PLine

Works with Bricscad (Windows) Classic, Pro and Platinum, Bricscad (Linux) Classic and Pro

Draws polyline lines, arcs, and splines (short for "polyline"). A polyline is a multi-segment entity that can contain lines, arcs, and have width.

Accessing the Command

command bar: pline

aliases: pl, polyline

menu bar: Insert | Polyline

toolbar: Draw 2D |

: pline

Prompts you in the command bar:

Start of polyline:

Arc/Distance/Halfwidth/Width/<Next point>: (Pick a point, or enter an option.)

Arc/Distance/Follow/Halfwidth/Width/Undo/<Next point>: (Pick a point, enter an option, or press Enter to exit.)

Arc/Close/Distance/Follow/Halfwidth/Width/Undo/<Next point>: (Pick a point, enter an option, or press Enter to exit.)

Command Options

Option	Description
Start of polyline	Specifies the start point of the polyline's first segment. Enter x,y,z coordinates, or pick a point in the drawing.
Next point	Specifies the next point (endpoint for the current segment). Each next-point becomes a vertex in the polyline.
Arc	Switches to arc-drawing mode; draws "polyarcs." See Arc command.
Close	Closes the polyline. Bricscad automatically draws a segment from the current next-point to the starting point.
Distance	Specifies the length and angle of the next segment; prompts you: Distance for segment - specify the length of the segment. Angle of segment - specify the angle of the segment. Distances are measured from the last vertex. Angles are measured counterclockwise from the positive x-axis.
Follow	Draws the next segment at the same angle; move the mouse to indicate the length.
Halfwidth	Specifies the halfwidth for the current segment, as well as all segments that follow -- until you change the width or halfwidth. You can specify different starting and ending halfwidths, which creates tapered segments; prompts you: Starting half-width - specify the width at the start end of the segment; enter a value, or pick two points in the drawing. Ending half-width - specify the width at the start end of the segment; enter a value, or pick two points in the drawing.
Width	Specifies the width for the current segment, as well as all segments that follow -- until you change the width or halfwidth. You can specify different starting and ending widths, which creates tapered segments; prompts you: Starting width - specify the width at the start end of the segment; enter a value, or pick two points in the drawing. Ending width - specify the width at the start end of the segment; enter a value, or pick two points in the drawing. When you specify 0 as the width, the polyline is drawn like a line.
Undo	Undoes (undraws) the last segment.

Grips Editing

Polylines can be edited directly through grips:

Select the polyline. Notice that it has two or more grips:
- Line segments have one grip at each end of the segment.
- Arc segments have a grip at each end, plus one at the midpoint.
Drag a grip to stretch the polyline segment.

Splined polylines have a grip at each control point, which can be stretched:

Curve-fit polylines have many grips, which can be stretched:
