Quickly set CAD multi-layer drawing select print and full black print

Today, the customer sent a drawing of the mail, the first look scared me, the original is a more complex general plan.

This complex CAD multi-layer drawing needs to be printed, and some layers do not need to be printed. Because you want to save costs, you need to print all black. I looked at its layer, a total of 118 layers, if you want to change the color of its layers, more time-consuming, by pondering, I found two good ways to share with you.

Method One

(i) lock unwanted layers

1, such as "grassland" do not need to look at the layer where it is,

1, open the Layer feature manager, the layer is locked, and set to "Do not print."
