Descriere
Subtractive Loft creează un solid substractiv în Corpul activ făcând o tranziție între două sau mai multe schițe (denumite și secțiuni transversale). Forma sa este scăzută din solidul existent.
Cum se folosește
- Press the Subtractive loft button.
- In the Select feature dialog, select a sketch to be used as first cross-section and click OK.
- Alternatively, a single sketch can be selected prior to pressing the Subtractive loft button.
- In the Loft parameters, press the Add Section button.
- Select a sketch in the 3D view. Repeat to select more sketches.
- Set options if needed and click OK.
Opţiuni
- Ruled surface: makes straight transitions between cross-sections. Dos 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.
- Press the Remove Section button to remove a sketch, by selecting it in the 3D view.
Proprietăți
- DateLabel: name given to the operation, this name can be changed at convenience.
- DateSections: lists the sections used.
- DateRuled: see Options.
- DateClosed: see Options.
- DateMidplane: N/A
- DateReversed: N/A
- DateRefine: true or false. If set to true, cleans the solid from residual edges left by features. See Part RefineShape for more details.
Limite
- 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.
