Use the EditPolyLine command to edit PolyLines, PolyLine vertices, and 3D PolygonMeshes by:
- Opening a closed PolyLine or closing an open PolyLine
- Joining a PolyLine with other drawing entities such as Lines, Arcs, or PolyLines
- Changing the width of the whole PolyLine
- Editing the control points (vertices) of individual PolyLine segment
You can perform many edits of one or more PolyLines with a single EditPolyLine command. If you revert PolyLine editing with a subsequent Undo command, all the working steps are reverted as a whole.
To edit PolyLines:
- Click Modify > Entity > PolyLine (or type EditPolyLine).
- In the graphics area, select a PolyLine, or specify the Multiple option to select a group of PolyLines and press Enter.
If a selected Line or Arc is not a PolyLine, you are given the option to convert it to one. Also use this method to turn a series of individual but connected Lines, Arcs, and PolyLines into a single PolyLine. In a single EditPolyLine command, you can first convert a Line or Arc into a PolyLine. Then use the Join option to add the other entities to the PolyLine.
- Specify an option:
- Close / Open: The option displays Close if the PolyLine is open and Open if the PolyLine is closed. The option Back is also available after a polyedit operation. Specify the Close option to join the start and end points of the PolyLine with a straight PolyLine segment. The width of this segment is the width of the end point of the last drawn PolyLine. Specify the Open option to delete the PolyLine segment between the start and end points.
- Decurve: Reverts a PolyLine curve created using Fit or Spline to its original vertices.
- Edit vertex: Lets you edit the marked vertex by using a vertex editing option. You can also use EntityGrips for some of the options, like Move. If you specified the Multiple option, you cannot use the Edit vertex option.
- Insert: Inserts a new vertex. Specify the new location.
- Move: Moves the current vertex. Specify the new position.
- Next: Proceeds to the next vertex and makes it the active one.
- Previous: Returns to the previous vertex and makes it the active one.
- Regen: Regenerates the PolyLine.
- Split: Divides the PolyLine into two parts, similar to the Split command.
- Straighten: Deletes vertices.
- Tangent: Specifies a tangent direction for the vertex when you specify the Fit option during PolyLine editing.
- Width: Specifies a starting and ending width for the PolyLine segments that start at the active vertex. To see the effect, use the Regen option.
- Exit: Exits the Edit vertex mode.
- Fit: Turns the PolyLine into a smooth curve consisting of arcs joining each pair of vertices, thus resulting in an arc-fit PolyLine. Unlike the Spline option, the curve passes through all vertices of the PolyLine.
- Join: Merges Lines, Arcs, and other PolyLines with the selected PolyLine. Select the drawing entity to join. The PolyLine to edit and the entity to join must meet exactly in one end point.
- Linegen (line generation): Indicates for PolyLines with a noncontinuous LineStyle whether to use a continuous or dashed LineStyle around the vertices. Specify the No option to place breaks between dashes in LineStyles so they are positioned properly at corners. Specify the Yes option to set the LineStyle to a fluent pattern around the vertices of the PolyLine.
- Spline: Turns the PolyLine into a curve using the vertices as control points. Unlike the Fit option, the curve usually does not pass through the vertices. Note: Curves created with the Spline option are not true splines in the mathematical sense. To create genuine splines, use the Spline command.
- Undo: Reverses the most recent operation without exiting the command.
- Width: Specifies one width to make PolyLines uniform for all segments, including those with different start and end widths. Specify the width by typing a value or using the pointer.
- Exit: Exits the EditPolyLine command.
