Описание

Этот инструмент работает как инструмент Линия, но создаёт непрерывные отрезки линий и дуг, соединённых вершинами. При запуске инструмента указатель мыши меняется на белый крест с красным значком полилинии. Координаты указателя отображаются рядом с ним синим цветом в режиме реального времени.

Полилиния начинается с отрезка, продолжается дугой по касательной, перпендикулярной дугой и заканчивается касательной линией.

Применение

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.
