Do you 3D? If you do, you most assuredly are familiar with the 3DORBIT command (or at least one would hope!)
For years - AutoCAD has determined the centroid of the display when orbitting based on the center of the entire model. This center doesn't always work effectively when you have objects off in one or more directions.
AutoCAD 2015 introduced an option so YOU could control the centroid and consequently orbit about any part of your model you see fit! Check out my Cadalyst video and take control of the 3DORBIT command for yourself!
