Creates a 2D polyline, a single object that is composed of line and arc segments.
Summary
A 2D polyline is a connected sequence of segments created as a single planar object. You can create straight line segments, arc segments, or a combination of the two.
The PLINEGEN system variable controls the linetype pattern display around and the smoothness of the vertices of a 2D polyline. Setting PLINEGEN to 1 generates new polylines in a continuous pattern around the vertices of the completed polyline. Setting PLINEGEN to 0 starts and ends the polyline with a dash at each vertex. PLINEGEN does not apply to polylines with tapered segments.
List of Prompts
The following prompts are displayed.
Sets the starting point for the polyline.
- If you specify a second point, you draw line segments.
- If you enter a (for Arc), you draw arc segments.
The following prompts are displayed when you draw arc segments.
- Angle
- Center
-
Specifies an arc segment based on its center point.
NoteFor the Center option of the PLINE command, enter ce; for the Center object snap, enter cen or center.- Center point of arc. Specifies the center point of the polyline arc.
- Endpoint of arc. Specifies the endpoint and draws the arc segment.
- Angle. Specifies the included angle of the arc segment from the start point.
- Length. Specifies the chord length (the distance from endpoint to endpoint of the arc segment. If the previous segment is an arc, the new arc segment is drawn tangent to the previous arc segment.
- Close
- Direction
-
Specifies the tangent for the arc segment.
- Tangent direction from the start point of the arc. Specifies a point that establishes a tangency of the curve to the start point. The arc curves away from the vector between the start point and the tangent point.
- Endpoint of the arc. Specifies the endpoint of the arc segment.
- Halfwidth
-
Specifies the width from the center of a wide polyline segment to one of its edges.
The starting half-width becomes the default ending half-width. The ending half-width becomes the uniform half-width for all subsequent segments until you change the half-width again. The starting and ending points of wide line segments are at the center of the line. Typically, the intersections of adjacent wide polyline segments are beveled. No beveling is performed for nontangent arc segments or very acute angles or when a dot-dash linetype is used.
- Starting half-width. Specifies the width and the start point of the segment.
- Ending half-width. Specifies the width at the endpoint.
- Line
- Radius
- Second pt
- Undo
- Width
-
Specifies the width of the next arc segment.
The starting width becomes the default ending width. The ending width becomes the uniform width for all subsequent segments until you change the width again. The starting and ending points of wide line segments are at the center of the line.
Typically, the intersections of adjacent wide polyline segments are beveled. No beveling is performed for nontangent arc segments, very acute angles, or when a dot-dash linetype is used.
- Starting width.
- Ending width.
The following prompts are displayed when you are drawing straight polyline segments.
- Next point
- Arc
- Close
- Halfwidth
-
Specifies the width from the center of a wide polyline line segment to one of its edges.
The starting half-width becomes the default ending half-width. The ending half-width becomes the uniform half-width for all subsequent segments until you change the half-width again. The starting and ending points of wide line segments are at the center of the line.
Typically, the intersections of adjacent wide polyline segments are beveled. No beveling is performed for nontangent arc segments or very acute angles or when a dot-dash linetype is used.
- Starting half-width. Specifies the width and the start point of the segment.
- Ending half-width. Specifies the width at the endpoint.
- Length
- Undo
- Width
-
Specifies the starting and ending width of the next line segment.
The starting width becomes the default ending width. The ending width becomes the uniform width for all subsequent segments until you change the width again. The starting and ending points of wide line segments are at the center of the line.
Typically, the intersections of adjacent wide polyline segments are beveled. No beveling is performed for nontangent arc segments or very acute angles or when a dot-dash linetype is used.
