Note

Archive should be used for uploading models with external references (e.g. external parts, material libraries, textures).

Archive will be created automatically if resulting model contains more than one file.

Parameters

SolidWorks

This format does not have any parameters.

Creo

This format does not have any parameters.

NX

This format does not have any parameters.

IGES

Export Parameters

Name	Type	Default value	Description
units	Length Units	mm	Specifies the length unit.
writemode	String	msbo	Specifies preferred type of topological entities. The following values are supported: boundedsurfaces - use Bounded Surface (type 143) when writing solid or sheet bodies. msbo - use Manifold Solid B-Rep (type 186) when writing solid bodies and Bounded Surface (type 143) when writing sheet bodies.

STEP

Import Parameters

Name	Type	Default value	Description
preferredBodyType	String	auto	Specifies the preferred B-Rep shape representation type, which should be imported. The following values are supported: auto - the most appropriate representation is chosen automatically. all - all representations are imported. This includes the main representation and all connected to it via relationships. advancedBRep - prefer ADVANCED_BREP_SHAPE_REPRESENTATION, which stores solid bodies. manifoldSurface - prefer MANIFOLD_SURFACE_SHAPE_REPRESENTATION, which stores sheet bodies with shells. nonManifoldSurface - prefer NON_MANIFOLD_SURFACE_SHAPE_REPRESENTATION, which stores sheet bodies with faces. edgeBasedWireframe - prefer EDGE_BASED_WIREFRAME_SHAPE_REPRESENTATION, which stores wireframe bodies. In case the preferred representation cannot be found, the first appropriate is imported.

Export Parameters

Name	Type	Default value	Description
split	Split mode	monolithic	Specifies the split mode.
units	Length Units	mm	Specifies the length unit.
savePCurves	Boolean	false	Specifies whether p-curves (edge curves in 2D parametric space of face surfaces) should be written. Writing p-curves can be helpful for certain receiving CAD systems to import data from STEP files. However writing p-curves can increase an output file size considerably.

ACIS

Export Parameters

Name	Type	Default value	Description
version	Number	7	Specifies version of the ACIS file. Supported versions are 4 and 7.

Parasolid

This format does not have any parameters.

JT

Export Parameters

Name	Type	Default value	Description
split	Split mode	monolithic	Specifies the split mode.
saveBRep	Boolean	true	Specifies whether part B-Rep representations should be saved.
savePoly	Boolean	true	Specifies whether polygonal representations should be saved.
units	Length Units	mm	Specifies the length unit.

IFC

Export Parameters

Name	Type	Default value	Description
units	Length Units	mm	Specifies the length unit.

Rhino

Import Parameters

Name	Type	Default value	Description
meshType	String	default	The type of mesh to read. Supported values are default, render, analysis, preview.
readHidden	Boolean	false	Specifies whether the hidden objects should be read.
readPCurves	Boolean	true	Specifies whether original parametric curves should be read from the file and impact on the reconstruction of BRep representation.

Export Parameters

Name	Type	Default value	Description
version	Number	6	Specifies version of the Rhino file. Supported versions are 2 to 6.
saveBRep	Boolean	true	Specifies whether part B-Rep representations should be saved.
savePoly	Boolean	true	Specifies whether polygonal representations should be saved.
units	Length Units	mm	Specifies the length unit.

BRep

There are not special parameters for this format.

3DS

This format does not have any parameters.

3MF

This format does not have any parameters.

Collada

This format does not have any parameters.

DXF

This format does not have any parameters.

FBX

Export Parameters

Name	Type	Default value	Description
version	Number	2012	Specifies version of the FBX file. Supported versions are 2012, 2014, 2016 and 2019.
text	Boolean	false	Specifies whether generated file should be written in text form (true) or binary form (false).
units	Length Units	cm	Specifies the length unit.

glTF

This format does not have any parameters.

OBJ

Import Parameters

Name	Type	Default value	Description
grouping	Boolean	false	Specifies whether forced grouping should be enabled to reduce amount of created parts.
units	Length Units	mm	Specifies the length unit.

Export Parameters

Name	Type	Default value	Description
overrideDuplicateNames	Boolean	true	Specifies whether original names should be supplemented by suffix(es) to provide unique name to every instance of the part. This allows to avoid merging of geometries of parts with same name during reading .obj file.
saveNormals	Boolean	true	Specifies whether vertex normal should be saved or not. When vertex normals are stored in the .obj file then the model can be displayed in smooth shading by third-party viewers. Otherwise the model will be displayed in flat shading only.
generateMtl	Boolean	true	Specifies whether material library should be generated or not. The material library contains materials used in the model. If the material library is not created then no colors or materials will be stored.
replaceSpaces	Boolean	false	Specifies whether space characters in part names should be replaced by '_' character or not. It can improve compatibility with receiving systems.
units	Length Units	mm	Specifies the length unit.

STL

Import Parameters

Name	Type	Default value	Description
units	Length Units	mm	Specifies the length unit.

Export Parameters

Name	Type	Default value	Description
text	Boolean	false	Specifies whether generated file should be written in text form (true) or binary form (false).
multipart	Boolean	true	Specifies whether each body is saved in a separate [solid/endsolid] section in STL file.
units	Length Units	mm	Specifies the length unit.

VRML

Import Parameters

Name	Type	Default value	Description
units	Length Units	m	Specifies the length unit.

Export Parameters

Name	Type	Default value	Description
units	Length Units	m	Specifies the length unit.

X3D

Export Parameters

Name	Type	Default value	Description
units	Length Units	m	Specifies the length unit.
saveNormals	Boolean	false	Specifies whether vertex normal should be saved or not. When vertex normals are stored in the file then the model can be displayed in smooth shading by third-party viewers. Otherwise the model will be displayed in flat shading only.

width	Number	200	Specifies width of image.
height	Number	200	Specifies height of image.
displayMode	String	auto	Specifies display mode used for rendering. Should be one of auto, wireframe, shaded, shadedWithBoundaries. auto mode means to use shadedWithBoundaries for BRep representation and shaded otherwise.
representation	String	auto	Specifies representation used for export. Should be one of auto, brep,poly, finePoly, mediumPoly, coarsePoly. auto mode means to use BRep representation if available and Poly otherwise.
cameraProjection	String	isometric	Specifies camera projection type. Should be one of isometric and perspective.
