Chapter 8 Flashcards
A “warped surface” defines a sweeping straight line also called a generatrix.
False
A break line should be drawn coinciding with the hidden line, but never with a visible line
False
An Auxiliary view is always drawn
?
Auxiliary views are often used to produce views showing:
True length of a line
Point view of a line
Edge view of a plane
True size of a plane
Auxiliary views are used for all of the following, Except:
True size of the Dihedral Line
by using CAD, the task of finding intersecting lines and developmentals is greatly reduced.
False
An auxiliary view projects from the front view will always show which primary dimension the same as the top and the right side view?
Depth
reference lines, unlike folding lines are always parallel to the projection lines between views
False
reverse construction refers to the technique of creating the auxiliary line first then projecting to the principal views
True
An object that may be unfolded or unrolled to lay flat is call a developable object?
True
the angle between two planes is called the?
Dihedral angle
the gore method is a method of making approximate development of the double curved surface of a sphere by dividing it into equal planes with meridian planes and substituting cylindrical surfaces for the spherical surfaces.
True
Triangulation is the method of dividing a surface up into many triangles and transferring them into a development.
True
When a cylindrical shape is cut by an inclined plane the resulting shape is elliptical
True
Hidden lines are typically omitted from auxillary views
True
