M2: Explain how the range of commands used to produce CAD drawings can
impact drawing production.
Impacts of CAD on drawing production
CAD commands can influence the output of drawings by making functions deemed unlikely
without using such commands. An example would be to use the computer mouse to move
and rotate a design at any angle giving a 3D representation without having to start another
drawing. This saves time and makes the process more efficient than manual drafting. In fact,
CAD can automatically transform the drawing precisely to such dimensions by entering in the
dimensions. This function reduces the likelihood of human errors. By doing this the drawing
finished would have the accurate measurement necessary. Another way CAD commands can
affect a drawing is by reducing working time and improving precision.
Many impacts of CAD on development drawings such as:
• Modification commands like moving, copying, cutting, etc. can speed up production
drawing.
• Utilisation of templates and printing techniques to produce quick, precise physical
copies of drawings.
