Assigning subpath attributes in a drawing

摘要

Techniques for assigning a subpath attribute to a subpath in a drawing are disclosed. One technique includes editing the drawing to define a current path having a current subpath, matching a previous vertex in a previous path with a current vertex in the current path, and assigning a current subpath attribute to the current subpath based on the vertex match. Another technique includes editing the drawing to define a current path having a current subpath, comparing the current subpath with a previous subpath having a previous subpath attribute, and assigning a previous subpath attribute to the current subpath based on the comparison.
