Modifying entities - Copying entities

Making parallel copies

You can use the offset feature to copy selected entities and align them parallel to the original entities at a specified distance. You can make parallel entities using arcs, circles, ellipses, elliptical arcs, lines, two-dimensional polylines, rays, and infinite lines.

Making parallel copies of curved entities creates larger or smaller curves, depending on which side of the original entity you place the copy. For example, placing a parallel copy of a circle outside the circle creates a larger concentric circle; positioning the copy inside the circle creates a smaller concentric circle.

To make a parallel copy by specifying the distance
  1. Do one of the following:
  2. Choose Modify > Offset.
  3. On the Modify toolbar, click the Offset tool (
    4. ).
  • Type offset and then press Enter.
  • Specify the distance by selecting two points or by entering a distance.
  • Select the entity to copy.
  • Specify on which side of the entity to place the parallel copy.
  • Select another entity to copy, or press Enter to complete the command.
 
 

 

 

To make a parallel copy, specify the distance between copies by entering a distance or selecting two points ( A and B ), select the entity to copy ( C ), and specify on which side to place the copy ( D ).
