Abstract
A method, apparatus, article of manufacture for defining a precision drawing point is disclosed. The method permits the definition of temporary interesting points anywhere in the drawing space. Each temporary interesting point allows the definition of a set of candidate alignment lines, all intersecting at the temporary interesting point. When the user moves a cursor within a snap distance of one of the set of candidate alignment lines, an alignment line is displayed. The precision drawing point is then defined on the alignment line. The drawing point can be defined when the cursor is within a snap distance of one of a set of pre-settable snap distances from the temporary interesting point. Alternatively, the drawing point can be defined by selecting a second temporary interesting point associated with a second set of candidate alignment lines, and positioning the cursor within a snap distance of one of the second set of candidate alignment lines. The drawing point is then defined as the point in the drawing space where the first and second alignment lines intersect.
