Drawing Standards - Introduction to CAD software – CAD user interface – Data input modes - Coordinate systems - Units and precision – Setting Limits and display units – Drawing templates - Features of GUI. Sketching basic geometric entities.
Sketching simple geometric entities: points, lines, circles, arcs, ellipse, rectangle, polygons, polylines, splines – Use of object snaps - Practice exercises using simple geometric entities.
Modifying drawings: Move, copy, rotate and offset drawings; Mirroring, Scaling, Trim, extend, erase, explode - Fillet and chamfering – Rectangular, Polar and Path array - Drawing exercise: Sketching and modifying 2D drawings.
Drawing properties: Line type, Line weight, Object properties – Hatch and gradient – Working with Layers - Dimensioning and annotations – Adding tolerance to dimensions – Working with text and tables – Sketching with blocks and groups - Use of attributes – Working with external references – Layout, printing and publishing drawings - Exercise involving sketching 2D orthographic views of 3D geometries with dimensions and tolerances.
Introduction to 3D - Isometric drafting - Conversion of orthographic projections of simple components into isometric views.
Project: Students have to complete a project involving creating orthographic views of the simple machine elements / assemblies such as centrifugal pumps, hydraulic cylinders, gear boxes etc. with dimensions following standard drawing practices using CAD software.
