Loft option in Rapidform XOR

Loft creates a feature by making transitions between profiles.

Profiles – Determines the profiles used to create a loft. Select Edge, 2D Sketch, 2D Sketch Chain, 3D Sketch, 3D Sketch Chain, Region, Loop, Face to connect. Lofts are created based on the order of profile selection.

Note

1. The open loft solid needs 2 more profiles but the closed loft needs 3 more profiles.

2. Non-planar profile can be used for loft surface.

3. To make a composite profile from connected edges or curves, select edges or curves with the Shift button.

 

  • Constraints – Applies a constraint to control tangency to the start and end profiles. The following options are available:
  • Start Constraint– Constraints to start profiles.
a)None: No tangency constraint (zero curvature) is applied.

 

b)Direction Vector: Applies a tangency constraint based on a selected entity used as a direction vector. Select a Direction Vector, and then set the Draft angle and Start or End Tangent Length. Use Same Tangent Length To All Verticesapplies same tangency to all vertices of profile.

c)Normal to Profile: Applies a tangency constraint normal to the start or end profile. Set the Draft angle and Start or End Tangent Length.

  • End Constraint– Constraints to end profiles. The options are similar to start constraint.
  • Guide Curves – Guide curves to loft along that curve. Start Constraint options to the guide curve are similar to the profile start constraints.

<Without Guide Curve> <With Guide Curve>

  • Merge Tangent Faces– If this option is enabled, tangent faces will be merged.
  • Close Loft – If this option is enabled, Loft will be closed.
  • Result Operator:This option is available when there exist one more bodies.
    a) Cut: When the two solids make an intersection, the resultant solid is cut
    to keep only the intersected part.
    b) Merge: The resultant solid is merged with the first body.
