| Question | Answer |
|---|---|
| a line that rises straight up from a level surface is | a vertical line |
| a sketch that shows the top, and side views of an object is an | orthographic sketch |
| to convert inches to millimeters, you multiply inches by | 25.3 mm |
| parallel, uniformly spaced lines indicating that a surface has been in contact with the cutting plane are called | section lines |
| the arrows of a cutting plane line indicate | direction of sight |
| why are letters placed at the end of cutting plane lines | for differentiation between sections |
| vertical lines are sketched how | from top to bottom |
| geometric figures with sides of equal lengths and of equal angle degrees are | regular polygons |
| another term for orthographic projection is | multiview drawing |
| according to the ANSI'S arrangement of views, the back view should be placed adjacent to the | left side view |
| within a CAD drawing, which of the following four scale types is the only system of units that uses fractional inches? | architectural |
| what is the name, color, and linetype of the default layer that allows you to begin a drawing within CAD? | 0, white, continuous |
| in CAD, when using the line command, if you make a mistake using the sub-option undo. | if you use the undo sub-option you do not have to exit the line option to use undo. |
| in a CAD system, how does the offset command work? | it constructs or copies an entity parallel to another entity at a specified parallel distance. |
| once a CAD drawing is complete, it is sent to a printer or a plotter. what is another name for the drawing being sent to the plot or print device? | HARD COPY OUTPUT. |
| in a CAD coordinate system, what system uses a distance and an angle from the last entered point | polar coordinates |
| when making a CAD drawing, the fillet command allows you to | round off a corner |
| what feature has been turned on if your CAD system automatically draws straight lines horizontally or vertically | ortho |
| when the ortho mode is activated in a CAD system, the crosshairs | move only vertically or horizontally |
| what command trims two intersecting lines a specified distance from the intersect and then connects the trimmed ends with a new angled line segment | chamfer |
| most CAD commands used to create lines and basic figures (entities)are located in what submenu | add or draw |
| when you are using a CAD system, three options for coordinate input are | absolute, relative, and polar |
| when you are using CAD to draw a 45degree line that is 3 units long, you should input | @3<45 |
| when you enter the circle command, autocad displays 3p/2p/ttr/<center point>. the brackets arround the center point indicate | that it is the current (default) option |
| when you are drawing in CAD, a connected sequence of line and all segments is treated as a single entity when | it is within the polyline command |
| if the distance from the subfloor to the ceiling joists is 108 in, then the ceiling height is | 9ft0in |
| the WBLOCK command writes a block file, the purpose of this function is that | WBLOCK writes a block as a new drawing file so it may be inserted as a drawing file. |
| spokes and ribs are not section lined when cut along their long dimension because | it would give a false compression of the thickness |
| in an aligned section, the | cutting plane is bent and drown through the arm or feature |
| when you are developing a block attribute, values may be set as | defaults |
| what command is used to save symbols so that they may be used in more than one drawings | WBLOCK |
| to edit the block attribute, which command is used | attedit |
| each vertex in a model is defined by | x,y,and z coordinates |
| which command creates a solid that rotates around an axis | revolve |
| which solids editing command can be used to take one solid from another | subtract |
