Course DescriptionExamines customization of AutoCAD menu and Lisp files. Includes buttons, POP, image, screen and tablet sections, creation and implementation of user-defined AutoLISP functions, and basic file management techniques. Prerequisite: DRF 136. Audit available.
Intended Outcomes for the course
- The student shall develop knowledge and skills in the creation and edification of AutoCAD menu systems using basic to advanced customization principles.
- Demonstrate competency in understanding and implementing basic AutoLISP functions.
- Create AutoLISP programs that are task oriented and problem solving in nature.
Course Activities and Design
This course will be presented by means of short lecture/discussion sessions and laboratory projects. Individualized instruction will be provided while the student is working on assigned projects. Open laboratory time will be made available, and may be necessary to complete the given tasks.
Outcome Assessment Strategies
Individual and full class discussion; lab drawing assignments; exams; and final project deliverables may be used to assess outcomes.
