Alternatively, uncheck this option and manually enter the limit.
3. On Load. The Collapse on Convert list box can be set to alter layers shown in the Selection Set
window on loading native CAD model files. Each type collapses the Selection Set tree up to the
specified level. So None does not collapse the tree, Composite Objects collapses the tree up to the
level of composite objects, etc. This enables performance to be prioritized over structure/properties
and has the added benefit of improving streaming by cutting down the logical structure.
It should be noted that whilst JetStream will try to collape items to the fewest number possible, it may
be necessary to prevent collapsing in some cases to preserve model fidelity. For example if an item
has properties or materials unique to itself, then collapsing would endanger this information, and
therefore it will not be collapsed.
The Close NWC/NWD files on load check box, if checked, turns off any streaming on loaded NWC
and NWD files, loading them into memory in their entirety, and then closing them. This allows other
programs to write to these files whilst they are in use.
4. Merge Duplicates. These options improve performance by multiply instancing matching items.
Rather than storing every item in memory, if any items are the same, JetStream can store one
instance of them and 'copy' that instance into other positions. This is of particular benefit on larger
models, where there are significant numbers of these duplicate geometries.
The options available determine when JetStream should perform this merging process:
• On Convert. Merge duplicates when converting a CAD file.
• On Append. Merge duplicates when a new file is appended to the current scene.
• On Load. Merge duplicates when loading a file into JetStream.
• On Save NWF. Merge duplicates when saving the current scene out to .nwf.
5. Temporary File Location. Check the Auto check box for JetStream to automatically select your
user Temp directory. Alternatively, if you prefer to select another location, unselect this option and
enter the path accordingly.
12.7. Presenter Options
This dialog is used to control the appearance of Presenter materials in the main navigation window during
navigation. You may want to adjust these settings to get optimum performance from your graphics card
when navigating around heavily textured scenes. For a list of recommended graphics cards, visit
