how do you do scale drawings?

Answer 1

Firstly take measurements of what you want to draw e.g. a simple cube that is 100 cm x 100 cm x 100 cm. A full scale drawing would require you to draw the cube on paper as 100 cm x 100 cm x 100 cm.
If you want to 'scale', you would then redraw using new measurements. So, a 1/10 scale drawing would mean that you would redraw the cube on paper as 10 cm x 10 cm x 10 cm. A 1/20 scale would be 5 cm x 5 cm x 5 cm. The same concept holds for all scale drawings...

Answer 2

You have to work out what scale you want to draw to. For example, if you wanted to draw a building that is 30 metres high, you could use a 1:5 scale: 1cm= 5 metres, you can scale up (1:2.5) or down (1:10) from there, and you can use combination of measurments.

Answer 3

If the part you want to draw is 1000mm long and you want to draw at 1/10th just divide the 1000 by 10 - easy!

If you are drawing using a C.A.D. software package you can set it up so that the scale will draw at whatever you want.

If you are drawing manual, you used to be able to but special scale rules. I'm sure that you can still get them - have a look on the tinternet.

Answer 4

I assume you mean to scale your drawing up!?.
Get a piece of A4 acetate paper and draw a grid 1*1 centimetre square, covering the whole sheet.
Place this over your original drawing, picture etc.
Now take an A3 sheet of acetate paper and do a 3*3 cm grid.
Place this sheet over an A3 sheet of plain paper.
Using the smaller grid as reference, use this as a guide to transferring the drawing onto the A3.

Answer 5

Work out what scale you are using and just go ahead with the conversion from 100% for the original to the scale.

Answer 6

Draw a grid on what you want to copy from and then draw a smaller grid with the same number of size relative squares on a blank sheet of paper, then copy square for square.

Answer 7

There is a great little gaget out there designed for just this sort of thing (unless you need it for really accurate technical drawing), called a parallelograph.

It's basically a parallelogram with a tracing arm and a drawing arm and you can alter it to fit the size you need.

I'll see if I can find one on the web...

Answer 8

Draw a grid over picture. Take each peice of the grid and either scale up or down(enlarge squares size/reduce squares size).
The redraw what is inside.
Or you could scan picture on PC, then enlarge/reduce digitally.

Answer 9

Make a grid on tracing paper, place the grid over the drawing you want to copy, then draw another grid of small squares making sure there are the same number. With another peice of tracing paper, place it over your new grid and copy the picture.

Answer 10

Well if you are drawing from a photograph, make a grid on it and make one on your paper, so you can perfectly scale each square.
