1.The following objects can be selected as cross sections: 2D polyline, spline, arc, elliptical arc, and line.
2.The following objects can be selected as path: 3D polyline, spline and line.

Command Prompts:

Select cross sections in lofting order or [MOde]:

Those cross sections determine the shape of 3D solids or surfaces and there must be at least two cross sections.

Lofting profile can be open or closed, planar or non-planar, and can also be edge of sub objects.

Select cross sections in lofting order

Specifies open or closed cross sections in lofting order.

Guides:
Specify loft guides to control solid or surface shape. Users can specify control points to match corresponding cross sections.
Note: The guide surface must intersect with each cross section. The guide surface starts from the first cross section. The guide surface ends at the last cross section. Users can select a few guides for lofting surfaces or solids and press ENTER to finish.
