OFFSET
Because the polyline is treated as a single entity, when you click one point on the polyline, you are able to offset the entire outline of the conference room at once. If the outline of the room had been drawn with the LINE command, using the OFFSET command would offset each line segment individually, and the corners would not meet.
Step 5. Use the OFFSET command to draw the outside line (showing depth) of the conference room walls (Figure 3-4), as described next:

Prompt |
Response |
Type a command: Specify offset distance or [Through Erase Layer] <Through>: Select object to offset or [Exit Undo] <Exit>: Specify point on side to offset or [Exit Multiple Undo] <Exit>: Select object to offset or [Exit Undo] <Exit>: |
Offset (or type O <Enter>) Type 5 <Enter> Click anyplace on the polyline P1→ (outside the rectangle, Figure 3-4) <Enter> |
The four options in the Offset prompt are offset distance, Through, Erase, and Layer. To complete the conference room wall, 5″ was set as the offset distance. To use any of the other options, type and enter the capital letter shown for the option in the command line or press <Enter> to start the <Through> default option.
Through
When you start the Through option and select the object to be offset, AutoCAD prompts: Specify through point or [Exit Multiple Undo] <Exit>:. You respond by clicking a point on the drawing through which you want the object to be offset.
Erase
When you start the Erase option, AutoCAD prompts: Erase source object after offsetting? [Yes No] <No>:. You can then respond with Yes or No, and AutoCAD continues by asking you to specify the offset distance, object to offset, and point on side to offset.
Layer
When you start the Layer option, AutoCAD prompts: Enter layer option for offset objects [Current Source] <Source>:. You can then respond with the selection of current or source layer, and AutoCAD continues by asking you to specify the offset distance, object to offset, and point on side to offset.
