6. 9.is when dimensions are drawn from one feature to a second feature, then a third feature is located relative to the second feature. The chain can continue with any number of features, with each one being located in relation to the preceding feature (5,12)
8. 1.command aligns the dimension with the angle of the object that you are dimensioning (7,12)
9. 4.mark (an item) for attention or treatment in a specified way (4)
10. 17.the decimal measuring system based on the meter, liter, and gram as units of length, capacity, and weight or mass. The system was first proposed by the French astronomer and mathematician Gabriel Mouton (1618–94) in 1670 and was standardized in France under the Republican government in the 1790s (6,6)
11. 15. a complete metric system of units of measurement for scientists; fundamental quantities are length (meter) and mass (kilogram) and time (second) and electric current (ampere) and temperature (kelvin) and amount of matter (mole) and luminous intensity (candela) (2,6,6,0)
12. 2.an aquatic or semiaquatic plant with arrow-shaped leaves and three-petaled white flowers (9)
14. 12.moving or operating in a single direction (14,12,0)
16. 19.is used when a series of parts consists of the same features or geometry but vary in dimension. Letters are used in place of dimension values, and the values are then placed in a table (7,12)
18. 18.is a machined feature in which a certain region of the workpiece is faced, providing a smooth, flat, accurately located surface (8,0)
19. 10.a drilled hole that has a flat-bottomed enlargement at its mouth (11)
20. 3. a bed or groove in a mechanical part to receive a key (7)

1. 8.is the drafting practice of using multiple units of measure in a dimension in the same direction of a feature. SolidWorks and many other CAD programs support dual dimensioning (4,12,0)
2. 14.a measurable extent of some kind, such as length, breadth, depth, or height (4,9)
3. 6.a pair of coordinates locating the position of a point in a plane, the first being the length of the straight line ( r ) connecting the point to the origin, and the second the angle ( θ ) made by this line with a fixed line. (5,10)
4. A point has dimension 0, a line has dimension 1, and a plane has dimension 2. For instance, a block of wood is 3-dimensional because you need three coordinates to specify any point inside (10,12,0)
5. 20. a group design object. It allows for the dimensioning of a radius with respect to an arc or circle. The dimension can be placed either internally or externally in relation to the circumference of the arc/circle (6,12)
7. 5.a small projecting knob or ridge, especially in a series around the edge of something (6,0)
13. 11.the ability or willingness to tolerate something, in particular the existence of opinions or behavior that one does not necessarily agree with (10,0)
15. 13.is a fine, dark, solid line with arrowheads on each end. It indicates direction and extent of a dimension. In machine sketches and drawings, in which fractions and decimals are used for dimensions, the dimension line is usually broken near the middle to provide open space for the dimension numerals (9,4,0)
17. 7.cut or wear away the part below or under (something, especially a cliff). (8)
