Assigning subpath attributes in a drawing

A method of assigning a subpath attribute to a current subpath in a drawing, including:

• editing a drawing containing a previous path having a previous subpath to define a current path having a current subpath, wherein the previous subpath has a previous subpath attribute;
• comparing the current subpath with the previous subpath based at least in part on a previous intersecting path that intersects the previous path at a previous vertex and a current intersecting path that intersects the current path at a current vertex;
• assigning a previous subpath attribute to the current subpath based on the comparison;
• and
• displaying the edited drawing.

A system for assigning a subpath attribute to a subpath in a drawing, including:

• a processor configured to:
• edit a drawing containing a previous path having a previous subpath to define a current path having a current subpath;
• match a previous vertex in the previous path with a current vertex in the current path, wherein the match results in a vertex match between the previous vertex and the current vertex;
• assign a current subpath attribute to the current subpath based on the vertex match;
• and
• display the edited drawing;
• wherein the processor is configured to match based at least in part on a previous intersecting path that intersects the previous path at the previous vertex and a current intersecting path that intersects the current path at the current vertex;
• and
• a memory coupled with the processor, wherein the memory provides the processor with instructions.

A computer readable storage medium encoded with a computer program product for assigning a subpath attribute to a subpath in a drawing, said computer program product comprising computer instructions for:

• editing a drawing containing a previous path having a previous subpath to define a current path having a current subpath;
• matching a previous vertex in the previous path with a current vertex in the current path, wherein matching results in a vertex match between the previous vertex and the current vertex;
• assigning a current subpath attribute to the current subpath based on the vertex match;
• and
• displaying the edited drawing;
• wherein matching is based at least in part on a previous intersecting path that intersects the previous path at the previous vertex and a current intersecting path that intersects the current path at the current vertex.
