ABSTRACT:
A computer-aided design and drawing system having a dynamically oriented compass cursor is disclosed. In the interactive computer-controlled drawing system, a method and apparatus is disclosed for automatically generating and manipulating a dynamic compass cursor. The method comprises the steps of: 1) generating a compass cursor in a first orientation, the compass cursor being responsive to movement of a cursor control device; 2) selecting a geometrical element having a second orientation; and 3) selectively re-orienting the compass to the second orientation and maintaining the second orientation until a new orientation for the dynamic compass cursor is selected.
