G1. Course Outcomes: Upon completion of this course, the student will be able to identify, layout and complete various technical drawings according to industrial standards using CAD commands to include detail and assembly drawings. At all times you will be expected to learn not only the "how to do" aspects of the different techniques but also the "what is it" and "why does it work" aspects. We will use the Pro-Engineer software package as the primary CAD tool in this class. The package is a powerful tool to enable you to achieve the learning objectives listed above.
G2. Program Competencies:
Upon graduation with an Associate in Applied Science degree in Computer-Aided Drafting and Design, the graduate will be able to: PC 1: Demonstrate proficiency in the use of the latest 2D and 3D CAD design software and equipment. PC 2: Demonstrate knowledge of design techniques and principals involved in the production of technical plans, drawings, and models. PC 3: Create accurate detailed drawings using CAD design software and equipment. PC 4: Demonstrate critical thinking, communication, and problem-solving skills to perform effectively as a design drafter. PC 6: Solve engineering and design problems by applying fundamental knowledge of engineering concepts and manufacturing processes.

- Attendance Requirement (as per Iroquois Central School District policy):
Students are strongly encouraged to attend each class. Students are also graded on participation.
- Classroom Expectations:
The following guidelines will create a safe and creative learning environment for all student to thrive.
- To come to class on time.
- To be attentive and engaged in class.
- To refrain from using laptops, cell phones, and other electronic devices during class.
- To spend an adequate amount of time on the work each week, making an effort to solve and understand each problem.
- To engage with both the abstract and computational sides of the material.
- To seek help when appropriate.
- Topical Outline:
- Assembly - A structured combination of parts and possibly other assemblies (subassemblies).
- Associative Relationship - The relationship between objects that reference each other. When changes are made to the design in one area of the product, all of the areas are updated to reflect that change.
- Base Component - The component in an assembly that is referenced by all of the subsequent components, either directly or indirectly.
- Child - An object, such as a part or a feature, that is dependent on another object for its existence. See also parent.
- Collector - An interface tool for collecting single or multiple references when defining geometry.
- pro - file See configuration file.
- Configuration file - A text file that contains default settings for many Pro/ENGINEER functions. Default environment, units, files, directories, and so on, are set when Pro/ENGINEER reads this file on startup. A configuration file can reside in the startup directory to set the values for your working session only, or it can reside in the load directory to set values for all users running that version of Pro/ENGINEER. Use the Utilities > Options dialog box to view and edit configuration options.
- Constraint - A limitation that states that one object has a definite geometric relationship to another.
- Dashboard - The interface environment used when defining or editing geometric features. Each feature type employs a specific dashboard.
- Datum - A point of reference in space that Pro/ENGINEER uses to calculate distances. A datum can be an actual point, a plane, or a curve, but it has no actual thickness.
- Design Intent - An overview of component interaction toward a common purpose.
- Detailed view - A drafting view that shows a small area of another view at a larger scale. This process places a box and a note around the detailed area on the parent view and creates the new detailed view to a new scale.
- Drawing file - A 2D mechanical drawing derived from a 3D model that enables measurements to be interpreted.
- Driven dimension - Dimensions in a drawing file derived from the 3D model. Driven dimensions reflect changes to part or assembly geometry, but you cannot modify their values from the drawing. The association is one way: from the model to the drawing. See also driving dimension.
- Driving dimension - Dimensions that when modified in the drawing are also modified in the 3D model from which they originated.
- Fully constrained - In an assembly, a part with constraints defined to another part on more than one side.
- Feature - An element of a designed object such as a hole, protrusion, or round.
- "In session" - file A file that is in memory, but may or may not be visible in a window. For example, when you open an assembly, all associated part files are in session, although they may not all be visible as separate, open files.
- Menu Manager - The floating menu bar that expands as necessary to provide prompts through options, as objects are created or modified.
- Mode - A Pro/ENGINEER environment in which closely related functions are performed, for example Part mode and Assembly mode.
- Model Tree - A list of every feature in a part or assembly file, including datum.
- Packaged component - Components that are partially constrained or not constrained to other parts in an assembly.
- Parametric relationship - The relationship between objects that are interdependent for dimensions or shapes.
- Parent - An item in a model that has other items (children) dependent upon it for dimensions or shapes. If a parent is deleted, all dependent items (children) are deleted as well. See also child.
- Part - A component consisting of features that can be separated from or attached to an assembly.
- Partially constrained In an assembly, a part with costraints to another part on only one side, or a part that is placed but unconstrained. Also called a packaged component.
- Projection view - A drawing view derived from one side of a solid. relations Associativity between dimensions that is retained as the dimensions change.
- Section - A 2D outline in Sketcher mode of a 3D entity. The entity may be a solid, or it may be an area where material has been removed, like a cut or a channel.
- Shell - A feature that hollows out a solid to a given wall thickness.
- Shortcut menu - A menu that appears when you select an item or screen with the right mouse button. The shortcut menu contains commands pertaining to the item or screen that was selected.
- Sketcher - A 2D drawing mode within Part mode used to draft dimensioned lines and arcs to create solid parts.
- Strong dimension - In Sketcher, a dimension to which you have given a value. See weak dimension.
- Top-down design A method of designing a product by specifying top-level design criteria and passing those criteria down from the top level of the product’s structure to all of the affected parts.
- View - The position of a part or assembly in the main window.
- Weak dimension - In Sketcher, a dimension that Pro/Engineer adds to an angle or a line automatically. The weak dimension is an approximation, shown in grayed lines. You convert the weak dimensions to strong dimensions by entering the accurate values.
- Witness line - A line that indicates the start and end of a dimension.

- Collect Information

- Brainstorm and Analyze Ideas
Begin to sketch, make, and study so you can start to understand how all the data and information you’ve collected may impact your design.
- Develop Solutions
Take your preliminary ideas and form multiple small-scale design solutions.
- Gather Feedback
Present your ideas to as many people as possible: friends, teachers, professionals, and any others you trust to give insightful comments.
Reflect on all of your feedback and decide if or to what extent it should be incorporated. It is often helpful to take solutions back through the Design Process to refine and clarify them.
