At a Glance
Draws a path made of connected straight line segments (and, optionally, arcs) by clicking a series of points in the drawing.
A Polyline can combine Line and Arc segments in the same path.
Parameters
| Parameter | Description |
|---|---|
| Segment type (Line / Arc) | Chooses whether the next segment placed is a straight line or a curved arc. |
| Point (coordinates) | Lets you type an exact coordinate for the next point instead of clicking it in the drawing. |
| Apply / Close | Finishes the path (Apply) or exits the tool (Close). |
Overview
Draws a path made of connected straight line segments (and, optionally, arcs) by clicking a series of points in the drawing.
Using Polyline
- Click to place the first point of the path.
- Click to place each following point — a straight segment connects it to the previous point (Shift constrains the segment to a standard angle). Switching to arc mode instead curves the segment to the next clicked point.
- Repeat to keep adding segments.
- Click back on the starting point to close the path into a loop, or right-click / press Enter to end the path where it is left open.
Line and Arc Segments
Use the Segment Type control to choose whether the next segment is a straight line or an arc. The type can be changed as the polyline is being built, allowing a single path to contain both straight and curved sections.
Hold Shift while placing a line segment to constrain it to a standard angle.
Click the first point again to close the polyline, or right-click / press Enter to finish it as an open path.
Result
A path made of one or more connected straight and/or curved segments, left open where the drawing ended or closed into a loop if clicked back to its starting point.
