So far we have learned four drawing commands: line, arc, circle, and polyline.

These alone can help you accomplish only 20% of your drawing.

Also, if you think that each and every line (or arc, or circle) should be drawn by you, you are wrong!

In this chapter, we will discuss six commands:

• The Offset command, which creates parallel copies of your original objects.

• The Fillet command, which allows you to close unclosed shapes either by extending the two ends to an intersecting point, or by an arc.

• The Chamfer command, which is exactly the same as the Fillet command, except it will create a slanting edge.

• The Trim command, which allows some objects to act as cutting edges for other objects to be trimmed.

• The Extend command, which allows you to extend objects to a boundary.

• The Lengthen command, which allows you to extend or trim length from an existing line.

The Offset command will create a new object parallel to the selected object.

The new object (by default) will have the same properties of the original object, and will reside in the same layer.

There are two methods to offset:

• Using offset distance.

• Using a through point.

Make sure you on the Home tab on the Ribbon and using the Modify panel, click the Offset button. The following prompt will appear:
