This two-day course provides complete instruction on the use of CAD based design software for system design. Students will gain a functional knowledge of the most commonly used software, and leave the class able to use one for design and specifications purposes.
Topics include the menu system of the software, use of the sprinkler database for selecting and locating heads, completing and importing site drawings, assigning zones, manual and automatic pipe sizing, hydraulic calculations, and producing material and cost estimates.
Instruction will take place in a computer lab at Texas A&M University. Enrollment is limited. Students should be familiar with personal computers using the Windows operating system. No experience in computer-aided design is required.

The course will take place over two-days, 8 hours of instruction per day conducted in English. Instruction will take place in a computer lab at Texas A&M University. Enrollment will be limited so as to have no more than one student on each computer.
This course will provide a review of the irrigation system design process and complete instruction on the use of CAD (computer aided design) software for irrigation system design. The features and capabilities of commercial irrigation computer aided design software will be presented. Students will gain a functional knowledge of CAD software, and be able to use the software to design an irrigation system for a typical, large residence.
Topics include the menu system of CAD software, use of the sprinkler database for selecting and locating heads, completing and importing site drawings, assigning zones, manual and automatic pipe sizing, hydraulic calculations, and producing material and cost estimates.
Students should be familiar with personal computers using the Windows operating system. No experience in computer-aided design is required.
Note: Review of irrigation system design will be a lecture with students completing problems from the end of Chapters 2, 4, 5 and 7 of Landscape Irrigation Design. The remainder of the class will be hands-on computer instruction.
