The Object Viewer vs. 3D Orbit

By Rick Ellis, Cadapult Software Solutions, Inc., August 12, 2003

At first look, the Object Viewer in Land Desktop and the standard 3D Orbit command in AutoCAD look very similar. Each command allows you to rotate, or orbit, around objects in three-dimensional space. This is great for checking your design or examining surfaces to look for holes, spikes or other errors. They also beat the heck out of the old DDVPOINT command. But this is where the similarities end.

The Object Viewer is typically faster than the 3D Orbit command because it allows you to select only the objects that you want to see in the viewer, rather than orbiting around the entire drawing as you do with the 3D Orbit command. More importantly, the Object Viewer does not affect your UCS, it doesn’t even change the current view of your drawing at all until you use the Set View option. This is very important in Land Desktop because while in LDT you always need to be in the World coordinate system.

So if you haven’t been using it, give the Object Viewer a try. You can find it in the Utilities pull-down in Land Desktop, or just select the objects that you want to see in the Object Viewer and right-click to find an option to use the command.
