DRFT1331 Computer Aided Drafting

This is an introductory AutoCAD course for students in the Computer Engineering Technology program. The student will learn basic AutoCAD commands to be able to produce both schematic and printed circuit board drawings which will be required for subsequent courses in the program.

CTEC1184 Computer Concepts. Students will be expected to be completely proficient with Windows and generic Windows applications.

There is no text for this course as emphasis will be placed on using HELP available in the AutoCAD software.

There will be three tests in this course as follows:

• Test #1: Schematic Drawings a finished schematic will be drawn from a hand-drawn original. The drawing will incorporate 'standard' elements such as resistors, capacitors, and diodes as well as unique elements which the student will be required to draw as part of the test.
  Scheduled for Monday, Oct. 17, 2005, in class
• Test #2: Digital Circuits a finished schematic containing AND, OR, and other logic gates and digital chips will be drawn.
  Scheduled for Monday, Nov. 7, 2005, in class
• Test #3: Printed Circuit Boards the layout for a simple printed circuit board containing integrated circuits will be drawn from a schematic drawing.
  Scheduled for Monday, Dec. 5, 2005, in class
All three tests combined account for 50% of the final mark for the course. The other 50% will be from all assignments combined. Most assignments are to be done in-class with a few to be completed on a take-home basis.

Class Schedule for the Fall 2005 Term

Class 1: Monday Sept. 12

The class begins with a 'survival guide' to the environment used throughut the course including logging-into the computer network and invoking applications. In AutoCAD we will begin by looking at coordinate systems (UCS) and basic line commands (Commands: UCS, GRID, SNAP, LINE, UNDO, TEXT)

Class 2: Monday Sept. 19

Several drawing commands will be revisited (such as 'snap') and we will add dimensioning, text, and layers to our drawings. Plotting and scaling will be examined as well (Commands: TEXT, SNAP, LAYER, CHANGE, UNDO/ERASE, QDIM, PLOT). Assignment: Create a template for al further drawings

Class 3: Monday Sept. 26

Using commands learned in previous classes as well as a few new shape commands (e.g. arc, circle) we will draw electronic symbols required for schematic drawings including resistors, capacitors, and ICs. WBLOCKS will be used to make a library of component symbols used in upcoming schematic drawings (Commands: LINE, ARC, OSNAP, HATCH, WBLOCK, INSERT). Assignment: Create blocks of components - resistor, capacitor, diode, and transistors

Class 4: Monday Oct. 3

We will examine rules for drawing schematics, primarily concerning integrated circuits (e.g. pin numbering conventions, power supply pins). Commands already covered will be used. Assignment: Create a two drawings - one using an IC and a transistor and another using OP-Amps

Class 5: No Class on Monday Oct. 10

The college is closed for Thanksgiving. During the week, though, your schematic drawings will be available for pick-up in L-17 for review prior to next week's test.

Class 6: Monday Oct. 17

TERM TEST #1 in which a complete schematic will be drawn. Students are allowed to use their library of components created in class but will be required, during this test, to draw new symbols as part of the test.

Class 7: Monday Oct. 24

Test #1 will be returned and remedial issues will be covered as required in response to test results. We then move on to logic gates (AND, OR, and NOT). The rules for drawing digital schematics including logic busses and wire connectors will be covered. Again, a WBLOCK library of components will be developed Assignment: Create a library of basic logic symbols, and a drawing containing these symbols

Class 8: Monday Oct. 31

Complex logic drawings involving microprocessors and logic busses will be covered. Assignment: Create a drawing employing microprocessor components

Class 9: Monday Nov. 7

TERM TEST #2 in which a complete schematic will be drawn employing logic symbols. Students are allowed to use their library of components created in class but will be required, during this test, to draw new symbols as part of the test.

Class 10: Monday Nov. 14

Test #1 will be returned and remedial issues will be covered as required in response to test results. We then move on to look at printed circuit board design. Assignment: Create a library of basic PCB symbols including chip and component pads

Class 11: Monday Nov. 21

The basic rules for printed circuit board design including routing and spacing of traces is examined. Assignment: Create a drawing of a basic single-sided PCB with multiple layers for copper, component placement, etc.

Class 12: Monday Nov. 28

The basic rules for printed circuit board design including routing and spacing of traces is examined. Assignment: Create a drawing of a basic single-sided PCB with multiple layers for copper, component placement, etc.

Class 13: Monday Dec. 5

TERM TEST #3 in which a complete printed circit board employing ICs will be designed (roued) and drawn. Students are allowed to use their library of components created in class but will be required, during this test, to draw new symbols as part of the test.

Class 14: Monday Dec. 12

Test #3 will be available for pick-up.

• Doll House Controller PCB an example printed circuit board. Elements in violet are the silk-screen (top) layer.
• Assignment #8 Example Drawing - showing two layers: copper in white (layer 0) and the silk-screen layer in blue (layer 3).
• Assignment #10 Drawing - The starting point for the take-home assignment, pads for a Z-8 microprocessor, RAM, and ROM chips.
• Assignment #11 Drawing - The starting point for the SMT assignment.
