2D Drawing PDF Learn how to use computer-aided design (CAD) software like AutoCAD and SolidWorks to create 2D vector-based drawings for architectural, industrial design, and engineering projects.
2D CAD systems such as AutoCAD or MicroStation replace the paper drawing discipline. The lines, circles, arcs, and curves are created within the software.
It is down to the technical drawing skill of the user to produce the drawing. There is still much scope for error in the drawing when producing first and third angle orthographic projections, auxiliary projections and cross-section views.
A 2D CAD system is merely an electronic drawing board. Its greatest strength over direct to paper technical drawing is in the making of revisions.
Whereas in a conventional hand-drawn technical drawing, if a mistake is found, or a modification is required, a new drawing must be made from scratch, the 2D CAD system allows a copy of the original to be modified, saving considerable time.
2D CAD systems can be used to create plans for large projects such as buildings and aircraft but provide no way to check the various components will fit together.
