John, Phenomenal! Thanks for providing a solution to my problem. May I ask for some additional detail as to why, from SU's viewpoint, the Home scene must have a Home layer as well as a Layer 0 to have all this work properly? Thanks, Jim

@gamelon said: Thanks, gregw. Works like a charm. Is there some documentation describing this or other combinations? The documentation should have been installed when you loaded the 3Dconnection drivers. On my windows computer it's in the start menu under 3Dconnexion > Documentation. For what it's worth here's a few things that work well for me using the spacemouse with Sketchup: Assign one of the buttons to "Rotation On/Off" so then you don't have to hold the middle mouse button down to lock the rotation. Make a template file with the camera set to parallel projection and with scene tabs setup with the standard views so you can easily zoom and pan in any desired 2D orientation by selecting the scene and then using the assigned button to lock the rotation. The spacemouse also works great with adobe acrobat. I use a dual monitor setup and I normally have reference info in pdf format on one screen. I set the left button on the spacemouse to lock and unlock the zoom in the 3Dconnexion Acrobat settings when I select the acrobat screen.

Dave, Thanks for mentioning about the differences between Scale and Move when working with items in drawing. I learned that lesson the hard way, early on. In this case, since these are metal slides, I was only interested in a pictorial representation that was true to overall size. Issues resulting from scaling like any increase in internal channel size were immaterial. As for the explanation of my problem, your analysis was right on. In order for the correctly sized component to replace the existing ones, I first had to open an existing component for Edit and, then, apply the Reload. Voila, all instances changed to 22". Something so simple, but ... Again, thanks for the help and insights.
