should measure 7″ × 10″ if you are using ″
1/2″ borders on a 8-1/2″ ″ × 11″ drawing ″
sheet and the title block measures 1/2″.
Refer to Chapter 5 on how to prepare a
drawing sheet.
3. Allow 1 ″ 1 1 spacing between views. ″
4. To locate the front view, add the width of
the front view, 1″ spacing between views, ″
and the depth of the right view.
Subtract this total from the horizontal
width of the working surface (10″).
Divide this total by 2. This will be the
starting point for laying out the sheet
horizontally.
Using the object shown in Figure 9-20,
for example, the calculations are as
follows:
Width of front view = 5″
Spacing between views = 1″
Depth of right view = 1-1/2″/
Total = 7-1/2″
Width of working area = 10″
Total width of views = –7-1/2″/
Total = 2-1/2″
Divide 2-1/2″ by 2 = 1-1/4″ ″
This is the distance measured from
the left border to locate the starting point
for drawing.
5. Measure in 1-1/4″ from the left border ″
line. Draw a vertical construction line
through this point.
6. From this line, measure over a distance
equal to the width of the front view. Draw
another vertical construction line. See
Figure 9-21.
7. The same procedure is followed to center
the views vertically. The height of the front
view and the depth of the top view are
used. A 1″ space will separate the views. ″
Add these distances together. Subtract the
sum from the vertical working space (7″).
