Limitations of the 3D-Premium Import

The following limitations apply to CATIA, Pro/E Creo, Inventor, SolidWorks, SolidEdge, Siemens/UG NX, STEP, IGES, VDA, SAT, JT and Parasolid files during the Premium-Import into the 3D-Tool Viewer and during conversion using the 3D-NativeCAD Converter.

Common

  • Assembly attributes
    Attributes assigned on the assembly level are not read by the viewer or the converter, for example: Colors assigned on the assembly level get lost and Elements hidden on the assembly level will be loaded.
  • Assembly features
    Features (e.g. cuts, bodies, holes) added on the assembly level are not supported and ignored by the viewer or the converter. The support of patterns added on the assembly level is limited in the viewer or the converter.
  • Properties and attributes
    The viewer and the converter have limited support of common properties such as Color and Name. Further properties (e.g. material properties, user defined properties) are not supported by the viewer and the converter.
  • Product Manufacturing Information (PMI)
    The viewer supports the display of most PMI data for models out of CATIA V5/V6, Pro/Engineer, Creo and Siemens/UG NX. Limitation of PMI display can be found in the file format specific limitations. The converter does not support the conversion of PMI data, not even to output formats that support PMI.
  • 2D-data / 2D-sketches
    2D-data and 2D-sketches are not supported by the viewer or the converter.
  • Layers
    Layers are not displayed in the viewer. In the converter the translation of layer information is limited.
  • Free parts, faces, and curves
    The converter supports free parts, faces, and curves only on the top assembly level and not within sub-assemblies.
  • Axes, planes, and local coordinate systems
    The support of axes, planes, and local coordinate systems is limited in the converter.
  • User-defined views
    User-defined views and component views are not supported by the viewer or the converter.
  • Graphical data (visualization data)
    The converter does not support graphical visualization data that is contained in 3D-CAD files in addition to the CAD/BREP-data. The viewer supports the display of this graphical data when the import settings are set to "CAD - graphical data". The viewer will read the highest level of display (LOD) from the part level. Graphical data from the assembly level is not supported by the viewer.
  • Embedded triangulated data
    Triangulated data embedded in 3D-CAD-files is not supported by the converter. The viewer will only read embedded triangulated data via the import setting "CAD - graphical data".
  • Supressed elements
    Suppressed element will not be read by the viewer or the converter, not even by activating the "Load hidden elements" or "Convert hidden elements" option.
  • Hidden elements
    Hidden elements will be read by the viewer or the converter when the "Load hidden elements" or "Convert hidden elements" option is activated. If such hidden elements are converted to file formats that do not support hidden elements (e.g. STEP) the hidden elements will be visible.

CATIA V5 / V6

  • The converter does not support 3DXML files. The viewer will read 3DXML files featuring static tessellation. XML tessellation is not supported by the viewer
  • CGR files can be display in the viewer but are not supported by the converter.
  • All parts and sub-assemblies of an assembly file (*.CATProduct) have to be in the folder of the assembly file or sub-folders, otherwise they will not be read by the viewer or the converter.
  • File names may only contain characters of the ISO-646 character set. Additionally the characters < > * : " ? \ | / cannot be used. During the conversion to CATIA V5 all invalid characters in file and part names will be replaced by an underscore.
  • The viewer does not support the display of PMI data without geometry references, PMI data for hole features in user defined patterns and PMI data for hole features on assembly level.
  • During the conversion to CATIA V5 the attributes line-type and line-thickness will only be translated for free wires and curves, not for edges.
  • Due to hardware requirements, it may not be possible to view or convert CATIA V5 files using an older computer (approx. before 2003). If you plan to use 3D-Tool Premium on such a system, request a free Trial Key to test the import and conversion.

IGES

  • Binary and compressed IGES files are not supported by the viewer or the converter
  • IGES files often do not contain information on face normals (inside/outside). This may lead to flipped surfaces when IGES files are imported into 3D-Tool. That means the inside of surfaces is turned outside which can have negative effects especially on volume calculation and other analysis of the model.

Inventor

  • All parts and sub-assemblies of an assembly file (*.iam) have to be in the same folder, otherwise they will not be read by the viewer or the converter.
  • Attributes, such as color and layer, are not read by the viewer or the converter. This also applies to the hidden attribute. Hidden elements will always be displayed and converted.
  • Some special Inventor features, such as "Lofting" and "Weld Symbols", are not supported by the viewer or the converter.
  • Free form surfaces (T-splines) are not supported by the converter.

JT

  • The viewer and the converter only support version 8 and version 9.
  • "Big Endian" files are not supported by the viewer or the converter.
  • The Name and Layer attributes are not supported by the viewer or the converter. The support of the Color attribute is limited.
  • Free points are not supported by the converter.
  • Free curves within graphical data are not supported by the viewer.

Pro/Engineer, Creo

  • All parts and sub-assemblies of an assembly file (*.asm) have to be in the same folder otherwise they will not be read by the viewer or the converter.
  • Instances in family tables are read by the viewer or the converter only if the corresponding XPR and XAS files are present even though these are only optional in Pro/E. Without the XPR and XAS files always the generic parts are read.
  • The converter translates local coordinate systems only to file formats that support assemblies (CATIA V5, STEP, IGES, ASAT).
  • The curves "using equation" and "local push" are not supported by the viewer or the converter.
  • Cosmetic features are not supported by the viewer or the converter.
  • The viewer supports product manufacturing information (PMI) starting with Pro/Engineer WF3. There is no support of PMI without geometry reference, PMI text attributes (e.g. font and color), or unicode text. There is only limited support of PMI based on 3D-dimensions as well as hole features and patterns.
  • Hidden "merge features" may not be read correctly by the viewer or the converter.

SolidEdge

  • All parts and sub-assemblies of an assembly file (*.asm) have to be in the folder of the assembly file or its sub-folders, otherwise they will not be read by the viewer or the converter.
  • Coordinate systems and work planes are not supported by the converter.
  • Simplified views will not be read by the viewer or the converter.
  • Assemblies with family tables will be loaded with the master representation from the assembly file and not with the actual version of the assembly used in the main assembly.

SolidWorks

  • All parts and sub-assemblies of an assembly file (*.sldasm) have to be in the folder of the assembly file or its sub-folders, otherwise they will not be read by the viewer or the converter.
  • Colors are supported by the viewer and the converter starting with Solidworks 2004.
  • Colors assigned to instances of parts and assemblies are not read by the viewer or the converter.
  • The units of a model are read by the viewer and the converter starting with SolidWorks 2001. With earlier versions the units are always assumed as meters. This also applies to unsupported units such as feet and inch.
  • Hidden bodies and features within parts are not supported by the viewer or the converter.
  • The attributes "Show", "No-show" and "Hidden" will be read by the viewer or the converter starting with SolidWorks 2004.
  • Configurations are supported starting with SolidWorks 98. In order to display and convert a part within an assembly in its correct configuration, the according configuration must be saved in the part file. This is not necessarily the case, especially not, if older parts have been opened and saved with a newer version of SolidWorks. If configurations are missing, open the part in SolidWorks, activate each configuration, and save the part. Faulty or missing part configurations within SolidWorks assemblies may cause the viewer or the converter to read the assembly only partially or even not at all. The graphical data within SolidWorks files does not provide configurations thus when selecting a configuration for import the viewer will always read the CAD/BREP data even if the import settings are set to "CAD - graphical data".
  • Coordinate systems, work planes, free curves, and free points are not supported by the converter.
  • Only CAD-models out of SolidWorks major versions will be supported by the viewer and the converter. Alpha and beta versions cannot be read.
  • SolidWorks 2015 models are only supported by the 64bit versions of the viewer and the converter.
  • Only unicode text from the "Basic Multilingual Plane" (Plane 0, BMP) is supported. Filenames from the "Supplementary Ideographic Plane" (SIP) are not supported by the viewer or the converter.

UG/Siemens NX

  • All parts and sub-assemblies of an assembly file (*.prt) have to be in the folder of the assembly file or sub-folders, otherwise they will not be read by the viewer or the converter
  • 2D-drawings included in a 3D-model will not be identified as a 2D-drawing by the viewer and will be loaded partly as 3D-curve elements together with the 3D-model.
  • For body cuts the viewer and the converter do not distinguish between the cutting tool body and the body to be cut. Both will be loaded or converted as bodies.
  • Product manufacturing information (PMI) from Siemens NX10 models is not yet supported by the viewer or the converter. PMI without geometry reference and PMI text attributes (e.g. font and color) are not supported.

VDA

  • Errors can occur when reading VDA files with the viewer or the converter, especially if the accuracy of the VDA data is insufficient. If such errors occur, as much data as possible is read. 

Limitations of the 3D-Advanced Import

The following limitations apply when opening models using the Advanced interfaces.

  • Open Edges
    The Advanced-Import does not provide Healing for the generation of "watertight" models. Due to the triangulation of the models during import generally there will be some open edges, in rare cases there can be missing surfaces.
  • IGES
    IGES files often do not contain information on face normals (inside/outside). This may lead to flipped surfaces when IGES files are imported into 3D-Tool. That means the inside of surfaces is turned outside which can have a negative effect on volume calculation and other analyses of the model.

Limitations of the 3D-Basic Import

The following limitations apply when opening models using the Basic interfaces.

  • VRML
    The viewer will only load triangulated data (IndexedFaceSets) from VRML files.

Limitations of the 2D-Import

The following limitations apply to DXF, DWG, and HPGL files when loaded into the 3D-Tool viewer.

  • Embedded pictures
    The display of embedded pictures in the viewer is limited.
  • Filled polylines
    Filled polylines (Trace entities) are not supported by the viewer.
  • AEC objects
    AEC (Architecture, Engineering, and Construction) objects are not supported by the viewer.
