The polyline always starts with a straight line segment: click - move the mouse - click. Move the mouse again. After placing the first line segment, the Sketcher polyline tool has multiple modes that can be toggled with the {{KEY|M}} key. For example you can draw tangent or perpendicular arcs following a line or arc segment. Repeatedly pressing the {{KEY|M}} key toggles through these different modes: |

Description
The Sketcher CreatePolyline tool creates a series of line and arc segments connected by their endpoints. The tool has several modes.
Polyline started with a line, a tangent arc, a perpendicular arc then a tangent line.
Usage
See also: Drawing aids.
- There are several ways to invoke the tool:
- Press the Create polyline button.
- Select the Sketcher → Sketcher geometries → Create polyline option from the menu.
- Right-click in the 3D view and select the Create polyline option from the context menu.
- Use the keyboard shortcut: G then M.
- The cursor changes to a cross with the tool icon.
- The modes of the tool require a previous segment. Do one of the following:
- Pick two points to define a line segment.
- Pick the endpoint of an existing line or arc segment (Auto constraints must be enabled).
- Optionally press the M key one or more times to cycle through the modes for the next segment. The available modes are:
- Line perpendicular to the previous segment.
- Line tangential to the previous segment (this is the initial mode if the previous segment is an arc).
- Arc tangential to the previous segment.
- Arc perpendicular (left) to the previous segment.
- Arc perpendicular (right) to the previous segment.
- Line only connected to the previous segment.
- While in any of the arc modes, optionally hold down the Ctrl key to snap the arc to increments of 45° relative to the previous segment.
- Pick the endpoint of the segment.
- Optionally repeat this to create more segments.
- To finish the input do one of the following:
- Snap to the start point to create a closed polyline.
- Right-click or press Esc to create an open polyline.
- The polyline segments have been created and applicable constraints have been added.
- If the tool runs in continue mode:
- Optionally keep creating polylines.
- To finish, right-click or press Esc, or start another geometry or constraint creation tool.
