Acitivty 1.3.1 COORDINATE DRAWING
ACAD3
1. Begin a new drawing called ACAD2(remember to include your initials)
2.Start the drawing in the lower left hand corner at 1,1. Try to incorporate all three methods-absolute, relative, and polar-to enter the points.

Activity 1.4.1 TRIM AND OFFSET
ACAD4
1.begin a new drawing called ACAD4
2.draw two 3.5 unit quares beginning at point 1,1 and 7,1
2.use the offset and trim command to complete the drawing as shown
3.when complete save the drawing

ACAD4

Introduction to AutoCAD Quiz #1.

Feb. 2-5th 2010, week one

February 2, 2010

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.
