AutoCAD: Offsetting options

The offset command has more options than you think.The Command "Offset" has more options than we generally use. I used to only use the "Through" option when I needed to offset a line or polyline to match with another one and I didn't know the distance.
Recently a clleague of mine asked me if I knew how to offset a line to both sides and erase the source line. So I went and check more carefully what the Offset Comand allows us to do.
When you type offset you will get the following response from AutoCAD:
  • "Specify offset distance or [Through/Erase/Layer] :"
Let's go from left to right. I already said what "through" will do. It will offset to the point we click on the screen instead of setting a distance.
Erase: this will give us the option to decide if we want to erase the source object or not. Remember that this option remains the way you used it last time so if you type yes on erase, any time you use the offset command again it will erase the original object unless you chose again not to erase.
Layer: this will allow us to choose between keeping the offset object in the source layer *the layer the original object is on) or place the new offset object in the current layer.

But this is not all. Once we chose the options we wanted and click on the object to be offset we will get the following prompt:
Specify through point or [Exit/Multiple/Undo] :
It is good to know what "Multiple" would do. It will allow us to ofset the object multiple times by just keep clicking on the side we want it to go.

So this is how I solved the question about offsetting to both sides an erasing the source object. Let's say she wanted to ofsset a line 1o units to both sides and erase the riginal object. The process would be the following.
o (for offset) --> 10 (we set the offset distance) --> e (call the erase options) --> Y (yes to Erasing source object) --> Click the line -->M (we want multiple offsets) --> one click to each side of the line --> Enter (end the command so the original line is erased)
It might seem a complicated process but it is actually not. Combining this with the layer options really brings the Offset command to a much powerful level that most of people might not know it is capable of.
