Discuss the capabilities of CAD systems.

Question

What will be an ideal response?

Answer 1

CAD systems utilize all the principles and applications of drafting techniques, engineering data, and information generally found on drawings produced by conventional methods. CAD can make every type of drawing that can be done manually.

CAD scaled drawings may be enlarged or reduced and automatically dimensioned to provide necessary manufacturing information. Cross-hatching for sectional views is produced by selecting the correct cross-hatch lines for the part material, choosing the desired angle for the lines, and defining the area to be cross-hatched. Single, multiple, and/or auxiliary views may be drawn using CAD. A completed drawing may be reproduced in black and white or color, stored in memory, recalled at any time, and edited for changes, corrections, or additions.

Details are generated by zoning in on a feature and zoning out to view the drawing in full. Notes and straight, slant, and architectural style letters and numbers may be selected and placed at desired locations on drawings.

CAD has several claimed advantages over manual drafting. CAD is said to be more accurate, faster in many instances, neater, and more consistent in quality. Some of the most important advantages are in the areas of immediate retrieval, revision, and storage of drawings.
