Pre Entry Introduction to COGO and CAD SURV 2009

Upon successful completion of this course, the student will be able to:

CAD

• Explain the various components of a typical survey plan.
• Explain the relationship of scale, paper size and survey area.,
• Manage CAD drawings.
• Explain fundamental CAD concepts including layers, text styles and entity editing.
• Produce simple digital plans using CAD lines, arcs, circles and text.
• Plot scaled CAD drawings.
• Create and use industry standard symbols within the CAD environment.
• Perform CAD inquiries for length, area, distance and direction.
• Use COGO routines for survey computations.
• Import and export digital plan data.

COGO / RPN Programming

• Create a COGO job, store point coordinates and compute traverse data.
• Compute inverses and solve areas from the coordinate database.
• Edit traverse data to correct typing mistakes and re-compute the traverse.
• Compute coordinate values by Bearing-Bearing, Bearing-Distance and Distance-Distance intersections.
• Transform coordinates by rotating, shifting and scaling points.
• Apply Helmert’s Transformation to determine the relationship between two coordinate systems.
• Shift a building’s location on a lot to conform to setback constraints.
• Create simple function programs to input from and output to the stack.
• Identify the difference between local and global variables.
• Create programs to ask for data input, process and then output the results.
• Apply conditional testing to make decisions within user programs.
