Loft

1. Switch the ribbon to Solid, if necessary, and in the Extrude drop-down list, click Loft.
2. In the graphics area, select the sketch regions or model faces. Select multiple regions in their order. You cannot select the first and last region, and then a middle region.
3. Optionally, select the centerline path that passes through each profile. The path can have multiple, tangent entities. Select each path entity.
   NoteYou can select the centerline path entities at any time.
4. In the command ribbon, click Closed to return to the first region in the loft. To close the loft, it is required that it extends more than 180 degrees.
5. Select the Boolean Option:
   1. Join Adds material.
   2. Cut Removes material.
   3. Intersect Removes all material from the solid that does not overlap the new feature.
   4. New Component Creates a child component in the active component.

Use profiles that are open or closed. You can use a centerline path to control the curvature, or you can change the curvature at a profile. It is not required that the centerline path connects the profile centers, but it is required that it intersects the profiles.

You can create the loft with natural curvature, with a centerline path, or with transition curvature changes at each profile.

This loft uses the natural curvature.

This loft uses a centerline path.

This loft uses directional control at the last profile.

1. Switch the ribbon to Surface, if necessary. In the Extrude drop-down list, select Loft.
2. In the graphics area, select the sketch profiles and faces. You cannot select both open and closed profiles. Select the regions in order. You cannot select the first and last region, and then a middle region.
3. Optionally, change the transition curvature for the entire loft, set the transition curvature as you select each region, or select the centerline path.
   1. To change the transition curvature for the entire loft, in the edit box, enter a value between 0.0 and 1.0. In this image, the transition curvature is set to 0.2
      
   2. To change the transition curvature at a profile, on the command glyph, select DirControl (Directional Control). Use the manipulators to change the curvature.
      
      NoteIf you select DirControl for a profile, the loft transition curvature is reset to 0.
   3. Click the Centerline button, and select the path, which can have multiple, tangent entities. Chaining for the path is turned on by default. Turn chaining off to select the path entities manually.
4. In the command ribbon, click Closed to return to the first region in the loft. To close the loft, it is required that it extends more than 180 degrees.
5. Select the Creation Option:
   1. New Surface Creates the surface in the active component.
   2. New Component Creates a child component for the surface under the active component.
