DEFINE ROTATION CENTER

 

If this option is toggled on, the user can define the rotation center prior to rotating the model. When the user clicks the  button, eta/DYNAFORM prints the following message in the message prompt window:

PICK A LOCATION AS THE ROTATION CENTER

The user can click anywhere in display window as the rotation center. Then, move the mouse cursor to rotate the model around the center.

 

If the user uses the shortcut key (CTRL+ left mouse button) to rotate the model, the immediate location upon which the mouse cursor is placed is automatically defined as the rotate center. The model is rotated around the center.
