What is the minimum allowable numbers of layers in a drawing?(a) 0(b) 1(c) 2(d) 10This question was posed to me during an interview for a job.This interesting question is from Computer Aided Drafting in portion Nomography, Computer Aided Drafting & Procedure of Estimating of Civil Engineering Drawing

Answer»

Right choice is (b) 1

The EXPLANATION: The following are the most commonly used layer settings in the Layer Properties Manager. You click the icon to turn the setting on and off.

• Turn off layers. You turn off layers to REDUCE the visual complexity of your drawing while you work.

• Freeze layers. You freeze layers that you do not need to access for a while. Freezing layers is similar to turning them off, but improves performance in very large drawings.

• Lock layers. You lock layers when you want to prevent accidental changes to the objects on those layers. Also, the objects on locked layers appear FADED, which helps reduce the visual complexity of your drawing, but still lets you see the objects faintly.

• Set default properties. You set the default properties for each layer, including color, linetype, LINE weight, and transparency. New objects that you create will use these properties UNLESS you override them. Overriding layer properties is explained later in this topic.
