Loft option in Rapidform XOR

Loft creates a feature by making transitions between profiles.


How to use Loft command

Clickimage47_687 button on the toolbar, or clickInsert > Solid > Loft.


Select the Profiles to loft.


Click OK.image47_690


Profiles– Determines the profiles used to create a loft. Select SketchEdge, 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.


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

2. The profile should be planar except selecting Face.

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 Vertices applies 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.


d) Tangency to Face: Keep tangency to selected face.

e) Curvature to Face: Keep curvature to selected face.


  • 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.


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.
