options

If there is an active document the context menu contains one additional sub-menu:

  • Utilities: a subset of the tools available in the main Draft Utilities menu.

Obsolete tools

These commands are obsolete but still available:

  • Array: creates an orthogonal array from a selected object. The created array can be turned into a polar array or a circular array by changing its Array Type property. {{Obsolete|0.19}}

  • Drawing: inserts views of selected objects into a drawing page. {{Obsolete|0.17}}

Preferences

Import & export

Detta är funktioner för att öppna, importera eller exportera andra filformat. Öppna kommet att öppna ett nytt dokument med filens innehåll, medan importera kommer att lägga till filinnehållet till det nuvarande dokumentet. Exportera kommer att spara de valda objekten till en fil. Om inget är valt, så kommer alla objekt att exporteras. Var uppmärksam på att eftersom tanken med Ritmodulen är att arbeta med 2d objekt, så fokuserar dessa importerare endast på 2d objekt, och, fastän DXF och OCA formaten stödjer objektdefinitioner i 3D rymden (objekt är inte nödvändigtvis platta), så kommer de inte att importera volymetriska objekt som nät, 3D ytor, etc, utan snarare linjer, cirklar, text eller flata former. För närvarande så stöds följande filformat:

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

API

Se Skiss API sidan för en komplett beskrivning av Skissfunktionerna som du kan använda i skript och makron

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

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 can help to understand the programming interface.
