Navisworks Freedom 2019 Orthographic Camera jumps all over

Hello,

 

I'm using Navisworks Freedom 2019 to view a model supplied in .nwd format.

 

I'm trying to create some orthographic views to supply our construction team with some general overview shots.  However, when you click on the viewport the camera moves miles away.  This doesn't happen in perspective mode.  It doesn't matter where you click, whether on a model element or background.  It doesn't matter what tool is selected either.

 

Example:

Using the 'focus on item' and navigation cube manage to get the element in view.

Camera position:  X: 675m   Y: 117m   Z: 406m

Click the pan tool somewhere, even click the menu bar...

Camera position:  X: 1270495m   Y: -1269680m   Z: 1270207m

 

It's now very difficult to get the model back in view.  'Focus on item' doesn't really work anymore, just kicks the camera around the environment.

 

This worked fine last time in a different file.  I've just tried another file (different project) and it seems to work okay.  So I guess there's something wrong with the file.  Does anyone know what that could be?

Check the physical extents of the model.  For example, an AutoCAD DWG file may have content modeled in real-world coordinates but have some rogue elements hanging out at the origin (0, 0, 0).  When that happens it's best to deal with it in the source file, but in a pinch hiding it in Navisworks will do the same thing.

Hello, thanks for the idea.  I tried to hide everything outside the model but it didn't change much.

 

The workaround I found was simply using perspective mode but reducing the camera FOV to something like 10-20 degrees that removes the bulk of the distortion.
