Geometric Constructions In Drafting

This unit introduces the student to geometric constructions and the application of them. The students will learn how to use the common drafting tools to create such things as circles, arcs, lines, and squares to specific sizes and drawn correctly in relation to other objects. This unit relates to board drafting, not Computer-Aided Drafting (CAD) although the skills, vocabulary and understanding taught in this unit are necessary to students learning CAD. Some instructors in technology and drafting may wish to skip any such units involving board drafting using pencils and paper. However it is important for students to learn the definitions of various constructions and geometric relations in their simplest forms. Drawing these lines, circles, arcs, or squares on paper using the correct tools and procedures enhances a student's learning of difficult concepts such as the parts of a circle, tangency, circumscribed, inscribed, equilateral, isosceles, concentric, etc. Students spending the time going through this short unit will learn CAD faster and be able to apply the concepts to complex geometry and create other projects. The final products of this unit are three specific drawings assigned by the instructor for the students to create and have graded by the instructor. The skills learned would apply to almost all fields of Engineering and Design, such as Mechanical or Electrical engineering.

Orthographic Projection

This unit will cover fundamental drafting techniques used to create orthographic drawings. Often referred to as multiview drawings, orthographic drawings represent different views of a single part that represent the unique features of the part. The technique of orthographic projection is used to transfer similar information from one view to another.

These types of drawings may be produced using manual drafting tools, such as a drafting board, T-square, drawing angles and pencil. They can also can be drawn on a computer using various Computer Aided Drafting software programs.

Engineers and drafters in Mechanical, Electrical and Product Design as well as other areas must understand this fundamental concept to be successful in their fields.

Introduction to the CAD Program

Students will be introduced to the concepts of a Computer Assisted Drafting (CAD) program. Students will immediately experience an appreciation and understanding of how CAD can make processes faster and with more accuracy than hand drafting. The students will be shown the interface of a common CAD program and identify the locations and functions of groups of tools, settings, command lines (if appropriate) and other parts of the screen. Students will immediately learn how to input, either with a keyboard or mouse and create various drawing objects such as lines and circles. Element creation and basic editing skills will be learned.

Most skills can be transferred from the CAD program shown (AutoCAD) in this unit to other CAD programs such as SolidWorks or Inventor. The skill sets and progression of skills would be followed no matter which software title is chosen. It is anticipated that instructors could take these lessons and adapt the presentation as necessary to the other CAD programs in use at their educational institution or computer lab.

Students will record their learning competencies on worksheets such as "Parts of the CAD screen". The will edit an office floor plan. They will create and print their first drawing, a sample of all the 2D drawing elements in their CAD program of choice. Finally they will complete a simple drawing "Notched Plate" and print this as well.

After successful completion of this unit, it is suggested that the instructor would progress to the units entitled "Setting up parameters in CAD" and "Cartesian Coordinate Systems" also in the "Engineering and Design 1/2 Group."

The skills learned would apply to almost all fields of Engineering and Design, such as Mechanical or Electrical Engineering.
