이 페이지에서 다음 사항을 지정할 수 있습니다.

이름	설명
Scaling factor	파일에 있는 모든 치수는 지정된 비율로 확대/축소됩니다.
Mesher	Sets the meshing program that should be used. If using Netgen, make sure that it is available. This can be checked by using the Mesh Workbench and creating a mesh using Netgen. If it is not available another version of FreeCAD, compiled with Netgen, must be installed.
Tessellation	The tessellation value to use with the Builtin and the Mefisto meshing program.
Grading	The grading value to use for meshing using Netgen. This value describes how fast the mesh size decreases. The gradient of the local mesh size `h(x)` is bound by `abs(Δh(x)) ≤ 1/value`.
Segments per edge	The maximum number of segments per edge.
Segments per radius	The number of segments per radius.
Second order	Allow a second order mesh.
Optimize	Allow optimization.
Allow quads	Allow quadrilateral faces.

DWG

DWG(drawing에서 추출)는 2D 및 3D 설계 데이터와 메타데이터를 저장하기 위한 오토데스크사의 독점적인 비공개 소스 바이너리 파일 형식입니다. FreeCAD는 DWG 파일을 처리하기 위해 별도의 변환기가 필요합니다.

참고: DXF 파일 형식에 대한 모든 설정은 DWG에도 동일하게 적용됩니다.

이 페이지에서 다음 사항을 지정할 수 있습니다.

이름	설명
Conversion method	사용할 DWG 변환기를 선택합니. 자동: FreeCAD는 이 목록의 나머지 순서에 따라 변환기를 자동으로 찾으려고 시도합니다.introduced in 0.21: For LibreDWG the OS search path is searched (`os.getenv("PATH")`), for the other converters default installation paths are assumed. LibreDWG: LibreDWG는 오픈 소스 DWG 읽기 및 쓰기 라이브러리입니다. 일부 DWG 엔티티를 지원하지 않으며, 항상 정확한 결과를 제공하지 못할 수 있습니다. ODA Converter: ODA 파일 변환기는 오픈 디자인 얼라이언스(ODA)에서 제공하는 무료 유틸리티입니다. 매우 우수하고 안정적인 결과를 제공합니다. QCAD pro: QCAD pro is the paid version of the open-source QCAD DXF-based 2D CAD platform. Its DWG converter uses the Teigha libraries from the OpenDesign Alliance and therefore gives the same good results as the ODA File Converter.
Path to file converter	FreeCAD에서 변환기를 찾을 수 없는 경우 여기에 경로를 지정해야 합니다. LibreDWG: dwg2dxf or dxf2dwg on Linux and macOS, dwg2dxf.exe or dxf2dwg.exe on Windows. Either filename can be specified for both the conversion from DWG and to DWG. ODA Converter: ODAFileConverter on Linux and macOS, ODAFileConverter.exe on Windows. QCAD pro: dwg2dwg (a bash script) on Linux and macOS, dwg2dwg.bat on Windows. introduced in 0.21: The path must contain the correct filename.

이름	설명
Show this dialog when importing and exporting	이 옵션을 선택하면 DXF 파일을 가져오거나 내보낼 때마 이 환경 설정 대화 상자가 표시됩니다.
Use legacy python importer	체크되어 있으면 파이썬 가져오기 도구가 사용되고, 그렇지 않으면 최신 C++ 가져오기 도구가 사용됩니다. C++ 가져오기 도구는 더 빠르지만 아직 기능이 많지 않습니다. 파이썬 가져오기 도구는 편집 → 환경설정... → 제도 → 일반 → 내부 정밀도 수준값을 사용합니다. 정확한 가져오기 결과를 얻으려면 이 값을 8 이상으로 설정하세요.
Use legacy python exporter	체크되어 있으면 파이썬 내보내기 도구가 사용되고, 그렇지 않으면 최신 C++ 내보내기 도구가 사용됩니다. C++ 내보내기 도구는 더 빠르지만 아직 기능이 많지 않습니다.
Allow FreeCAD to automatically download and update the DXF libraries	By checking this, you will allow FreeCAD to download the Python converter for DXF import and export. This converter cannot be bundled with FreeCAD because it has a different software license.
가져오기	DXF파일에서 무엇을 가져올지 선택합니다. 텍트트 및 치수를 체크하면, 텍스트와mtexts 도 함께 가져옵니다. 점 을 체크하면, 점들도 함께 가져옵니다. If layouts is checked, paper space objects will be imported too. If blocks is checked, anonymous blocks (which have names beginning with a ) will be imported too.
Create	Select what will be created. If simple Part shapes is selected, only standard Part objects will be created. This is the fastest. If Draft objects is selected, parametric Draft objects will be created whenever possible. If Sketches is selected, sketches will be created whenever possible.
Scale factor to apply to imported files	Scale factor to apply to DXF files on import. The factor is the conversion between the units of your DXF file and millimeters. Example: for files in millimeters: 1, in centimeters: 10, in meters: 1000, in inches: 25.4, in feet: 304.8.
Use colors from the DXF file	If checked, colors will be retrieved from the DXF objects whenever possible. Otherwise default colors will be applied.
Join geometry	If checked, FreeCAD will try to join coincident objects into wires. Note that this can take a while!
Group layers into blocks	If checked, objects from the same layers will be joined into Draft Blocks, which display faster, but are less easily editable.
Use standard font size for texts	If checked, imported texts will get the standard Draft Text size, instead of the size they have in the DXF document.
Use layers	If checked, DXF layers will be imported as Draft Layers.
Import hatch boundaries as wires	If checked, hatches will be converted to simple wires.
Render polylines with width	If checked, if polylines have a width defined, they will be rendered as closed wires with the correct width.
Treat ellipses and splines as polylines	The export of ellipses and splines is poorly supported. Use this option to export them as polylines instead. The setting Max Spline Segment is then the maximum length of each of the polyline segments. If it is set to 0 the whole spline is treated as a straight segment.
Export 3D objects as polyface meshes	If checked, all objects containing faces will be exported as 3D polyfaces.
Export TechDraw Views as blocks	If this is checked, TechDraw Views will be exported as blocks. This might fail for post DXF R12 templates.
Project exported objects along current view direction	If checked, the exported objects will be projected to reflect the current view direction. This option only works if the legacy Python exporter is used.

IFC

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

Note for Linux users: To handle this file format FreeCAD requires the IfcOpenShell module.

IFC Import

On this page you can specify the following:

Name	Description
Show this dialog when importing	If checked, this preferences dialog will be shown when importing IFC files.
Show debug messages	Shows verbose debug messages during import and export of IFC files in the Report view.
Create clones when objects have shared geometry	IFC objects can share a same geometry definition between several objects, only their placement is different. When this option is enabled, clones are used to achieve the same result in FreeCAD. One object is the base object, the others are clones.
Number of cores to use (experimental)	Specify the number of CPU cores to use for IFC import. The maximum number should be smaller than the number of actually available cores. Use 0 to disable this feature.
Import arch IFC objects as	What will be created in FreeCAD for arch IFC objects.
Import struct IFC objects as	What will be created in FreeCAD for struct IFC objects.
Root element	Only subtypes of the specified element will be imported. Keep the predefined element IfcProduct to import all building elements.
Separate openings	If checked, openings will be imported as subtractions, otherwise wall shapes will already have their openings subtracted.
Detect extrusions	If checked, the importer will try to detect extrusions. Note that this might slow things down.
Split multilayer walls	Splits walls made of multiple layers.
Prefix names with ID number	If checked, object names will be prefixed with the IFC ID number.
Merge materials with same name and same color	If several materials with the same name are found in the IFC file, they will be treated as one.
Import Ifc properties in spreadsheet	If checked, each object will have their IFC properties stored in a spreadsheet object.
Allow invalid shapes	If unchecked invalid shapes are not imported.
Exclude list	A comma-separated list of IFC entities to be excluded from imports.
Fit view while importing	Fit view during import on the imported objects. This will slow down the import, but one can watch the import.
Import full FreeCAD parametric definitions if available	Creates a full parametric model on import using stored FreeCAD object properties. To get the FreeCAD properties, the model must have been exported using the option Export full FreeCAD parametric model.
Replace 'Project', 'Site', 'Building' and 'Storey' with 'Group'	If checked, groups will be used to replace the mentioned objects.

IFC Export

On this page you can specify the following:

Name	Description
Show this dialog when exporting	If checked, this preferences dialog will be shown when exporting IFC files.
Export type	Select how the model should be exported: as Standard model, Structural Analysis, or Standard + structural.
Force export as Brep	Some IFC viewers don't like objects exported as extrusions. Use this to force all objects to be exported as BREP geometry. But avoid exporting as Brep if possible as this makes objects non-parametric.
Use DAE triangulation options	Use triangulation options set in the DAE options page.
Join coplanar facets when triangulating	Curved shapes that cannot be represented as curves in IFC are decomposed into flat facets. If this is checked, some additional calculation is done to join coplanar facets.
Store IFC unique ID in FreeCAD objects	When exporting objects without a unique ID (UID), the generated UID will be stored inside the FreeCAD object for reuse the next time the object is exported. This leads to smaller differences between file versions.
Use IfcOpenShell serializer if available	IFCOpenShell is a library for IFC files. Its serializer functionality can produce valid IFC geometry from OCC shapes. Note that this is still an experimental feature.
Export 2D objects as IfcAnnotations	If checked, 2D objects will be exported as IfcAnnotation.
Export full FreeCAD parametric model	If checked, all FreeCAD object properties will be stored inside the exported objects, allowing to recreate a full parametric model on reimport using the option Import full FreeCAD parametric definitions if available.
Reuse similar entities	If checked, similar entities will be used only once in the file if possible. This can reduce the file size a lot, but will make it less easily readable.
Disable IfcRectangleProfileDef	Whenever possible, IFC objects that are extruded rectangles will be exported as IfcRectangleProfileDef. For applications that have problems importing these entities, select this option to ensure that all profiles are exported as IfcArbitraryClosedProfileDef instead.
Auto-detect and export as standard cases when applicable	Some IFC types such as IfcWall or IfcBeam have special standard versions like IfcWallStandardCase or IfcBeamStandardCase. If this option is selected, FreeCAD will automatically export such objects as standard cases when the necessary conditions are met.
Add default site if one is not found in the document	When exporting an IFC file, if no site is found in the FreeCAD document, a default one is added. A site is not mandatory according to the IFC standard, but it is common practice to have at least one in the file.
Add default building storey if one is not found in the document	When exporting an IFC file, if no building storey is found in the FreeCAD document, a default one is added. A building storey is not mandatory according to the IFC standard, but it is common practice to have at least one in the file.
IFC file units	Select which units will be used when exporting IFC files.
Add default building if one is not found in the document	When exporting an IFC file, if no building is found in the FreeCAD document, a default one is added. Warning: The IFC standard asks for at least one building in each file. By turning this option off, you will produce a non-standard IFC file. However, at FreeCAD we believe having a building should not be mandatory, and this option is there to have a chance to demonstrate our point of view.
Export nested groups as assemblies	In FreeCAD, it is possible to nest groups inside buildings or storeys. If this option is disabled, FreeCAD groups will be saved as IfcGroups and aggregated to the building structure. Aggregating non-building elements such as IfcGroups is however not recommended by the IFC standards. It is therefore also possible to export these groups as IfcElementAssemblies, which produces an IFC-compliant file. However, at FreeCAD, we believe nesting groups inside structures should be possible, and this option is there to have a chance to demonstrate our point of view.

IGES

Initial Graphics Exchange Specification (IGES) 파일 형식은 CAD 시스템 간의 디지털 정보 교환을 가능하게 하는 파일 형식입니다. STEP 파일 형식이 발표된 후 IGES 개발은 1996년에 중단되었지만, 여전히 많은 CAD 프로그램에서 지원되고 있습니다. IGES 파일은 .iges 또는 .igs 확장자를 가집니다.

This means volumes for a volume mesh and faces for a shell mesh. If FEM is selected, only FEM elements will be exported. This means only edges not belonging to faces and faces not belonging to volumes.
Export group data	If checked, mesh groups are exported too. Every constraint and, if there are different materials, material consists of two mesh groups, faces and nodes where the constraint or material is applied.

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 several mesh file formats.

This page is only shown if the Mesh Workbench has been loaded in the current FreeCAD session.

This page is only shown if the Part Workbench, PartDesign Workbench, or OpenSCAD Workbench has been loaded in the current FreeCAD session.

On this page you can specify the following:

Name	Description
Write out curves in parametric space of surface	If checked, parametric curves (curves in parametric space of surfaces) will be written into the STEP file. Unchecking the option can be helpful to minimize the size of the resulting STEP file.
Export invisible objects	Uncheck this to skip invisible object when exporting, which is useful for CAD applications that do not support invisibility STEP styling.
Export single object placement	Check this option to keep the placement information when exporting a single object. Please note that when re-importing the STEP file, the placement will be encoded into the shape geometry, instead of keeping it inside the Placement property.
Use legacy export function	Use the legacy export function.
Units for export of STEP	Select which units will be used when exporting STEP files.
Scheme	Select the STEP application protocol (AP) to be used for the export. AP 203 is the protocol for configuration controlled 3D designs of mechanical parts and assemblies. AP 214 is the protocol for core data for automotive mechanical design processes.
Enable STEP Compound merge	If checked, a compound merge will be done during file reading. This is slower but results in higher details.
Use LinkGroup	Select this to use App::LinkGroup group containers instead of App::Part group containers.
Import invisible objects	Select this to import invisible objects.
Reduce number of objects	Reduce the number of objects using Link arrays.
Expand compound shape	Expand compound shapes with multiple solids.
Show progress bar when importing	Show a progress bar when importing.
Ignore instance names	Do not use instance names. Useful for some legacy STEP files with non-meaningful auto-generated instance names.
CodePage	The encoding of STEP files can be specified here.

SVG

확장 가능한 벡터 그래픽 (Scalable Vector Graphics 축약하여 SVG)은 2차원 그래픽을 위한 벡터 이미지 형식입니다. 벡터 이미지는 모양이나 세부 사항을 잃지 않고 어떤 크기로든 확대/축소할 수 있습니다. SVG 이미지는 인쇄를 위해 PNG 또는 JPEG와 같은 비트맵 형식으로 변환할 수 있습니다.

On this page you can specify the following:

Name	Description
Import style	Select how SVG object colors and line widths will be imported. If None (fastest) is selected no color or line width settings will be imported. If Use default color and linewidth is selected FreeCAD will use its default color and line width. If Original color and linewidth is selected FreeCAD will use the color and linewidth from the SVG objects.
Disable units scaling	If checked, no unit conversion will occur. One unit in the SVG file will translate as one millimeter.
Export style	Select how Sketches are exported to SVG. If Translated (for print & display) is selected, SVG objects are encapsulated in a group that is scaled and moved to the correct place in the SVG document to fit into a printable area. If Raw (for CAM) is selected, SVG objects are placed as they are - at the same coordinates as in the FreeCAD model (1:1 export).
Translate white line color to black	If checked, all white lines will appear in black in the SVG for better readability against white backgrounds.
Max segment length for discretized arcs	Versions of Open CASCADE older than version 6.8 don't support arc projection. In this case arcs will be discretized into small line segments. This value is the maximum segment length.

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.

This page is only shown if the FEM Workbench has been loaded in the current FreeCAD session.

On this page you can specify the following:

Name	Description
Which object to import into	Select which objects should be imported and how. If VTK result object is selected, a FreeCAD FEM VTK result object will be imported (equals to the object which was exported). If FEM mesh object is selected, the results in the VTK file will be omitted, only the mesh data will be imported and a FreeCAD FEM mesh object will be created. If FreeCAD result object is selected, the imported data will be converted into a FreeCAD FEM Result object. Note: this setting needs the exact result component names and thus it only works properly with VTK files exported from FreeCAD.
