In todays class we learned about; Introduction to technical drawings.

Moodle: Post number 4;
Basic Drawing Equipment 1-3, (highlights)
BASIC DRAWING / OFFICE EQUIPMENT - 1
--drawing Pencils- a range from 2Bto 2H
--A refillable pencil-is very useful especially if you are constructing a drawing that needs a constant thickness of line. (disadvantages: the refillable pencils are relatively expensive and so are the refills. Also, the leads tend to break more easily.)
--Compass
--Ink fountain pens
--A protractor

BASIC DRAWING / OFFICE EQUIPMENT - 2
--A fine pen (colour - normally black)
--T-Squares -are use to draw horizontal lines.
--Set Squares-are used to draw accurate angles.
--Board clips-are used to hold the drawing paper in position.
--A ruler-is possibly one of the most important pieces of drawing equipment.

BASIC DRAWING / OFFICE EQUIPMENT - 3
--Circle templates
--A craft knife-is used to cut out card shapes
--scissors
--Pencil sharpeners
--A craft knife

EXPLODED VIEW-part of techincal drawing.

Exploded views are often a good way of showing detail. The drawings below show two types of similar pens. One is a fine line felt pen used for drawing precise, fine lines. The other is a fountain pen and it is used to write letters etc.... Both pens have been drawn as ‘exploded views/drawings’. In an exploded drawing the pens are drawn with all their parts disassembled (taken apart). It is important to recognise that all the parts are in line with each other, drawn usually along a centre line which is drawn through the centre of the design.
