Abstract: A server computer stores a database having a plurality of design files. A client computer selects one of the design files from the database at the server computer via the Internet. In response to this selection, the server computer instantiates in a memory thereof a copy of the selected design file. The server computer then determines in memory where the connection point of a feature represented by one object of the design file is coincident with or closely adjacent a connection point of another feature represented by another object of the design file. Once the connection points are made coincident or closely adjacent, the features represented by the objects are displayed on the display of the client computer with the connection points coincident or closely adjacent.
