What is the foundation of Parallel line development
Element lines
An object not developed with simple parallel line development is a
Boot tee
You can develop patterns for spherical objects with parallel line development
True
To properly develop a parallel line development pattern you must have the true lengths of the
Element lines
Primes in parallel line pattern development are names used to identify an
Extra element point
Parallel line development uses the same steps for any object developed with this method
False
The perimeter of the pattern is found where
Plan view
Element line spacing on the stretch out is best developed by
Calculating and measuring
To see what the actual base plate would look like you could develop a
Auxiliary view
How many divisions are typically used to divide smaller circles
12
When laying out a y stub pattern it is necessary to have
Both side and end view
There will be a hidden line in the side elevation view of an on the center pipe y
False
Y pipes are always laid out at 45
False
Hole pattern spacing around the main cylinder is taken from
End veiw
Stub strtchout on a rectangular y is calculated by
2L+2w
Extend element lines from the side elevation view to develop the
Hole pattern
Is the pipe diameter critical when developing a y pipe stub
Yes
Construction and element lines help us develop
Stub stretchouts, mitre lines, hole patterns
When laying out a tee fitting you start by drawing what veiw
Side view
Corresponding element lines from the end view and side elevation create
The mitre line
When lettering or numbering the 12 equal divisions it is best to start
At the seam
If the stub has the same diameter as the pipe will the stepped off distance for the hole pattern be
Equal
When laying out a hole pattern element lines must be extended from
Elevation view
When laying out just the stub pattern the end view is all that is required
True
