Description

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.

introduced in version 0.17

PartDesign AddLoft example.png

On the left: cross-sections (A), (B) and (C); created Additive loft on the right.

How to use

  1. Press the PartDesign AdditiveLoft.png Additive 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 Additive 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.

Options

  • 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.

Properties

  • DataLabel: name given to the operation, this name can be changed at convenience.
  • DataSections: lists the sections used.
  • DataRuled: see Options.
  • DataClosed: see Options.
  • DataMidplane:
  • DataReversed:
  • DataRefine: true or false. If set to true, cleans the solid from residual edges left by features. See Part RefineShape for more details.

Limitations

  • 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.
