Tecnica% Terms
• Tee- intersecting pipes
• &a'i"s- is the length of a line segment from its
center to its perimeter .
• Intersecting %ines- Lines that have one and only
one point in common.
• Circ"m(erence - is the linear distance around
the edge of a closed curve or circular o!ect.

The Steps in Creating Tee Joint Stretch OutPattern
*. +ra$ line A vertically and line ) hori,ontally enough
space efore reaching the margin# using ruler /cm0
1. 2et the compass to 1.3 cm as the radius of thecylinder
/. +ra$ a half-circle using a compass $ith the
intersecting point of line A and )
4. +ivide the half circle into si5 e6ual parts using a /77-
877-977 triangle and numer it from one to seven

3. %ro!ect do$n$ards all the intersecting points of the
half-circle
8. Lay-out the cylinder sho$ing its front vie$ such that
its height is *7 cm
:. %ro!ect the : numered lines of the half-circle in to
the front vie$ of the line ) and at the ase line then
pro!ect another numered lines ac;$ard from si580 to
one*0 using a compass
<. (onnect the points to create vertical parallel lines
using a ruler

9. +etermine the circumference y measuring the lines
created y the numered parts from the half circle
*7. =rom the ase line set 1.3 cm up$ard and pro!ect to the
stretch-out pattern
**. (hec; the numer one *0 and seven:0 of the 1.3cmthen connect to the numer four40 form the ase line
*ote te n"m,er 2=6 i%e 3=5 an' 1=#
*1. Measure the distance of the numer 1 or 8 from thease line of the o!ect then pro!ect it to the stretch out
pattern for the dra$ing of the figure

*4. After pro!ecting their distance connect the line
from * to 4 # 4 to :# : to 4 and 4 to *
*3. Lastly# dar;en slo$ly the o!ect and the pattern

• In your lecture note oo; create other set of pattern using
parallel-line method follo$ing the same procedures and
steps discussed.
• 'ead and study the procedure in ma;ing a stretch-out
pattern for right cone using the radial-line development.
