FEB 2ND 2010..
Introduction to blog spot and CAD!
Introduction to technical drawings:
BASIC DRAWING EQUIPMENT
- Drawing pencils (range from 2B TO 2H)
- Compass
- Protractor
- T-Squares (drawing horizontal lines)
- Set Squares (accurate angles)
EXPLODED VIEW
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.
ORTHOGRAPHIC PROJECTION
Third Angle Projection
Orthographic drawing is a way of drawing a three dimensional object. Normally the object is drawn as three separate, related views - Front View, Side View and Plan View.
Dotted lines represent ‘hidden detail’. In this case they represent the hole, through the block/object.

FEB 3RD 2010
Learned the three different types of points on CAD
Practiced those three different types of points on the program
ABSOLUTE
Points from origin
EG- 2,1 4,1 4,4 2,4 2,1
RELATIVE
Points from the previous number
2,1 @2,0 @0,3 @-2,0 @0,-3
POLAR
Points and then angle
2,1 @2<0 @3<90 @2<180 @2<270

Practiced more on CAD. Learned how to enlarge the grid and practiced polar co-ordinates. We also learned how to use the Offset and Trim features in CAD.
Examples above ..
