Borrador DXF
Descripción
El borrador DXF es un módulo de software utilizado por el Std Abrir, Std Importar y Std Exportar para manejar el formato de archivo DXF.
Dibujo Qcad exportado a DXF, que posteriormente se abre en FreeCAD
Importación
Two importers are available, which one is used can be specified under Edit → Preferences... → Import-Export → DXF. One is built-in, C++-based and fast, the other is legacy, coded in Python, slower, and requires the installation of an add-on, but can handle some entities better and can create more refined FreeCAD objects. Both support all DXF versions starting from R12.
Los objetos 3D dentro de un archivo DXF se almacenan bajo un blob binario ACIS/SAT, que por el momento no puede ser leído por FreeCAD. Sin embargo, entidades más sencillas como los 3DFACEs son soportados.
C++ importer
This importer can import the following DXF objects:
- lines
- polylines (and lwpolylines)
- arcs
- circles
- ellipses
- splines
- points
- texts and mtexts
- dimensions
- leaders
- blocks (only geometry, texts, dimensions and attributes inside blocks are skipped)
- layers
- paper space objects
Legacy importer
This importer can import the following DXF objects:
- lines
- polylines (and lwpolylines)
- arcs
- circles
- ellipses
- splines
- 3D faces
- texts and mtexts
- leaders
- layers
Exportación
Los archivos se exportan en el formato DXF R14, que puede ser manejado por muchas aplicaciones.
C++ exporter
Some of the features and limitations of this exporter are:
- All FreeCAD 2D geometry is exported, except Draft CubicBezCurves, Draft BezCurves and Draft Points.
- Straight edges from faces of 3D objects are exported, but curved edges only if they are on a plane parallel to the XY plane of the global coordinate system. Note that a DXF created from 3D objects will contain duplicate lines.
- Texts and dimensions are not exported.
- Colors are ignored.
- Layers are mapped from object names.
Legacy exporter
Some of the features and limitations of this exporter are:
- All FreeCAD 2D geometry is exported, except Draft Points. But ellipses, B-splines and Bézier curves are not exported properly.
- 3D objects are exported as flattened 2D views.
- Compound objects are exported as blocks.
- Texts and dimensions are exported.
- The colors in the DXF are based on the line color of objects. Black is mapped to "ByBlock", other colors are mapped using AutoCAD Color Index (ACI) colors.
- Layers are mapped from layer and group names. When groups are nested, the deepest group gives the layer name.
Instalación
Por razones de licencia, las librerías de importación/exportación DXF necesarias para la versión antigua del importador no forman parte del código fuente de FreeCAD. Para más información ver: Importación FreeCAD y DXF.
Preferencias
Para más información, consulte: Preferencias de exportación.
Scripting
See also: Autogenerated API documentation and FreeCAD Scripting Basics.
To export objects to DXF use the export
method of the importDXF module.
importDXF.export(objectslist, filename, nospline=False, lwPoly=False)
- For the Windows OS: use a / (forward slash) as the path separator in
filename
.
Ejemplo:
import FreeCAD as App
import Draft
import importDXF
doc = App.newDocument()
polygon1 = Draft.make_polygon(3, radius=500)
polygon2 = Draft.make_polygon(5, radius=1500)
doc.recompute()
objects = [polygon1, polygon2]
importDXF.export(objects, "/home/user/Pictures/myfile.dxf")
