Study Notes
CAD Concepts and Terminology
- CAD stands for Computer Aided Design, a technology for creating technical drawings electronically.
- CAM stands for Computer Aided Manufacturing, integrating CAD designs into manufacturing processes.
- Extension lines in CAD are characterized as thin, used to indicate dimension.
Drawing Techniques and Commands
- The PAN command enables movement of the drawing view on the screen for better accessibility.
- The LIMITS feature defines the workspace dimensions where designs can be created.
- The EXTEND command allows lines to be lengthened to meet specified objects, enhancing precision.
Standardization and Accuracy
- ANSI (American National Standards Institute) is responsible for establishing dimension standards in the U.S.
- Accuracy in CAD drawings is improved by utilizing the SNAP feature, ensuring precise placement of elements.
Fundamental CAD Elements
- Basic figures in CAD, such as lines, circles, and arcs, are referred to as Draw Commands.
- A GRID displays a uniform pattern of dots on the CAD screen, serving as a reference for alignment.
- A POLYLINE command allows drawing a series of connected lines and arcs as a single object with specified width.
Modifying and Customizing Drawings
- The DIMENSION STYLE command allows adjustments to dimension properties, including lines, arrows, and text settings.
- The SCALE command resizes selected objects proportionally across multiple dimensions: x, y, and z.
- The DIVIDE command places evenly spaced points or blocks along an object's length or perimeter.
Viewing and Presentation Features
- The ZOOM command remembers the last five zoom views, allowing quick navigation through previously viewed sections.
- ORTHO mode automatic setting restricts drawing to straight horizontal and vertical lines for ease of alignment.
Constructing & Extruding Shapes
- Extruding a profile converts a 2D shape into a 3D form by adding thickness.
- A surface is defined as a flat or non-flat element created from a curved line, expanding design capabilities.
Symbolism and Notation
- The letter 'n' represents Intersection while 'u' denotes Union or Join within the context of CAD.
- Relative Polar coordinates, indicated by the '@' sign, facilitate the precise placement of points using a relative system.
Additional Notes
- The term "hard copy" pertains to documents produced by a printer or plotter, allowing physical copies of digital designs.
- The command BLOCK compiles a single entity from multiple elements for repeated usage in a drawing.
- Closing a polygon involves executing the command by typing 'C', linking the last point back to the initial point.
