Course Description

This course is about using the major features of AutoCAD to make graphic displays including basic geometric figures, orthographic views of three-dimensional objects, architectural and construction drawings, and pictorial drawings of three-dimensional objects. The major topics include the AutoCAD drawing, utility, file handling, text, editing, dimensioning, and plotting features. (Note: This course is 2 hours lecture and 3 hours lab. MAC computers are not recommended for ETD courses.).

Learning Outcomes and Objectives

  1. The student will demonstrate an understanding of the AutoCAD Main Menu by:
    1. selecting the correct command for specified tasks.
    2. beginning a new drawing.
    3. editing an existing drawing.
    4. plotting a drawing.
    5. selecting a file utility.
    6. exiting AutoCAD.
  2. The student will demonstrate an understanding of the AutoCAD commands by:
    1. specifying the correct mouse-selectable option needed for specific tasks.
    2. drawing lines from the Root Menu.
    3. editing existing features of a drawing.
    4. setting layers.
    5. plotting a drawing.
    6. drawing circles and erasing.
  3. The student will demonstrate an understanding of the keyboard to initiate AutoCAD commands by:
    1. listing commands needed to draw an object using various AutoCAD features such as LINE and CIRCLE.
    2. listing commands needed to perform editing functions including erasing, changing, and moving.
    3. listing commands needed to set layers and selecting available parameters for layers.
    4. listing commands needed to terminate a drawing session and deleting or saving the current drawing.
  4. The student will demonstrate an understanding of the AutoCAD commands and utility features to create prescribed drawings including applications in construction and architectural plans by:
    1. constructing and producing hardcopy drawings of specified geometric figures including tangent lines and arcs, tangent arcs, polynomials, circles, and ellipses.
    2. constructing and producing hardcopy orthographic drawings of specified three-dimensional objects.
    3. constructing and producing hardcopy pictorial drawings of specified three-dimensional objects.
    4. constructing and producing hardcopy architectural floorplans and site layouts to standard scales on standard size sheets.
    5. using the AutoCAD dimensioning features to add engineering or architectural dimensions to an appropriate drawing.
  5. The student will demonstrate an understanding of the various AutoCAD editing features to modify existing drawings and correct errors in drawings by:
    1. using the BREAK, EXTEND, and TRIM commands to modify the length of lines or modify the style of a line or other entity.
    2. using the MOVE and ROTATE commands to change the position of a line or other entity.
    3. using the COPY and MIRROR commands to duplicate drawing entities.
    4. using the SCALE command to change the size of any entity.
    5. using the CHANGE command to move an entity to different layer.
    6. using the ERASE and UNDO commands to delete erroneous entities.
    7. applying the editing features to architectural and construction drawing.
  6. The student will demonstrate an understanding of the AutoCAD plotting features to plot drawings on standard size layouts by:
    1. using AutoCAD LIMITS to adjust the graphics screen for a standard size of drawing sheet and a standard drawing scale.
    2. using the SCALE command to adjust a full-size prototype title block drawing to a specified, standard drawing scale.
    3. using LAYERS to select various pens, line styles and colors for plotting a drawing.
    4. using the SCALE and ROTATE options in the AutoCAD plot menu to plot drawings to various scales in both horizontal and vertical positions.

Criteria Performance Standard

Upon successful completion of the course the student will, with a minimum of 70% accuracy, demonstrate mastery of each of the above stated objectives through classroom measures developed by individual course instructors.
