Drafting Technology Course Descriptions

CADD 2341. Computer Aided Drafting L (2-4-3). Study and application of coordinate systems, drawing editor. methods of entering commands. interface devices, i.e. keyboard, mouse and dialogue boxes. Create prototype drafting by establishing named layers with colors and line types. Use of layer controls to increase productivity. Learn and apply basic commands when creating a drawing using OSNAP, GRID, units, LIMITS, EDITING. \modifying AND PART OF CONSTRUCT, VIEW, LINES. ARCS,. CIRCLES, POLYGONS, and other basic text commands.

CADD 2342. Computer Aided Drafting IL (2-4-3). Continuation of CADD 1380. Completion of assigned drawing will be coordinated with the following commands: COPY, MIRROR, ARRAY, LTSCALE. CHANGE, CHPROP. Create or revise previous prototype drawings using units, LIMITS AND SCALE FACTORS; TEXT STYLES, DIM STYLES, DIMVARS, PLOT, CHANGE UNITS, PLINE, DLINE, ELLIPSE, STRETCH, PEDIT, EXPLODE, INQUIRY COMMANDS, FILLET, CHAMFER. OFFSET, DIVIDE, POINTS, INSERT, SELECTION SETS, SOME BLOCK AND BLOCK ATTRIBUTES, GRIP EDITING, and others as needed to complete assigned project.

CADD 2343. Computer Aided Drafting UL (2-4-3). Continuation of CAD 2342. Emphasis will be placed on self-reliance for learning new CADD skills and completing assigned projects to simulate actual job situations. Continue with increasing awareness of uses of drawing DATABASE, USE ADVANCED CONCEPTS OF BLOCKS, A-ATTRIBUTES, EDITING, TEXT, VARIABLE SETTINGS, DIMENSIONS, SECTIONING DRAWINGS, PICTORIALS (ISOMETRLC AND 3-D), X-REFERENCES, PAPER SPACE, CREATING VIEWS AND DISPLAYS, WIRE FRAME MODELING, AND SURFACE MODELING USE @ IN AutoCad. Continue to improve skills in plotting and media applications. Prerequisite: CADD 2342 or equivalent.

CADD 2350. Microstation. (2-4-3). Introduction to GUI, Graphics User Interface program. using dual monitors, covering elements placement, manipulation and modification, element- attributes, coordinate systems, construction techniques. text rotating elements, creating cells and cell libraries, multiple lines, dimensioning (2-D and 3-D), reference files creation and use, complex chains and shapes, importing, modifying and exporting different file formats and developing user commands with English instructions.

CADD 2360. External Applications. (2-4-3). Using AutoCAD SQL (Structured Query Language) Extension (ASE) software and database when a drawing is made, create a formatted data base report. This report may be used by managers, purchasing, inventory control, development of geographic information systems (GIS) and cost estimates. Development of competencies in required operating systems ((MS DOS, Netware and Windows) will be incorporated into program to assure students will have needed skills. Prerequisites: CADD 2330 or equivalent. (RW)

CADD 2370. Special Projects. (2-4-3). Customized to meet needs of individual students. May include customizing work station pipe drafting, GIS, golf course design and telecommunication systems using English language programming. This course will be designed to develop individual student's real work experience by contracting with industry partners. This real work experience will be a beneficial CAPSTONE experiences for each student. Contact between student and professionals in industry will prepare the graduate for transition from academic environment. Prerequisites: CADD 2342 or permission of coordinator. (RW)
