Advanced Radial Line Flashcards
A branch mitre is developed when?
Two or more oblique cones intersect, creating a primary opening and multiple secondary openings.
A full pattern must be created when developing a pattern for an oblique three-way Y-branch. True or False?
False
It is necessary to create a plan view when developing an oblique three-way Y-branch. True or False?
True
What kind of spacing is used to determine the stretchout of an oblique cone or branch fitting?
1/12 spacing
Describe a right cone?
A right cone can be defined as a cone with an apex that is aligned directly above the centre of its circular base.
Describe an oblique cone?
Is any cone with an apex that is not aligned directly above the centre of its circular base.
What must you do when developing a pattern for an oblique cone?
You must draw and use the elevation view
Does the vertical apex (VA) formula work for determining the vertical apex of an oblique cone fitting or branch?
No it does not work on an oblique cone fitting or branch
When laying out oblique cones, what are the element lines used to develop?
The views
When laying out oblique cones, what are the true length lines used to develop?
The pattern
What view is required when laying out an oblique two-way Y-branch?
An elevation view
What views are required when constructing an oblique three-way Y-branch?
Both plan and elevation views are necessary
Sometimes by coincidence the branch mitre line can share the same location as a point on the half plan view. True or False?
True
