New Files

This option resets JetStream and closes existing files.

To create a new file

• Go to File, New

or

• Click New on the Standard toolbar.

Refreshing Files

Refreshing Files

When working in JetStream, it is possible that others may be working on the CAD files you are currently reviewing. For example, if you are coordinating various disciplines on a project, then you may have an overall .nwf file referencing numerous design files. During the iterative stages of the project, any member of the design team could potentially be modifying their CAD files. To ensure the data you are reviewing is current, JetStream provides a refresh function to reload any files that have been modified since commencing the review session. This feature does not reload all of the files you have loaded, merely those modified since last opening them.

To refresh your scene with the latest versions of the currently loaded model files

• Go to File, Refresh...

or

• Click Refresh on the Standard toolbar.

Opening Files

Opening Files

With JetStream Roamer you can open a wide variety of native CAD file types without having to have the CAD application on your machine. See for more detailed information on these file formats and their options. To open a model file

• Go to File, Open...

or

• Click Open on the Standard toolbar.

Appending Files

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 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 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 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 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 for more information on saving files.

To append a file

• Go to File, Append...

or

• Click Append on the Standard toolbar.

Merging Files

Merging Files

When merging multiple .nwf files, that each comprise the same reference files, JetStream will only load a single set of the combined models, along with all review markup (such as tags, viewpoints or comments) from each .nwf file. Any duplicate geometry or markup will be removed when merged. See for more information on .nwf files.

To merge a file:

• Open the first file to be merged, (see for information on how to do this).

Then

• Go to File, Merge...

or

• Click Merge on the Standard toolbar.

Finally

• Browse to and select the file, or files, to be merged.

Merging TimeLiner Data

If a TimeLiner license is available, and two or more merged files contain TimeLiner data, limited merging can be done with this data. Three scenarios are handled.

• If the two TimeLiner data sets are identical, then merging of files can occur without issue.

• If the two TimeLiner data sets are completely unrelated, merging of data in this context will not be successful

• If the two TimeLiner data sets contain the same Primary link then the data set with the most recent link (i.e. the newest file date) is chosen over the other. If the Primary links are different, then the data set with the highest number of tasks will be used, and links will be re-attached wherever possible.

For more information on TimeLiner, see the TimeLiner book.

Saving Files

Saving Files

When you have finished reviewing a model or a set of models and are exiting JetStream, you are prompted to save. When saving to a JetStream .nwf file, only a list with pointers to the files currently loaded is saved, along with the scene's environment, the current view, clash results (if available) and viewpoints. If you want to take a snapshot of the scene, including all geometry, then you need to publish an .nwd file. See for information on how to do this.

Saving a file

1. • Go to File, Save

   or

   • Click Save on the Standard toolbar.

2. Enter a name and location for the file, if you wish to change the existing name.

3. Click Save to save the file or Cancel to return to JetStream without saving.

Saving and Renaming Files

Saving and Renaming Files

This is exactly the same as the Save function (see , but it gives you the opportunity to rename the file that you are saving.

Saving a file with a new name

1. Go to File, Save As...

2. Enter a new name and location to store the file.

3. Click Save to save the file or Cancel to return to JetStream without saving.

Publishing Files

Publishing Files

Publishing a NavisWorks .nwd file takes a snapshot of the current scene that cannot then be changed (i.e. files cannot be deleted from a published .nwd file). The file can also be used with the NavisWorks Freedom free viewer. This command is only available if you have the JetStream Publisher plugin.

See for more information.

Printing

Printing

You can print a hard copy of the current viewpoint to any printer or plotter.

Deleting Files

Deleting Files

This command deletes the selected files from the scene. It is only available when more than one file is appended in the scene.

To delete a file

• Go to File, Delete File

Emailing Files

Emailing Files

JetStream is a communication tool and the Send feature makes it easy for you to send your current model along with its viewpoints. The Send command uses your current mail exchange service and will prompt you to set one up if it cannot find one.

Sending a mail will first save the current working file, so you are guaranteed to always send the latest review.

To send a file by email from within JetStream

• Go to File, Send...

or

• Click Send on the standard toolbar.

This accesses your mail package and sends the current file as an email attachment.

Receiving 3D Mail

If an .nwf file is received, JetStream will search for the appended files first using the absolute path that the sender originally saved the file with. This is useful if a team is on a local network and the files can be found using the Universal Naming Convention (UNC). Otherwise, a team not sharing a server can organize a project using the same file hierarchy and drive letter and JetStream can find the files this way.

If JetStream is unable to find the files, then the recipient can save the attached .nwf in a directory where all the appended files are located. The .nwf can then look for these files relative to its own location.

This way, you are able to move a whole sub-directory from your projects directory to a completely new location. Save the .nwf file in this new place and it will be able to search for the files from here.

Importing Files

Importing Files

The import option inputs Intergraph PDS review data, including:

• PDS Tags (.tag)

• PDS Display Sets (.dst)

It is also possible to import data that has been exported from previous JetStream sessions, including:

• Viewpoints XML (.xml)

• Search XML (.xml)

• Search Set XML (.xml)

• Clash Test XML (.xml)

See for more information on exporting data from JetStream.

Exporting Files

Exporting Files

The export option outputs the current viewpoint in one of four ways:

• Piranesi EPix format (.epx)

• Windows Bitmap (.bmp)

• Portable Network Graphics format (.png)

• JPEG format (.jpg)

• Rendered image formats (various)

It is also possible to export an animation, or a TimeLiner sequence to:

• Windows AVI (.avi)

Or, as a sequence of individual frames to:

• JPEG format (.jpg)

• Portable Network Graphics format (.png)

• Windows Bitmap (.bmp)

The export option additionally outputs a variety of review data, including:

• PDS Tags (.tag)

• Viewpoints XML (.xml)

• Current Search XML (.xml)

• Search Sets XML (.xml)

• Clash Test XML (.xml)

• Viewpoint Report HTML (.html)

The export option outputs a number of additional review file types:

• Autodesk DWF (.dwf)

• Google Earth KML (.kml)

Controlling the size of an image

Controlling the size of an image

The size of the exported image/animation can be set in various ways:

Explicit allows you full control of the width and height (the dimensions are in pixels).

>Aspect Ratio allows you to set the height, and the width is automatically calculated from the aspect ratio of your current view.

Current View takes the width and height of your current view.

>Anti-Aliasing smoothes the edges of the exported images. The higher the number, the smoother the image, but the longer they take to export. 4x should be adequate for most situations.

Note

There is a maximum size of 2048 x 2048 pixels, for Roamer OpenGL output.

Exporting PDS Tags

Exporting PDS Tags

1. From the File menu, choose Export, PDS Tags...

2. Enter a new filename and location, if you wish to change from those suggested.

3. Click Save to export the .tag file, or Cancel to return to JetStream.

Exporting Viewpoints

Exporting Viewpoints

Viewpoints can be exported from JetStream to an .xml file. These viewpoints contain all associated data, including camera positions, sections, hidden items and material overrides, redlines, comments, tags and collision detection settings.

Once the viewpoint data is exported to this text-based file format, it can either be imported into other JetStream sessions, or it can be accessed and used in other applications. For example, you may want to set up the same viewpoints in your CAD application.

1. From the File menu, choose Export, Viewpoints XML...

2. Enter a new filename and location, if you wish to change from those suggested.

3. Click Save to export the .xml file, or Cancel to return to JetStream.

Exporting Current Search

Exporting Current Search

The search criteria specified in the Find Items dialog box can be exported to an .xml file. This can then be imported into other JetStream sessions. For example, if you have specified a complicated search criteria, containing various logic statements, that relates to all projects you work on, then this feature allows you to specify it once and use it on all projects.

1. From the File menu, choose Export, Current Search XML...

2. Enter a new filename and location, if you wish to change from those suggested.

3. Click Save to export the .xml file, or Cancel to return to JetStream.

Exporting Search Sets

Exporting Search Sets

Saved search sets can be exported from JetStream as an .xml file. These can then be imported into other JetStream sessions and re-used. For example, if you have a number of generic searches that you perform on all of your projects, this feature allows you to specify the searches once and use them on all projects.

1. From the File menu, choose Export, Search Sets XML...

2. Enter a new filename and location, if you wish to change from those suggested.

3. Click Save to export the .xml file, or Cancel to return to JetStream.

Exporting Viewpoints Report

Exporting Viewpoints Report

An .html file can be exported containing a JPEG of all of the saved viewpoints and associated data, including camera position and comments.

1. From the File menu, choose Export, Viewpoints Report HTML...

2. Enter a new filename and location, if you wish to change from those suggested.

3. Click Save to export the report, or Cancel to return to JetStream.

Exporting to Autodesk DWF

Exporting to Autodesk DWF

Autodesk DWF files can be exported from JetStream if a valid Publisher license is available. The exporter creates a .dwf file containing:

• All geometry

• All materials

• Per-vertex colors

• Properties (where available)

To export a DWF file:

1. From the File menu, choose Export, Autodesk DWF...

2. Enter a new filename and location, if you wish to change from those suggested.

3. Click Save to export the file, or Cancel to return to JetStream.

Exporting to Google Earth KML

Exporting to Google Earth KML

Google Earth KML files can be exported from JetStream. The exporter creates a compressed KML file with the extension .KMZ and supports the export of:

• Triangles

• Lines

• Materials (colour and flat transparency only)

• Viewpoints (adjustments may occur due to Google Earth limitations)

• Model Hierarchy

• Hyperlinks (currently only URLs work correctly in Google Earth)

1. From the File menu, choose Export, Google Earth KML... . This brings up the following dialog.

   

2. Select Export model relative to terrain height to put Google Earth in a mode where all heights are measured from the surface of the ground. When this is off all heights are measured from sea-level.

   Note

   When positioning a model relative to sea level, the height of the Google Earth reference points must also be measured relative to sea level. When positioning a model relative to the ground, the Google Earth reference points must be measured relative to the ground.

   Google Earth always places new placemarks at an altitude of zero, irrespective of whether that is relative or absolute.

3. Collapse on export allows different levels of collapsing parts of the model hierarchy in the exported file.

   • None ensures the whole heirarchy is exported

   • All objects collapses everything into one node

   • Files collapses each file into one node

   • Layers collapses each layer into one node

4. Limit number of Polygons should be enabled to restrict the amount of geometry exported into the output file. Geometry is selected on the basis of taking the most obvious objects in preference to the fine detail. If the exported file is too large for Google Earth to display, try enabling this and reducing the number of polygons. View, Scene Statistics in JetStream shows the number of triangles and/or lines in the current project. By setting a polygon limit you are choosing to export only some of these items.

   Note

   Google Earth's ability to handle large numbers of polygons is far more limited than JetStream. Hence it is worth noting that currently Google Earth will consider 1,000,000 polygons as being a big model.

5. The Origin position values are the first pair of reference points on the Google Earth surface, and must always be defined. The JetStream reference point will always be positioned to exactly overlay the Google Earth reference point.

   Second and Third reference points can be used, and if enabled then the position and orientation of the model can be more accurately defined.

6. Use the Import buttons to read-in saved placemark locations from KML files exported from Google Earth.

   The Origin Import button differs slightly from the other two; if the KML file contains multiple placemarks, this button will offer the user the choice of importing second and third reference points if available. The other two buttons will only import a single reference point.

7. The Pick buttons allow the reference point locations to be selected in the main 3D view.

   These points must be visible in the main 3D view prior to exporting, as once the KML Options dialog is open you will not be able to navigate before picking.

   Note

   You may wish to use View, Split to split the main 3D view enabling you to have separate views of each reference point.

Quitting JetStream
