JT (Jupiter Tessellation) is a 3-D graphics format which is considered as an particularly compact, easy to display, yet very rich data format, that also supports data such as dimensions and tolerances. It is therefore very suitable for CAD-data processing applications.

Export to JT:

Select Drawing > Save/Print > Save as > 3-D formats (STEP, ...) on the Ribbon, or > Save as... > 3-D formats (STEP, ...) to open the export window, where you can set the file type JT (*.jt).

At the top right of the dialogue window, the following area will be displayed:

• Parts to be exported: Here you determine whether the complete drawing (All) or only the active part or part list are to be exported (in the latter case, select the Selection list option).
• Thread body:
• Do not transfer: This is the default setting.
• As separate parts: Activate this option if you want the thread bodies to be exported as individual parts.
• United with parent part: Thread bodies will be exported as elements integrated into the drawing.
• Break up part hierarchy: If you do not want to transfer the existing hierarchy of the parts during their export, activate this option. When the part structure of the drawing is broken up, all solid parts will be merged into one part.
• Split up unconnected parts: This option is activated by default. The hierarchy of the parts in a drawing, without their geometrical relations to each other, will be broken up if you deactivate this option. Several solids which are, according to HiCAD part structure, one part, (e.g. Extruded parts with several closed contours) will then be broken up into individual parts.
• Transfer layers: Deactivating this checkbox excludes layers from export.
• Transfer colours: Deactivating this checkbox excludes colours from export.
• Unite sheets: Activate this option if you want to unite all sub-parts of a sheet with its super-ordinate part, thus forming one part.
• Export free points and Export free edges: Activate or deactivate these checkboxes to allow or suppress the export of free points and/or free edges in the drawing (suppress their export if they may cause any problems).
• Export sketches: Activate this checkbox if you want sketches to be exported as well. When you activate this checkbox, please also activate Export free points and Export free edges; otherwise, the sketch may not be exported completely.
• Export displayed parts only: Only the parts that are visible in the active HiCAD view will be exported.

Below this are, you can select the JT File structure (Monolithic, PerPart, FullShatter, Mimic), and select the following, format-specific options:

Insert BREP: If you activate this option, the exact geometry in the form of the older JT-BREPs ("Boundary Representation") instead of a tessellated triangular geometry will be output.

Multisolids as assemblies: If you activate this option, isolated solids will be subdivided into several parts during export.

The Detail level determines how many accuracy levels of the JT model are to be output. Normally it will be sufficient to leave the value 1 unchanged.

To import a JT file, select > Open > STEP, Iges.. and choose the file type JT (*.jt) in the dialogue.

For the import, too, you can specify whether you want layers and colours to be transferred, and Convert FFS into analytical surfaces if desired (activate option).

If you activate the AutoOptimise option, HiCAD automatically performs the surface function Optimise part after import (3-D Standard > Tools > Surface > Further... > Optimise part).

Please note:

A supplement to the JT interface is the XML-based accompanying format PLMXML, that allows a more detailed output of product structures and process data of complex assemblies.

In the Configuration Editor at Active Configuration (Base configuration) > Interfaces > JT/PLMXML you can specify which export options are to be activated or deactivated by default upon function call

In addition to the options selectable in this dialogue (the default values of which are defined in the Configuration Editor), you have the option to specify a JT configuration file in the in the Configuration Editor, which to be used for the export and overwrites all other settings.

An example configuration file can be found at /sys/cadfix/JTConfig/JT.cfg.

It is important for the use of HiCAD-Spoolers that in the configuration file the setting "autoNameSanitize" has been set to "false", as the Spooler could otherwise not recognize the changed file names.
