Detecting and displaying screw threads e.g. in CAD system, by retrieving data set stored in database and using to produce three-dimensional model of thread

摘要

Characteristic parameters of the thread are stored in a database. The method involves generating a data set containing the required parameters for describing the thread geometrically. The data set is stored in a database. The data are retrieved by a user and a three-dimensional model of the thread is produced, e.g. using a CAD system.
