## Descrizione

Questo strumento funziona come lo strumento Linea di Schizzo, ma crea una successione di segmenti e di archi collegati ai loro estremi. Le linee e gli archi si alternano con il tasto M.

Quando si avvia lo strumento, il puntatore del mouse assume la forma di croce bianca accompagnata dall'icona rossa di polilinea. Accanto al puntatore sono visualizzate, in blu, le coordinate della sua posizione, aggiornate in tempo reale.

La polilinea inizia con una linea, continua con un arco tangente, poi un arco perpendicolare quindi una linea tangente

## Utilizzo

1. There are several ways to invoke the tool:
• Press the 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.
