What are the Drafting tools and equipments and their uses?

Answer 1

1. Drafting

+++

"Drafting" (or "draughting" my side of the Atlantic but I'll be consistent here!) means technical drawing, usually to design anything from a better mouse-trap to a big building or a ship.

'

The primary tools for manual drafting are the drawing-board, T_square, set-squares and protractor or its more sophisticated version, the drafting-machine which combines all those. Then pencils and pens of appropriate grades, rules, dividers and compasses.

'

You ask uses:

'

T-square and set-squares for drawing lines horizontally and (normally) at 30º, 45º, 60º and 90º to those; protractors for setting out other angles. Rules obviously for lengths.

'

Compasses for drawing circles and circular arcs, both as drawing features and in geometric constructions; dividers as an aid in measuring.

'

HOWEVER.... The above is for manual drafting. Nowadays almost all professional and a good deal of amateur drafting is carried out by computer, using special 'CAD' ('Computer Aided Drafting') software packages that can be extremely powerful and versatile but demand very considerable cost in time and effort to learn to use them. Many of these allow the drawing to be saved as a file readable by Computer-Aided Machine-tools such as plate profile-cutters, lathes and milling-machines.

AND... This is vital if you need the information for possible career choice. Irrespective of manual or CAD, you must still understand what you are designing and how to design it. Merely learning to make a smart drawing is not learning to design!
