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 de solidul existent.

introduced in version 0.17

Cum se folosește

  1. Press the Subtractive loft button.
  2. 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.
  3. In the Loft parameters, press the Add Section button.
  4. Select a sketch in the 3D view. Repeat to select more sketches.
  5. 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.
