# PLINE Command [GstarCAD 2027](Help%20System/GSTARCAD/2027/Index.md) → [Commands](Help%20System/GSTARCAD/2027/Commands/(Commands).md) → [P](Help%20System/GSTARCAD/2027/Commands/P/(P).md) ## Function Description: This command is used to create a 2D polyline. The 2D polyline is a single object composed by line and arc segments. ## Command Access: > **Icon:**  > **Menu:** Draw > Polyline > **Ribbon:** Home > Draw > Polyline > **Toolbar:** Draw > Polyline > **Command:** PLINE > **Alias:** PL ## Command Prompts: ``` Specify start point: Current line-width is 0.0000 Specify next point or [Arc/Halfwidth/Length/Undo/Width/aNgle]: ```  ## **Specify start point** Sets the starting point for the polyline. ## **Next point** Draws a line, specifies a second point. ## **Arc** Adds arcs to the polyline. - **Specify endpoint of arc:** Specify the endpoint of arc, it will display last prompt. - **Angle:** Specify the arc angle from the start point. Entering a positive angle, the arc will be created in anticlockwise direction; entering a negative angle, the arc will be created in clockwise direction. - **Specify endpoint of arc:** Specify the endpoint of arc.   - **CEnter:** Specify the center of arc.  - **Radius:** Specify the radius of arc.  - **CEnter:** Specify center of arc. - **Specify endpoint of arc:** Specify the endpoint of arc. - **Angle:** Specify the arc angle from the start point. - **Length:** Specify the chord length of specified arc. If the last object is an arc, it will create a new arc tangent with last arc.  - **Direction:** Specify the start direction of arc.  - **Halfwidth:** Specify the width from the segment center of polyline to its edge.  The halfwidth of start point will be default halfwidth of endpoint. The halfwidth of endpoint will become the sub-sequence default halfwidth for all segments until changed. The start point and the endpoint of wide lines lie in its center.Typically, it will automatically chamfer crossing point of adjacent segments. However, if arcs are created with sharp angle or by dash dot line or without tangential, they will not be chamfered.- **Line:** Exit "Arc" option and return to the PLINE command prompt. - **Radius:** Specify radius of arc. - **Second pt:** Specify the second point and endpoint for "3P" (create arc by 3 points).  - **Undo:** Remove the recent arc added to polyline. - **Width:** Specify width of next arc. The width of start point will be default width of endpoint. The width of endpoint will become the subsequent default width for all segments until changed. The start point and the endpoint of wide lines lie in its center. Typically, it will automatically chamfer crossing point of adjacent segments. However, if arcs are created with sharp angle or by dash dot line or without tangential, they will not be chamfered. ## **Close** Creates lines from the last point to the start point and forms a closed polyline. Users should select at least two points to create a polyline by this option.  ## **Halfwidth** Specifies the width from the segment center of the polyline to one of its edge. The halfwidth of start point will be default halfwidth of the endpoint. The halfwidth of the endpoint becomes the subsequent default halfwidth for all segments until changed. The start point and the endpoint of wide lines lie in its center. Typically, it automatically chamfers crossing point of adjacent segments. However, if arcs are created with sharp angle or by dash dot line or without tangential, they will not be chamfered. ## **Length** Creates a line in a specified length with the same angle of the last line. If the last line is an arc, the new created line will be tangent to it. ## **Undo** Removes the recent line added to the polyline. ## **Width** Specifies the width of the next line. The width of the start point is the default width of the endpoint. The width of the endpoint becomes the subsequent default width for all segments until changed. The start point and the endpoint of wide lines lie in its center. Typically, it automatically chamfers crossing point of adjacent segments. However, if arcs are created with sharp angle or by dash dot line or without tangential, they will not be chamfered. ## Angle Specifies the angle of the next line. --- **Related References：** - [Commands about Curved Objects (GstarCAD 2026)](../../../2026/Commands/00%20Command%20Groups/Commands%20about%20Curved%20Objects.md) - [Commands about Linear Geometric Objects (GstarCAD 2026)](../../../2026/Commands/00%20Command%20Groups/Commands%20about%20Linear%20Geometric%20Objects.md) **Related Tasks：** - [To Draw Polylines (GstarCAD 2026)](../../../2026/Commands/01%20Procedures/To%20Draw%20Polylines.md) - [To Modify Polylines (GstarCAD 2026)](../../../2026/Commands/01%20Procedures/To%20Modify%20Polylines.md) --- [Original help](https://www.gstarcad.net/help/GstarCAD_2027_en-US/detail/commandReferences_P/PLINE.html) · © Gstarsoft Co., Ltd.
