This article marks the trial introduction of what I hope will become a regular feature in the ACADIA Quarterly, a forum for the debate of opposing viewpoints on various CAD issues. In each issue, I intend to present a controversial, CADrelated topic, and argue it, pro and con, with another ACADIAn. It is my hope that the discussions in this article will cause us all to form knowledgeable opinions on subjects we hadnit previously considered, examine our views on debatable subjects more critically, make us better informed about differing viewpoints, and perhaps even change a few minds.
