TechDraw Workbench/ru

Введение

В чертеж могут быть добавлены такие элементы как: размеры, сечения 3D Вида, дополнительные заштрихованные области, надписи и примечания, чертежные знаки в формате SVG. Чертеж так же можно экспортировать в различные форматы, такие как DXF, SVG или PDF.

Если вашей основной целью является создание сложных 2D чертежей и файлов в формате DXF, и вам не нужно 3D-моделирование, возможно FreeCAD будет не самым лучшим выбором для вас. Вы можете использовать специальное программное обеспечение для построения технических чертежей, такое как LibreCAD или QCad.

Snapping

introduced in version 1.0: The TechDraw Workbench has a snapping feature. It can be used to automatically align views, section views and dimensions when positioning them by dragging with the mouse. With Snap View Alignment enabled (default) in the preferences, views will snap to alignment with other views when close enough (View Snapping Factor setting). Dimensions are also snapped to other parallel dimensions and the dimension text can be snapped to the middle of the dimension line. Snapping can be temporarily disabled by holding down the Alt key.
