Assembly Level Geometry Support for NX Files

2 min read

The Dynamic and Streaming Viewers support the ability to view Assembly Level Geometry for NX files. The NX Assembly view files directly contain 3D geometry at the root level (assembly level), rather than parts that are normally used to define the assembly.

The native CAD assembly files can contain 3D component geometry. To create Assembly Level Geometry FileRepresentation view files for NX files, the ConversionServerConfig file in the root Aras Innovator folder is updated with the command-line option. The FileRepresentations view file is generated during the conversion process, and the default Query Definition supports viewing this structure in the Dynamic Viewer or Streaming Viewer.

The following figure describes the process.

The default Tree Grid View Definition for Dynamic and Streaming Viewers is modified with a row for Assembly Level Geometry view file. The new row contains a text called body.

The following steps outline the configuration to view the Assembly Level Geometry for NX files:

  1. Install Aras 3D Visualization package. Refer to the Aras 3D Visualization 35 – Installation Guide.
  2. In the root Aras Innovator folder, change the Assembly Command tag in the ConversionServerConfig.xml file to the following:

  • For Dynamic 3D Viewer:

    <AssemblyCommand dynamicEnabled="True” arguments="--sc_compute_bounding_boxes ‘All’ --input_pdf_template_file ‘C:\Aras\14sp10\Templates\Blank_Template_L.pdf’ --output_pdf '%filepath%\%filename%.pdf’ --output_png '%filepath%\%filename%.png’ --output_png_resolution ‘150x150' --output_scs '%filepath%\%filename%.scs’ --output_xml_assemblytree '%filepath%\%filename%.xml’ --output_prc '%filepath%\%filename%.prc’ --background_color ‘1.0, 1.0, 1.0' --output_logfile '%filepath%\%filename%'" isolatedModelArguments="--output_scs '%filepath%\%filename%.scs’ --import_hidden_object ‘True’ --import_pmi false --output_logfile '%filepath%\%filename%_isolate.log’ ” />

  • For Streaming 3D Viewer:

    <AssemblyCommand arguments="--sc_compute_bounding_boxes ‘All’ --input_pdf_template_file ‘C:\Aras\14sp10\Templates\Blank_Template_L.pdf’ --output_pdf '%filepath%\%filename%.pdf’ --output_png '%filepath%\%filename%.png’ --output_png_resolution ‘150x150' --output_xml_assemblytree '%filepath%\%filename%.xml’ --output_prc '%filepath%\%filename%.prc’ --background_color ‘1.0, 1.0, 1.0' --output_logfile '%filepath%\%filename%'" isolatedModelArguments="--sc_create_scz ‘true’ --output_directory '%filepath%' --import_hidden_object ‘True’ --output_sc '%filepath%\%filename%' --import_pmi false --output_logfile '%filepath%\%filename%_isolate.log’ ” streamingEnabled="True” />

The Assembly Level Geometry FileRepresentation view files are created. After the above configuration step, if a user converts NX assemblies which contains a 3D geometry at the assembly level, an SCS or SCZ file is generated which represents the newly added geometry.

In the Default Dynamic View Definition, this file is represented as an assembly with associated child components and an assembly level geometry associated with a text called Body.
