Import Export Preferences/it

Le preferenze per gli strumenti di importazione ed esportazione si trovano nel Editor delle preferenze, nel menu.

Il numero di schede varia in base ai tipi di file disponibili per la conversione.
 * Forniti da Draft: DXF, DWG, SVG, OCA.
 * Forniti da Arch: IFC, DAE.

Preferenze DXF
La scheda DXF configura come devono essere importati i file DXF. Vedere anche Importare i file DXF in FreeCAD.

AutoCAD DXF (Drawing eXchange Format - Formato di scambio di disegni) è un formato proprietario per lo scambio di dati CAD tra AutoCAD e altri programmi.



Per il formato DXF è possibile specificare quanto segue:

Preferenze DWG
La conversione in DWG richiede il programma esterno.

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.

Converting to DWG requires the external program.

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

Può essere scaricato da teighafileconverter.



For the DWG format you can specify the following:

Preferenze SVG
La scheda SVG configura come vengono importati i file SVG.

The SVG tab configures how SVG files are imported.

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 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:

Preferenze OCA
La scheda OCA configura come vengono importati i file OCA.

The OCA tab configures how OCA files are imported.

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:

Preferenze IFC
La scheda IFC configura come vengono importati i file IFC.

The IFC tab configures how IFC files are imported.

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:

Preferenze DAE
La scheda DAE configura come vengono importati i file DAE.

The DAE tab configures how DAE files are imported.

The Collada DAE (Digital Asset Exchange) format is a standard file format for exchange of Mesh data. The Arch workbench can import meshes from files, and export Arch and other Shape-based objects to the  format. The Collada import functionality in the Arch module depends on pycollada. If it is not installed on your system, Collada import/export will be disabled.



For the DAE format you can specify the following:

Preferenze 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 workbench or if you have been in these workbenches before.



For the IGES format you can specify the following:

Preferenze 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:

Preferenze di Mesh
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. The FreeCAD provides the Mesh workbench to create and handle meshes.

FreeCAD supports the file formats AMF and its predecessor 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:

Preference Abaqus 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:

Preference 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:
