Loft with Guide Curve and Non-Planar Profile

You can create a guide curve loft by using two or more profiles and one or more guide curves to connect the profiles. The profiles can be either planar or non-planar. The guide curves help you control the intermediate profiles that are generated.

1. Use a split line to create a non-planar profile on a model face.
2. Sketch one or more guide curves.
3. Add a Pierce relation between the guide curves and an edge or vertex on the non-planar face.
4. Sketch the remaining profiles needed to create the loft.
5. Add relations between the profiles and guide curves:
   • Pierce relations between the guide curves and vertices, user-defined sketch points, or both, on the profiles.
   • Coincident relations between vertices, user-defined sketch points, or both, of the guide curves and the profiles.

6. Click one of the following:
   • Lofted Boss/Base (Features toolbar) or Insert > Boss/Base > Loft
   • Lofted Cut (Features toolbar) or Insert > Cut > Loft
   • Lofted Surface (Surfaces toolbar) or Insert > Surface > Loft
7. In the PropertyManager:
   1. Select the profiles to loft in the graphics area for Profiles .
      To select the profile sketch on the non-planar face, you must use the Select Group tool in the SelectionManager to select the individual profile sketch edges.

   2. Set the PropertyManager options.
