5. What is the meaning of the following symbol?
a) The bulb is on
b) The layer is visible
c) The layer is not visible
d) The bulb is off
View Answer
Explanation: Given symbol is indicating that the layer is visible in the drawing. If the bulb is not glowing, the layer is not seen in AutoCAD drawing. Therefore, it is the most important property of the layer on which the layer is shown in the drawing.
6. What is the meaning of following symbol?
a) The layer is visible
b) The layer is not visible
c) The layer has extra brightness
d) One or more layers may cause the drawing to be regenerated

7. Modifying a layer consist of ________________
a) Line weight and line type
b) Thawing
c) Freeze
d) Deleting a layer
View Answer
Explanation: Modifying a layer consists of the following points:
1 – Give line weight to the layer

8. The below given symbol is an indication of _______
a) The layer is not correct
b) Making a layer as a current layer
c) Creating a new layer
d) Deleting a layer
View Answer
