Описание
Additive Loft creates a solid in the active Body by making a transition between two or more sketches (also referred to as cross-sections). If the Body already contains features, the additive loft will be merged to them.
On the left: cross-sections (A), (B) and (C); created Additive loft on the right.
Применение
Dialog-based workflow
- Press the Additive loft button.
- 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 Additive loft button.
- In the Loft parameters, press the Add Section button.
- 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)
- Set options if needed and click OK.
Selection-based workflow
- 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)
- Press the Additive loft button.
- Set options if needed and click OK.
Опции
- Управление поверхностью: делает прямолинейные переходы между поперечными сечениями. Не оказывает никакого эффекта, в случае если профиль формируется только по двум поперечными сечениям. Если пункт не установлен, переходы между сечениями будут плавными.
- Замкнуть: выполняет переход от последнего поперечного сечения к первому, создавая замкнутую форму.
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.
- ДанныеRefine: true or false. If set to true, cleans the solid from residual edges left by features. See Part RefineShape for more details.
- ДанныеProfile: the see base profile object of the loft.
- ДанныеMidplane: non applicable.
- ДанныеReversed: non applicable.
- ДанныеUp To Face: non applicable.
- ДанныеAllow Multi Face: non applicable.
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.
- Loft will be created in the order that cross sections were added
- If the sketch has inner geometry, i.e. the loft is supposed to have holes, then the order in which the sketch geometry is created should be the same for all sections: either start all sections with the inner geometry or start them all with the outer. Otherwise an invalid loft can be created where inner and outer walls cross.
Known Issues
- Some failure modes will turn the part black
