Editing a Polyline

Editing a Polyline
Ribbon: Home, Draw – Modify > Edit Polylines

Menu: Modify – Object> Polyline

Toolbar: Modify object –

Command line: PE, PEDIT

Double clicking on a polyline starts the editing mode.

Using the Polyline command you can edit polylines and also convert elementary objects, consisting of arcs and lines, into polylines.

Command options:

? Opens the additional options to select objects.

Multiple Selection of several objects mode.

Close Closes (draws a segment from start to end vertex) a polyline.

+Open + Opens a polyline (deletes a segment from start to end vertex).

Edit vertex Switches to the editing of vertexes mode (edited vertex is marked with “X” label). The option starts the following prompt in the command line: Enter a vertex editing option [Next/Previous/Break/Insert/Move/Regen/Straighten/ Tangent/Width/Exit/] Next – Goes to the next vertex. +Previous+- Goes to the previous vertex. +Break+- Breaks a polyline at the selected vertex. +Insert+- Adds a vertex in the specified place. +Move+- Changes the position of the selected vertex.+Regen+- Regenerates a polyline. +Straighten+- Changes a line segment to an arc segment. +Tangent+- Specifies the direction of the tangent in the selected vertex for further polyline fitting. +Width+- Specifies the first and second width of the segment, going after the selected vertex. +Exit+- Closes the editing of vertexes mode.

Join Joins segments, arcs and polylines into one object – polyline. The option starts the following prompt in the command line:

Select polyline or [?/End]:

Option:

End- Closes selection of objects.

Width Specifies a new width for all polylines.

Fit Fits the polyline with arcs between polyline vertexes.

Spline Transforms a polyline into a spline which is an approximation of the source polyline between the start and end vertexes and is very similar to the source polyline.

Decurve Returns a polyline to its original condition, cancels the results of the Fit or Spline commands.

Ltype gen Specifies a mode of the specified line type generation. The option starts the following prompt in the command line: Enter polyline linetype generator option [ON/OFF/] : If Off option is selected, generation of line type starts from dash and end dash in very vertex.

rEverse Changes the order of vertices to the opposite. The option is used to reverse the direction of objects that use linetypes with included text. For example, in accordance with the direction in which polyline was created, text for this linetype can be displayed inverted.

Undo Cancels the last action of polyline editing.

Command prompts when selecting a polyline:

Select polyline or [?/Multiple]: Select Multiple.
Select polyline or [?/Multiple]: Select objects.
Do you want to turn it into one? [Yes/No] : Press Enter or select No.

Enter an option [Close/Edit vertex/Join/Width/Fit/ Spline/Decurve/Ltype gen/Undo]: Select the required option. Press Enter to finish the command.

Command prompts to convert an object to a polyline:

Select polyline or [?/Multiple]: Select an object (line, arc, spline).

Object selected is not a polyline. Do you want to turn it into one? [Yes/No/]: Press ENTER or select Yes option. If you need to undo the selection, specify No.

Specify a tolerance <10>: When selecting a spline, enter the tolerance value to convert or press ENTER.

Enter an option [Close/Edit_vertex/Join/Width/Fit/Spline/Decurve/Ltype_gen/Reverse/Undo]: Select an option necessary for editing.

Upon completion of editing, press ENTER to end the command.

Command prompts when selecting multiple objects:

Select polyline or [?/Multiple]: Select the Multiple option.

Select objects [?/End]: Select objects.

Select objects [?/End]: Select the End option.

Convert Lines, Arcs and Splines to polylines? [yes/No] : Press ENTER or select Yes. If you need to undo the selection, specify No.

Enter an option [Close/Edit_vertex/Join/Width/Fit/Spline/Decurve/Ltype_gen/Reverse/Undo]: Select an option necessary for editing. Upon completion of editing, press ENTER to end the command.
