Editing a Polyline

?

Opens the additional options to select objects.

Multiple

Selection of several objects mode.

The option initiates the following prompt in the command line:

Select objects [?/End]:

Option:

End                 – Ends the selection of objects объектов.

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/] <N>

Options:

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/] <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.
