Описание

Субтрактивный профиль создает субтрактивное твердое тело в активном теле путем перехода между двумя или более эскизами (также называемыми поперечными сечениями). После чего данная форма вычитается из существующего твердого тела.

Применение

Применение через диалог

  1. Press the PartDesign SubtractiveLoft.svg Subtractive loft button.
  2. In the Select feature dialog, select a sketch to be used as base profile object and click OK.
    • Alternatively, a single sketch can be selected prior to pressing the subtractive loft button.
  3. In the Loft parameters, press the Add Section button.
  4. Select the next sketch in the 3D view. Repeat to select more sketches in the order you want them to be lofted through. (You can change the section order any time later in the loft dialog by dragging sections in the list to the desired position.introduced in version 0.19)
  5. Set options if needed and click OK.

Применение в текущем Виде, напрямую

introduced in version 0.19

  1. Select several sketches. It is hereby important in what order you select them:
    • The sketch selected at first will become the base profile object in the next step
    • The sketches selected after the first one will become the loft sections. Also here the selection order is important: The sketch selected as second will become the first loft section, the one selected as third becomes the second section and so on. (You can change the section order any time later in the loft dialog by dragging sections in the list to the desired position.introduced in version 0.19)
  2. Press the PartDesign SubtractiveLoft.svg Subtractive loft button.
  3. Set options if needed and click OK.

Опции

  • Ruled surface: makes straight transitions between cross-sections. Does not apply to a loft with two cross-sections. If not checked, transitions will be smooth.
  • Closed: makes a transition from the last cross-section to the first, creating a loop.

Свойства

  • ДанныеLabel: name given to the operation, this name can be changed at convenience.
  • ДанныеSections: lists the sections used.
  • ДанныеRuled: see Options.
  • ДанныеClosed: see Options.
  • ДанныеMidplane: N/A
  • ДанныеReversed: N/A
  • ДанныеRefine: true or false. If set to true, cleans the solid from residual edges left by features. See Part RefineShape for more details.

Ограничения

  • Sketches must form closed profiles.
  • It is not possible to loft to a vertex.
  • A cross-section cannot lie on the same plane as the one immediately preceding it.
  • To better control the shape of the loft, it is recommended that all the cross-sections have the same number of segments. For example, for a loft between a rectangle and a circle, the circle may be broken down into 4 connected arcs.
