This tool works like the [[Sketcher CreateLine|Sketcher Line]] tool, but creates continuous line and arc segments connected by their vertices. When starting the tool, the mouse pointer changes to a white cross with a red polyline icon. The coordinates of the pointer are shown beside it in blue in real time.
The [[Image:Sketcher_CreatePolyline.svg|24px]] [[Sketcher_CreatePolyline|Sketcher CreatePolyline]] tool creates a series of line and arc segments connected by their endpoints. The tool has several modes.

# There are several ways to invoke the tool:
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:
#* Press the {{Button|[[Image:Sketcher_CreatePolyline.svg|16px]] [[Sketcher_CreatePolyline|Create polyline]]}} button.

#* Select the {{MenuCommand|Sketcher → Sketcher geometries → [[Image:Sketcher_CreatePolyline.svg|16px]] Create polyline}} option from the menu.

# Press the {{KEY|M}} key: the new segment is a line which is perpendicular to the previous segment.

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.

  1. 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.
  2. The cursor changes to a cross with the tool icon.
  3. 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).
  4. 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.
  5. 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.
  6. Pick the endpoint of the segment.
  7. Optionally repeat this to create more segments.
  8. 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.
  9. The polyline segments have been created and applicable constraints have been added.
  10. If the tool runs in continue mode:
    1. Optionally keep creating polylines.
    2. To finish, right-click or press Esc, or start another geometry or constraint creation tool.
