Scales

You know the importance of using scales in the drawing, especially in the realization of the prospects for the years of selectivity.

We briefly review the use of scales, focusing on the financial perspectives. Definition


SCALE is defined as the ratio dimension drawn regarding its real dimension, ie E =

drawing / reality
If
the numerator of this fraction is greater than the denominator, it is a level of enlargement and reduction will be otherwise. 1:1 scale corresponds to an object drawn to actual size (full scale).


Example 1 Given a piece by its three dihedral view at 3:5, called for the 1:1 scale isometric.

The first step is knowing what the actual measurements of the part that shows in scale 3:5 (remember Drawing: Reality): Drawing


3 ---- Reality , 5 As


X X = measurement * 5 / 3 = 1.666666667 *

as Therefore, we must multiply each of the measures of the dihedral views given by 5 / 3, ie, 1.666666667

The second step is to establish what are the measures we use in our isometric perspective, in this example the scale to use is 1:1, so you will not have to change the scale.

Finally, we apply the isometric: 0.816

To simplify the process, we can apply both steps at once: 1.66666667 * 0.816 = 1.36. For our perspective

multiply by 1.36 each of the measures taken in the sights dihedral exercise. Example 2


are asked to perform isometric perspective of a 1:5 scale figure dihedral defined views which are at 1:10.

Actual Measurements: Drawing

1 ---- Reality 10 As


X X = measurement * 10 / 1 = measurement * 10

Measures in Perspective: Drawing
Reality ----
1 5 X
reality

X = true * 1 / 5 = reality / 5
isometric
: 0.816


All together, gives us:
10 / 5 * 0.816 = 1.632 1.632

multiply by each of the measures taken in the views dihedral exercise. Example 3


define a part of their view at 1:1, called isometric represent the 2:1 scale figure

Actual Measurements:
scale is natural, therefore no to do anything. Measures

perspective: Drawing

1 ---- Reality , 2 X


actually really * X = 1 / 2 = reality / 2
isometric
: 0.816


All together, gives us:
1 / 2 * 816 = 0,408 multiply by 0.408

each of the measures taken in the dihedral view of the exercise.


Example 4 Given the elevation and the left profile of a 3:4 scale figure, is asked to represent isometric drawing scale 3:2

Actual Measurements: Drawing

3 ---- Reality 4
measure X = X

as * 4 / 3 = measure * Measures

1.33333333 perspective: Drawing

3 ---- Reality , 2 X
, reality

reality * X = 3 / 2 = true * 1.5
isometric
: No reduction
being isometric drawing

All together, gives us:
1.333333333 * 1.5 = 2

multiply by 2 each of the measures taken in the dihedral view of the exercise.
