a) Size

b) Bisected

c) Coaxial

d) Body

3. The long rectangular boxes attached to extension lines, leader lines, or perhaps just floating near a size dimension are called _____________.

a) Datum indentification symbols

b) Modifer Boxes

c) Gemetric Control Boxes

d) Feature control frames

4. The geometirc tolerance that should be specified to indicate two surfaces should be coplanar is known as _____________________.

a) Parallelism

b) Flatness

c) Total runout

d) Profile of a surface

Answer 1

1. ANSWER (B) -Surface texture symbols are not related to GD&T

a) as in GD&T, datum symbols are the starting points where all other features are referenced from.

c) GEOMETRIC SYMBOL - a feature control frame is required to describe the conditions and tolerances of a geometric control on a part’s feature

d) feature control frame is required in GD&T to describe the conditions and tolerances

2. ANSWER (A) - size feature that has a center plane or center axis

3. ANSWER (D) Feature control frame - long rectangular boxes, attached to extension lines, leader lines or floating near certain dimensions.

4.ANSWER (B) Flatness, as condition of a surface having all elements in coplanar (one plane). tolerance zone defined by 2 parallel planes within which surface must lie.
