This module aims to enable the student to communicate engineering information in the form of orthographic drawings.
The design process: The role of drafting in the design process. The role of engineering technicians in the design process. Drawing fundamentals, engineering graphics to international standards as an international language. ISO and ANSI standards.
CAD environment: Menus toolbars, prompts, graphic region, data entry (ribbon, menus, keyboard, toolbars and mouse).
Coordinate systems: Absolute/relative, rectangular/polar.
Drawing aids: Snaps, grid, ortho, coordinates, object snaps, grips, filters.
Geometric entities: Lines, polylines, circles, ellipses, arcs, polygons.
Sketching: Orthographic sketching, isometric sketching, line types, lettering, scale.
Orthographic drawing: 3rd angle projection layout of views, use of construction geometry.
Basic dimensioning principles: Conventions, datum features, baseline, continuous and aligned dimensions, dimensioning of holes and radii.
Output devices: Printing, print settings, exporting/printing to file.
Modifying geometric entities: Trimming extending, stretching, scaling, copying, moving.
Layers: Layer conventions, hiding, freezing, layer attributes.
Drawing templates: Defining and applying templates.
Entity properties: Attributes and colours by layer, by entity.
