AutoCAD Drawing insulation

Introduction

There are two main methods for quickly drawing isolation in AutoCAD.

The first and most straight forward way would be to drawing the isolation with the aid of polar.

Because isolation is drawn at an angle of 30 degrees we need to change the polar settings. So right-click on polar -> settings:

Now change te incremental angle to 30:

If you now draw in modelspace, the polar snaps to an angle of 30 degrees:

The polar method can be a bit time consuming for large drawings.

In some cases the use of a zigzag line type would be more suited:

For example: let's say that we want to draw isolation in this 'L' shape:

First draw a line through the center of the shape:

Now select the line and go to other in the linetype dropdown box:

If the ZIGZAG line type isn't present in the list, press load:

In the load window, select the ZIGZAG line type and pres 'Ok'

The ZIGZAG line type is now visible in the linetype mangager, so select it and press 'OK'

The line will now look something like this:
