2D Polyline

The 2D Polyline command (and its Sketch variant when the Sketch option is enabled) permits you to draw a multi-sided polyline with each vertex sharing an elevation value of zero (Z=0).

Options

  1. Pick point or point ID Indicate the starting location for the polyline based on an entity snap or by specifying an existing point ID (number). Prompting switches to:
  2. -Arc/Close/Undo/+/-/Len/<End>
    • Arc: Starts an arc segment.

      After starting an arc, the command line will change to:

      CEn/Len/Sec/<Rad>

      • CEn: Allows you to specify the center point (or radius point) for the arc. After picking the center point, you must specify the arc end point and then the arc direction.
      • LEn: Allows you to specify the arc length. First you pick the arc end point and then you can enter the arc length. The minimum arc length is given to you.
      • SEc: Allows you to specify the second point and end point to define the arc.
      • RAd: Allows you to specify a radius length. First you pick the arc end point and then you can enter the radius length. The minimum radius length is given to you.
    • Close: Closes the polyline.

      Note: You must have at least two polyline segments drawn before you can close

    • Undo: Removes the last segment drawn.

      Note: You can Undo again and remove multiple segments.

    • +: Perpendicular distance to the right.
    • -: Perpendicular distance to the left.
    • Len: Specify an optional new direction and distance.

      The command line will change to:

      aZi/Brg/Ang/L/R/toPoint/<Len>

      • aZi: Specify a desired azimuth.
      • Brg: Specify a desired bearing.
      • Ang: Specify a desired angle (functionally equivalent to azimuth).
      • L: Alters the current direction by 90° to the left (ccw).
      • R: Alters the current direction by 90° to the right (cw).
      • toPoint: Sets the current direction to the specified point.
      • Len: Indicate the length (distance) to travel.
    • End: Terminates the polyline and ends the command.

Note: You can also draw by point number and even use ranges, as in 3-10,2,20-15 which would draw from 3-10 sequentially, then point 2, then 20-15 sequentially.

Note: During the polyline creation process, you can access other common controls; most notably the various Map Screen View Controls and Entity Snaps.

Note: Refer to the Command Options discussion for additional information.
