Trying to find center of screen. Sometimes my students scroll way out there. Is there a simple command to recenter on screen?
FWIW. Zoom Extends shows the whole model.
Sometimes, when importing models from the 3D Warehouse or certain CAD files, there can be some geometry (or text) very far from the origin where you are drawing.
This could result in a ‘empty’ model (it looks as if it is vanished)
