20. Fundamentals of Engineering – Honors – ENGR H191 Lecture 5 - Cadkey19 Establish a File Name Format – i.e. EG H191 Proj #1 and/or EG H191 Dwg #7 Title Block Information

21. Fundamentals of Engineering – Honors – ENGR H191 Lecture 5 - Cadkey20 Parts and Patterns The borderline and title block are saved as a pattern file so that they may be added to a part file. A part file can be composed of one part and multiple patterns. The reverse is not true. Once you have done your title block you can use it again and again by simply changing the title, date, Dwg # and File Name.
