SYSTEM AND METHOD FOR ASSOCIATIVE SOLID SECTIONING DURING DRAFTING OF GEOMETRIC MODELS

A system and method for associative solid sectioning during drafting of geometric solid models is shown which automatically generates a section view of a solid model by receiving input from a user including at least one feature the user desires associated with a section line, associating selected edges of the designated feature(s) with corresponding section segments, creating additional section segments if necessary, trimming all of the section segments together to form a section line which is then associated to the solid model. A section view is then created based on the associated section line. Moreover, the section line of the system and method of the present invention automatically tracks an associated feature if such feature should change during editing of the solid model by determining that the feature has changed, automatically adjusting any section segments which cross the changed feature, regenerating the section line from the adjusted section segments, and updating the section based on the regenerated section line.
