A T-Square is a drafting tool for drawing straight horizontal and vertical lines, relative to the edge of the drafting board.
when you sketch you proportion a picture of something and a sketch is always black and white. When you draw you create a picture of something without proportioning it and you usually color it . When you construct a geometric figure you use straight lines to form a closed figure :)
Placing a question mark at the end of a phrase does not make it a sensible question. Try to use a whole sentence to describe what it is that you want answered.
A protractor.
Hidden edges
They simply used straight edges of wood.
Ruling staight lines I guess... I have to write information on this for my homework, so I'm thinking you'd use it to rule straight lines on a material such as plastic or wood, or a step further, drawing lines for graphic design.
for drawing inclined lines
One important element of drawing is understanding and practicing the use of line work. Lines can convey shape, texture, and depth, and mastering different types of lines can greatly enhance the impact of a drawing.
You would use lines and ovals.
The mini-drafter is a versatile tool and can be used for almost everything. It can be used to draw parallel lines, perpendiculars, inclined lines of any degree with unmatched speed. it consists of one long scale and one small scale and the scales are shaped in 'L' shaped and by a mini drafter we can do 3 kinds of works : 1) drawing of lines 2)drawing perpendiculars for the lines 3)we can use that as a protracter simultanously
Hatching is the use of fine, parallel lines drawn closely together, often rapidly drawn, to create the illusion of shade or texture in a drawing. Distance may be varied to allow more or less white space between the lines, or lineweight varied to thicken the darkness of the lines. Often used in pencil sketching and in pen-and-ink drawing.
Arrows - up, down, left, right or combinations of same for diagonal lines. Mouse comes in handy for drawing, too.
filter needle
The back saw is for cutting short accurate lines in wood.
Because when you use the proper paper lines it will help you when you are older and and now also it will help you in your drawing technique.
line drawing- use of straight lines hatching- use of parallel lines drawn close together to create a shading effect cross hatching- hatching at 90 degrees scribbling- random scribbles
