TechDraw Module/de



FreeCad ist eine 3D-CAD-Software, mit der Gegenstände in erster Linie virtuell erzeugt und in 3D abgebildet werden. Mit Hilfe des FreeCad-Programm-Teils "Technisches Zeichnen" lassen sich die vor der Entwicklung von 3D-CAD-Systemen zur Herstellung dieser Gegenstände ausschließlich benutzten mehrfachen 2D-Darstellungen in Form von Technischen Zeichnungen weiterhin anfertigen. Sie werden vom virtuell modellierten Gegenstand abgeleitet.

Der Betrachter muss sich aber den Gegenstand nicht mehr nur mit Hilfe dieser zweidimensionalen Abbildungen (Ansichten, Schnitte u.ä.) vorstellen, denn eine die Vorstellung erleichternde, ohnehin vorhandene 3D-Abbildung lässt sich beifügen.

Dimensions and hatched areas can be added to Views.

Beachten Sie, dass, wenn Ihr primäres Ziel die Erstellung komplexer 2D-Zeichnungen ist, Sie vielleicht ein spezielles Tool wie LibreCad, QCad, TurboCad usw. in Betracht ziehen möchten.



Pages
These are tools for creating Pages.


 * TechDraw_New_Default.png New Default: Adds a new Page using the default Template.


 * TechDraw_New_Pick.png New Pick: Adds a new Page using a selected Template.

Views
These are tools for creating Views.


 * techdraw-view.png New View: Adds a 2D View of a one or more Drawable Objects.


 * techdraw-projgroup.png New Projection Group: Invokes a dialog for creating Views of one or more Drawable Objects from multiple directions.


 * techdraw-viewsection.png New Section: Adds a cross-section View of one or more Drawable Objects.


 * techdraw-viewdetail.png New Detail: Adds a detail View of a portion of an existing View.


 * techdraw-annotation.png New Annotation: Adds a text block to a Page.


 * techdraw-draft-view.png New Draft: Adds a View of a Draft module object.


 * techdraw-arch-view.png New Arch: Adds a View of a Arch module Section Plane object.


 * techdraw-spreadsheet.svg Spreadsheet: Inserts a view of a selected spreadsheet into a drawing.

Clips
These are tools to create and manage clipped views.


 * techdraw-clip.svg Clip: Inserts a clip group into a Page.


 * techdraw-clipplus.svg ClipPlus: Adds a View to a clip group.


 * techdraw-clipminus.svg ClipMinus: Removes a View from a clip group.

Dimensions
These are tools for working with Dimensions. Linear dimensions can be based on two points, one line or two lines.


 * Dimension_Length.png New Length: Adds a Length Dimension.


 * Dimension_Horizontal.png New Horizontal: Adds a horizontal distance dimension.


 * Dimension_Vertical.png New Vertical: Adds a vertical distance dimension.


 * Dimension_Radius.png New Radius: Adds a Radius dimension to a circle or circular arc.


 * Dimension_Diameter.png New Diameter: Adds a Diameter dimension to a circle or a circular arc.


 * Dimension_Angle.png New Angle: Adds an Angle dimension between two straight edges.


 * Dimension_Link.png New Links: Links 1 or more Dimensions to 3D geometry.

Import/Export
These are tools for exporting Pages to other applications.


 * techdraw-saveSVG.png Save SVG: Saves a Page as an SVG file.

Decoration
These are tools for changing the appearance of Pages and Views.


 * techdraw-hatch.png Hatch Area: Applies a hatch pattern from a file to a Face.


 * techdraw-geomhatch.png Geometric Hatch: Hatches a Face using an Autodesk PAT specification.


 * techdraw-symbol.png New Symbol: Inserts an SVG symbol into a Page.


 * Techdraw-image.png New Image: Inserts a png/jpg image into a Page.


 * techdraw-toggleframe.png Toggle Frames: Turns View frames and labels on or off in a Page.


 * TechDraw_Tree_Page_Sync.png Redraw Page: Redraws a Page without recalculating.

Additional features

 * Hatching: TechDraw supports a number of hatching techniques.
 * Line Groups: default weights can be assigned to various line types.

Einstellungen
Vom Benutzer gewünschte Einstellungen (Liniendicke, Linienart u.v.m.) lassen sich in zwei Fenstern vornehmen. Aufruf: "Einstellungen" unter dem Hauptmenü "Bearbeiten".

Scripting
The TechDraw module features a Python API so you can use its functions in scripts and macros.

Limitations

 * TechDraw drawings and Python API are not interchangeable with the Drawing module. It is possible to convert Drawing Pages to TechDraw Pages using Python (moveViews.py). It is possible to have both TechDraw and Drawing Pages in the same FreeCAD document.
 * There are minor differences in specifying Editable Texts in Templates compared to the Drawing module. See forum discussion  here.
 * TechDraw is available starting with FreeCAD 0.17.

Workarounds

 * None required at the moment.
