Tanım

Subtractive Loft creates a subtractive solid in the active Body by making a transition between two or more sketches (also referred to as cross-sections). Its shape is then subtracted from the existing solid.

Usage

Dialog-based workflow

  1. Press the Subtractive loft button.
  2. In the Select feature dialog, select a sketch to be used as base profile object and click OK.
    • Alternatively, either a single sketch or the face of a 3D object (introduced in version 0.20) 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.

Selection-based workflow

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)
    • The first or last selection can also be a face of a 3D object (introduced in version 0.20)
  2. Press the Subtractive loft button.
  3. Set options if needed and click OK.

Options

  • 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.

Properties

  • VeriLabel: name given to the operation, this name can be changed at convenience.
  • VeriSections: lists the sections used.
  • VeriRuled: see Options.
  • VeriClosed: see Options.
  • VeriMidplane: N/A
  • VeriReversed: N/A
  • VeriRefine: true or false. If set to true, cleans the solid from residual edges left by features. See Part RefineShape for more details.

Notes

  • To better control the shape of the loft, it is recommended that all cross-sections have the same number of segments. For example, for a loft between a rectangle and a circle, the circle should be broken down into 4 connected arcs.
  • You can loft from or toward a single vertex from a sketch or the body. introduced in version 0.20
  • Vertices can in most cases only be the start or end of a loft.
  • A cross-section cannot lie on the same plane as the one immediately preceding it.
  • 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.
  • It is not possible to loft disjoint or crossing loops.
