Thumbnail Views
Thumbnails are useful to get an overall view of where you are in the whole scene and to quickly move the camera to a location in a large model. There are two thumbnails available in JetStream so you can have one showing a section and another showing a plan view if you wish. The thumbnails show a fixed view of the model, with a triangular marker representing your current viewpoint. This marker moves as you navigate, showing the direction of your view. The marker may also be dragged by holding the left mouse button over it and dragging to move the camera in the main navigation view.
Note
The marker changes to a small dot when the thumbnail view is in the same plane as the camera view.
To turn on the plan thumbnail:
Go to View, Control Bars and select Plan Thumbnail
or
Click Plan Thumbnail
on the Workspace
toolbar.
The Plan View thumbnail is displayed
To turn on the section thumbnail:
Go to View, Control Bars and select Section Thumbnail
or
Click Section Thumbnail
on the Workspace
toolbar.
By default the Section Thumbnail shows the view from the front of the model and the Plan Thumbnail shows a plan view. The thumbnail view can be manipulated by right clicking on the view. You can select from the following options: Look From Edit Viewpoint Update Viewpoint Lock Aspect Ratio and Refresh
Right click anywhere in the thumbnail to open the context menu.
Use the Look From menu item and choose from Top Bottom Front Back Left or Right to set the thumbnail view to any of these pre-set viewpoints. You can also choose Current Viewpoint to set the thumbnail view to the active navigation viewpoint.
Choose Update Current Viewpoint to set the current active navigation viewpoint to be the same as that of the thumbnail.
Choose Edit Viewpoint if you want to set up the thumbnail's viewpoint by hand using the Edit Viewpoint dialog (see for more information on this).
Choose Lock Aspect Ratio if you want the aspect ratio of the thumbnail to match that of the main navigation view and remain matching even when the thumbnail dialog is resized. This will usually give gray strips either to the top and bottom, or to either side of the thumbnail view. See for more information on aspect ratio.
Choose Refresh to redraw the thumbnail based on the current setting. Thumbnail drawing uses software OpenGL and so can take a couple of seconds for large models.
