6.5. Opening Files via URL

With JetStream Roamer you can open JetStream published .nwd files via the Internet. Having uploaded

your .nwd file to a web server, this file can then be opened directly from within JetStream. Utilizing

JetStream technology, it will not be necessary for the entire file to be downloaded before navigation can

commence - between 10% and 50% will be sufficient for this, depending on the file structure. (The greater

the hierarchical structure of the model, the closer to 50% will be required for navigation to commence.

Similarly, the lesser the hierarchical structure of the model, the closer to 10% will be required).

To open a file via a URL:

• Go to File, Open URL...

6.6. Appending Files

JetStream enables you to build up a complex scene from smaller models by appending, or uniting,

multiple model files together, which can be of any type that JetStream Roamer supports. (See Chapter 7,

Converting Files for more detailed information on these file formats and their options).

Each file has its own units and when appending more files to the scene, each file is automatically scaled

to match the units of the first file loaded into the scene. Each file type has a default unit associated with it

that it uses when loading files of that type. You can change this associated unit in the Units tab of the

Global Options dialog (see Section 17.10, “ Units Options ” for more detailed information). However,

once a file is loaded, you can change its unit scaling using the Edit, File Units and Transform function.

See Section 11.10, “ Setting a File's Units and Transform ” for more information.

The combined set of models may be published as a single JetStream .nwd file using the JetStream

Publisher plugin. These models can then be viewed with NavisWorks Freedom™ free viewer. See

Section 22.1, “ Publishing from Roamer ” for more information.

You can also save the combined set of models as an .nwf file. No geometry is saved in this format, but a

list of appended files, along with their path relative to the .nwf file is saved, along with any overrides,

comments, redlines, viewpoints or other JetStream specific information. See Section 6.8, “ Saving Files ”

for more information on saving files.

To append a file

• Go to File, Append...

• Click Append on the Standard toolbar.

Note

The standard Open dialog use of Shift and Control keys allows multiple files to be selected and

appended to the current set of models.
