Beschreibung

Siehe auch: FreeCAD und DXF Import und FreeCAD und DWG Import.

Diese Funktion öffnet eine DXF-Datei (Version 12 bis 2007) in ein neues Dokument.

Qcad-Zeichnung nach DXF exportiert, die anschließend in FreeCAD geöffnet wird

Einleitung

Die folgenden DXF-Objekttypen werden derzeit unterstützt:

  • Linien
  • Polylinien und Lwpolylinien
  • Kreise
  • Kreisbögen
  • Ebenen (Ebenen mit Objekten werden in FreeCAD Groups konvertiert)
  • Texte und Mtexte
  • Maße
  • Blöcke (nur Geometrie. Texte, Maße und Attribute in Blöcken werden übersprungen)
  • Punkte introduced in version 0.13
  • Vorlaufe introduced in version 0.13

Andere DXF-Objekte werden derzeit nicht importiert, da kein entsprechendes FreeCAD-Objekt vorhanden ist. Sobald neue Funktionen implementiert werden, können weitere Objekttypen importiert werden.

Installieren

Note: for licensing reasons, the DXF import/export libraries are not part of the FreeCAD source code anymore. For that reason, they must be installed by you, the user, after you install FreeCAD. There is a way to allow FreeCAD to do that automatically, or you can do it manually.

Automatically

Starting from version 0.15, you only need to mark the Edit → Preferences → Import/Export → DXF/DWG → "Allow FreeCAD to automatically download the DXF libraries" option to have FreeCAD take automatically care of downloading and installing these libraries. For older versions, you will need to do it manually.

Manually

Libraries must be downloaded from https://github.com/yorikvanhavre/Draft-dxf-importer There is a very complete step-by-step tutorial that will explain you the necessary steps.

Importing

This works the same way as opening, but it will add the contents of the DXF file in the active document instead of creating a new document.

Tutorial: Dxf Importer Install

Exporting

The exported DXF is compatible with Autocad version 12 and up, so it should open in about any application that supports dxf format. Currently the following FreeCAD objects get exported:

  • lines and wires (polylines)
  • arcs and circles
  • texts
  • colors are mapped from objects RGB colors to autocad color index (ACI). Black will always be "by layer"
  • layers are mapped from group names. When groups are nested, the deepest group gives the layer name.
  • dimensions, which are exported with "Standard" dimstyle

Preferences

The following parameters can be specified in the Preferences Editor, in the menu Edit → Preferences → Import-Export.

  • Import style: This lets you choose the way objects from the dxf file will be drawn in FreeCAD. You can choose between:
    • None: this is the faster way, there is no conversion, all objects will be black with 2px width (FreeCAD default)
    • Use default color and linewidth: All imported dxf objects will take current linewidth/color from the draft command bar
    • Original color and linewidth: Objects will keep the color and linewidth (if specified) they have in the dxf file
    • Colors mapped to linewidth: If this option is selected, the mapping file option below is used.
  • Color mapping file: This allows you to specify a mapping file to be used for translating dxf colors to color and linewidth, the same way as a plot style works in Autocad. The mapping file must be a tab-separated text file. There is a nice free utility called Plot style viewer that can convert Autocad CTB or STB (plot styles) files to tab-separated mapping files ready to use in FreeCAD. Alternatively, we have a couple of home-made mapping files available here.
  • Import texts: This allows you to specify whether you want to import dxf texts and dimensions. Many texts might make your work in FreeCAD very difficult, so you might want to use this option some time.
  • Import layout objects: Turn this on if you want to import paper space object. They will be merged in the same document as model space objects.

Scripting

Siehe auch: Draft API und FreeCAD Scripting Basics.

Du kannst durch die folgende Funktion Elemente nach DXF exportieren:

importDXF.export(objectslist, filename, nospline=False, lwPoly=False)

Beispiel:

import Draft, importDXF

Polygon1 = Draft.makePolygon(3, radius=500)
Polygon2 = Draft.makePolygon(5, radius=1500)

objects = [Polygon1, Polygon2]

importDXF.export(objects, "/home/user/Pictures/myfile.dxf")
