Up until now we learned only 4 drawing commands (namely; line, arc, circle, and polyline).

These alone can't help you accomplish merely 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 that will magically help us construct the most difficult drawings in no time.

These commands are:

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

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

• Chamfer command, exactly the same as Fillet except it will create a beveled edge (an edge with slope).

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

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

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

Offset 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.

To issue this command, use one of the following methods:

• From the dashboard and using 2D Draw panel, click the Offset button.

  

• From menus select Modify/Offset.

• Type offset (or o) in the Command window.

The following prompt will appear:
