PLine

Start of polyline

Specifies the start point of the polyline's first segment:

• Enter x,y,z coordinates
• Pick a point in the drawing

Last point

Starts the polyline at the last point picked in the drawing, which is useful for continuing from an existing polyline.

Next point

Specifies the next point (endpoint for the current segment); each next-point becomes a vertex in the polyline.

Arc

Switches to arc-drawing mode; draws arc segments; prompts you:

Set end of arc or [draw Lines/ Angle/ CEnter/ CLose/ Direction/ Halfwidth/ Radius/Second point/Width/Undo] - (pick a point or choose an option.)

• draw Lines - switches to line-drawing mode; draws line segments.

• Angle - sets the included angle of the arc segment; prompts you:
  Included angle for segment (+ for ccw, - for cw) - (enter an angle.)
  Set end of arc or [Center/Radius] - (pick point or choose an option.)

• CEnter - sets the center of the arc segment; prompts you:
  Center point - (pick a point.)
  Set end of arc or [Angle/Length of chord] - (pick a point or choose an option.)

• CLose - closes the arc and then returns to the previous prompt

• Direction - defines the direction of the tangent line in the start point of the arc; prompts you:
  Direction from start - (pick a point to define the direction of the tangent line.)
  End of arc - (pick a point.)

• Halfwidth - specifies the halfwidth of the arc, the distance from the centerline to the edge of the wide arc; prompts you:
  Starting half-width <0> - (enter a width for the start of the arc segment.)
  Ending half-width <175.96> - (enter a width for the end of the arc segment.)
• Radius - specifies the radius of the arc; prompts you:
  Radius of arc - (specify a radius.)
  Set end of arc or [included Angle] - (pick a point to end the arc.)

• Second point - prompts you to define the second point and endpoint of a 3-point arc; prompts you:
  Second point - (pick a point along the arc.)
  End of arc - (pick a point to determine the end of the arc.)

See the Arc command.

Close

Closes the polyline; the program automatically draws a segment from the current next-point to the starting point.

Distance

Specifies the length and angle of the next segment; prompts you:

1. Distance for segment - (specify the length of the segment.)

2. Angle of segment - (specify the angle of the segment.)

Distances are measured from the last vertex. Angles are measured counterclockwise from the positive x-axis.

Follow

Draws the next segment at the same angle; move the mouse to indicate the length.

Halfwidth

Specifies the halfwidth for the current segment, as well as all segments that follow -- until you change the width or halfwidth.

You can specify different starting and ending halfwidths, which creates tapered segments; prompts you:

1. Starting half-width - (specify the width at the start end of the segment; enter a value, or pick two points in the drawing.)

2. Ending half-width - (specify the width at the start end of the segment; enter a value, or pick two points in the drawing.)

Width

Specifies the width for the current segment, as well as all segments that follow -- until you change the width or halfwidth.

You can specify different starting and ending widths, which creates tapered segments; prompts you:

1. Starting width - (specify the width at the start end of the segment; enter a value, or pick two points in the drawing.)

2. Ending width - (specify the width at the start end of the segment; enter a value, or pick two points in the drawing.)

When you specify 0 as the width, the polyline is drawn to look like a line.

Undo

Undoes (undraws) the last segment.
