Creates a three-dimensional solid or surface between two or more cross sections. Cross sections can be open or closed entities. Open cross sections create three-dimensional surfaces. Closed cross sections create three-dimensional solids or surfaces, depending on the specified mode.

Cross sections can be 2D polylines, lines, arcs, circles, ellipses, elliptical arcs, 2D splines, helixes, traces, edges of entities, faces of a solid or surface, points of the first or last cross section, regions, and 2D solids.

Guides can be 2D polylines with a single segment, 3D polylines, lines, arcs, elliptical arcs, 2D and 3D splines, and edges of entities.

Paths can be 2D and 3D polylines, lines, arcs, circles, ellipses, elliptical arcs, 2D and 3D splines, helixes, and edges of entities.

To create a lofted solid or surface

Select cross sections in lofting order or [POint/Join multiple edges/MOde]: Select the cross sections in the order you want to loft them. You must select at least two cross sections. When done, press Enter.

Enter an option [Guides/Path/Cross sections only/Settings] <Cross sections only>: To create the three-dimensional entity between the cross sections without using guides or paths, choose Cross sections only. To create the three-dimensional entity using guides, choose Guides. To create the three-dimensional entity along a path, choose Path. To specify settings for the three-dimensional entity, choose Settings to display the Loft Settings dialog box.

To create a lofted solid or surface using guides

Choose Guides.

Select guide curves or [Join multiple edges]: Select guide curves to shape the loft; guide curves must intersect each cross section and begin and end at the first and last cross section. Guide curves determine the shape of the resulting three-dimensional entity.

To combine multiple edges into a cross section, choose Join multiple edges, then select the edges.

To create a lofted solid or surface using a path

Choose Path.

Select a single path: Select the path for the lofted entity. The path must intersect the solid or surface on all planes.

To specify a start or end point for a taper while lofting

Select cross sections in lofting order or [POint/Join multiple edges/MOde]: Choose POint.

Pick interior point to select closed boundaries: Select the start or end point of the loft entity.

Continue creating the loft entity using the prompts described above.

To join multiple edges to create a cross section while lofting

Select cross sections in lofting order or [POint/Join multiple edges/MOde]: Choose Join multiple edges.

Select edges that are to be joined into a single cross section: Select the edges, which must share start and end points, to be considered as a cross section. When done selecting edges, press Enter.

Continue creating the loft entity using the prompts described above.
