Inferencing
Inferencing displays relations by means of dotted inferencing lines,
pointer display, and highlighted cues such as endpoints and midpoints.
Inferencing lines
|
Inferencing lines appear as you sketch, displaying relations between
the pointer and existing sketch entities (or model geometry). |
|
Pointer display
|
The pointer display indicates when the pointer is over a geometric relation
(an intersection, for example), what tool is active (line or circle),
and dimensions (angle and radius of an arc). If the pointer displays a
relation (such as  for a horizontal relation) and you click
to accept the sketch entity while the relation is displayed, the relation
is added automatically to the entity.
NOTE: You can turn off automatic relations. Click
Tools, Sketch
Settings, Automatic
Relations. |

Highlighted cues
|
Geometric relations such as endpoints, midpoints, and vertices highlight when the pointer approaches
them, then change color when the pointer is poised to select them.
On the left, a midpoint highlights and the pointer shows that a coincident
relation  is possible at its current position. On the right,
the midpoint has changed color and the pointer shows that it recognizes
the midpoint  . |
