Setting gaze direction when plotting an outline |
Scroll |
To set the gaze direction, you can use a guiding object or a vector.
You can use any straight-line or planar object as a guiding object. Straight-line and planar objects are listed in table Model object types.
The direction given by the rectilinear object is a straight line parallel to the object.
The direction given by a flat object is a straight line, perpendicular to the object.
To construct a vector, click the Construct Vector 
button to the right of the Direction field on the Parameter Panel. Vector vector construction.
The name of the selected object is displayed in the Direction field. If the directions is set using a vector, the word "Vector" is displayed in this field.
