Import Export Preference/fr

Introduction
Les préférences pour les outils d'importation et d'exportation se trouvent dans Éditeur de préférences, dans le menu.

Le nombre d'onglets varie en fonction des types de fichiers disponibles pour effectuer la conversion.

Les paramètres d'importation-exportation affectent la manière dont les fichiers sont importés et exportés vers et depuis FreeCAD. Notez que la boîte de dialogue Préférences d'importation-exportation propose des paramètres de type de fichier pour la plupart des ateliers, mais tous ne peuvent pas importer/exporter tous les types de fichiers.

FreeCAD prend en charge de nombreux formats de fichiers. Pour les formats de fichier suivants, il est proposé d’appliquer des paramètres spéciaux:

Remarque: un tableau de description plus court et plus concis peut être trouvé sur la page wiki Import Export.

DAE
Le format Collada DAE (Digital Asset Exchange) est un format de fichier standard pour l'échange de données maillées. L'atelier Arch peut importer des maillages à partir de fichiers et exporter Arch et d'autres objets basés sur Shape vers le format. La fonctionnalité d'importation Collada dans le module Arch dépend de pycollada. S'il n'est pas installé sur votre système, l'import/export de Collada sera désactivé.

Pour le format DAE, vous pouvez spécifier les éléments suivants :

DWG
DWG (from drawing) is a proprietary binary file format used for storing two- and three- dimensional design data and metadata. Since it is a closed source file format it cannot be directly supported by FreeCAD. Therefore the external file converter ODA is required.

For the DWG format you can only specify the path to ODA. Note: All settings for DXF file format also apply to DWG.

DXF
AutoCAD DXF (Drawing eXchange Format) is a proprietary format to exchange CAD data between AutoCAD and other programs.

For the DXF format you can specify the following:

IGES
The Initial Graphics Exchange Specification (IGES) file format is a file format that allows the digital exchange of information among CAD systems. Since the specification for the STEP file format was published, the development of IGES was stopped in 1996. It is nevertheless still supported by many CAD programs.

The tab IGES is only shown in the preferences if you are in the Part or  PartDesign workbenches or if you have been in these workbenches before.

For the IGES format you can specify the following:

IFC
Industry Foundation Classes (IFC) is a wide spread format to interchange data between BIM applications, used in architecture and engineering.

For the IFC format you can specify the following:

INP
INP is the input file format for the FEM software Abaqus. It is used for the solver CalculiX in the FEM Workbench.

The tab Abaqus INP is only shown in the preferences if you are or if you have been in the FEM Workbench before.

For the INP format you can specify the following:

Mesh Formats
Meshes are a special type of 3D object, composed of triangular faces connected by their vertices and edges. They are widely used for additive manufacturing. FreeCAD provides the Mesh Workbench to create and handle meshes. FreeCAD supports the file formats AMF and its predecessors STL, OBJ, OFF, PLY and SMF.

The tab Mesh Formats is only shown in the preferences if you are in the Mesh Workbench or if you have been in this workbench before.

For the Mesh formats you can specify the following:

OCA
The OCA file format is a community project to create a free, simple and open CAD file format. OCA is largely based on the GCAD file format generated by gCAD3D. Both formats can be imported in FreeCAD and the OCA files exported by FreeCAD can be opened in gCAD3D.

For the OCA format you can specify the following:

STEP
The standard for the exchange of product model data (STEP) file format is an ISO standard for the computer-interpretable representation and exchange of product manufacturing information. STEP is therefore commonly used to exchange 3D data between CAD software. STEP files have the suffix or sometimes.

The tab STEP is only shown in the preferences if you are in the Part or  PartDesign workbench or if you have been in these workbenches before. For the STEP format you can specify the following:

SVG
Scalable Vector Graphics (SVG) is a vector image format for two-dimensional graphics. The vectors make SVG are very useful for technical drawing programs like FreeCAD's TechDraw Workbench because a vector image can be scaled to any size without losing its shape or amount of details. SVG can be scaled to any required resolution and converted to bitmap formats like PNG or JPEG for printing.

For the SVG format you can specify the following:

VTK
The Visualization Toolkit (VTK) is an open-source, freely available software system for 3D computer graphics, image processing and visualization. VTK files are used by the FEM workbench for the post processing of simulation results.

The tab VTK is only shown in the preferences if you are or if you have been in the FEM Workbench before.

For the VTK format you can specify the following:
