How to move, zoom, rotate the view:

   Press (and hold) the shift-key and move the mouse.
   No mouse button.

   Press and hold the Shift-key and the Ctrl-key and move the mouse.
   Moving from left to right causes the image to enlarge.
   Or using the mousewheel.

   Press (and hold) the Ctrl-key and move the mouse.
   Horizontal movement of the mouse rotates the part in the image
     plane (the center of rotation is always the screen center).
   Vertical movement of the mouse tilts the part in the image
     plane.



Define the display center:
   Enable checkbox RotCen and select the new center
     - Select a vertex or
     - Select a free point (Ctrl drag, pick then a red point)

   The currently active display- and rotation-center is
     indicated by a white axis-system (in the center of the grafic-scene.



Scal.All - Button:
   Display all objects (sets focus and zoom).


Mdl - Button:
   Setting a fixed enlargement,
   according to the value of MODSIZ (approximate maximum size
     of the model).
   Change MODSIZ by function MODSIZ Standards/Tolerances/Modelsize,
     or by Command MODSIZ {value}


Define representation accuracy for circles, ellipses, curves:
    Standards/Tolerances (in the menu bar above)
    Change the Modelsize, 'Modify'.
      This will automatically derive the tolerances and
      the whole model is immediately recalculated.

    The Modelsize directly affects all tolerances;
     - The poligonalisation-tolerance
     - Identical-point tolerance
     - The Model size in the export of mockup models (eg VRML)
