1. Grips are used to ________
a) hide the drawing
b) modify operations
c) stop an object from moving
d) lock an object to fix the properties
Explanation: Grips are small boxes that appear at specific locations on an object when clicked on it. Grip command is used to modify the objects, such as Move, Rotate, Scale and Mirror. Grips are ON by default
2. Command used to bevel the corner at specified distances of intersecting lines is _________
a) Join
b) Fillet
c) Chamfer
d) Align
Explanation: Chamfer is the command which works on two lines or a single polyline to create a beveled edge. This command is not directly shown on the modify panel. Designer has to click the triangle on the right side of the fillet icon, to get an option of fillet and chamfer
3. A hexagon drawn with a polygon command has six lines. If you try to delete one of its lines, whole hexagon will be deleted. What should be done to edit it?
a) With Explode command break into separate entities
b) Erase with Erase command
c) Delete the hexagon and draw again
d) Use array command
Explanation: Explode is the command which can break the multi-entity objects. Hexagon or any polygon should be broken into separate entities. Separated entities can be edited easily
4. To modify the properties of an existing entity, it is not necessary to select the item.
a) True
b) False
Explanation: To change any property of the existing entity, it is necessary to select the item first. In order to modify properties, select the object first. Then, click Home tab on the ribbon and click the triangle at the bottom of Properties panel.
5. Which of the following short-cut key is useful for modifying the 3-dimensional visualization properties?
a) CTRL + 1
b) CTRL + 5
c) CTRL + 3
d) CTRL + 4
Explanation: Three-dimensional visualization properties can be changed by modifying properties. CTRL + 1 is the key used for modifying properties. Shadow display and material properties can be changed in these options.
6. Elements of dimensioning are ___________
a) Extension line, Leader line, Arrowheads
b) Trim, Crop, Construction line
c) Polyline, Helix
d) Donut, Circle
Explanation: Elements of dimensioning consist of some important parts: Extension line, Leader line, Dimensional line, Pair of arrows, Dimensional values. Dimension line indicates the direction on which the dimension is to be measured. Extension line extends or elongates the line outside the object. Arrowhead is an important part of the dimension line, extension line & leader line.
7. ______ lines extend from the object towards outside.
a) Dimension
b) Extension
c) Leader
d) Arrowhead
Explanation: Extension line elongates the line outside to the object. Extension line indicates the extreme boundaries of the object where a dimension is to be measured. These lines are continuous and thin which are also used in dimensional line, hence the thickness of the line is the same for both the lines
8. An extension line should ________ any line.
a) cross
b) not cross
c) pass over to
d) pass below to
Explanation: Extension line should not cross with other lines i.e. Leader line or Dimensional line. When extension line crosses the leader line or dimension line or another extension line, they are not shown broken but extension line crosses the arrow, it has to be shown broken.
9. A leader line is drawn at an angle between _______ and not less than 30 degrees from horizontal.
a) 30 & 45 degree
b) 45 & 60 degree
c) 60 & 75 degree
d) 75 & 90 degree
Explanation: A leader line is drawn at an angle between 45 & 60 degrees but not less than 30 degrees from horizontal. A leader line should be drawn at an angle 45 degree from horizontal. This is the standard value of an angle. If more than one leader line is used the angle 45 degrees is used for better view
10. Leader line is pointed over an area; arrow is replaced by a dot about _____ diameter.
a) 1 mm
b) 2 mm
c) 3 mm
d) 1.5 mm
Explanation: Leader line is pointed over an area; arrow is replaced by a dot about 1.5 mm diameter. A leader line is used to indicate the dimension of a circular object, notes, part numbers etc. Leader line is just inclined thin line followed by horizontal line on which the note is to be written opposite side of line.
