LOFT command


The LOFT command is used to create 3D solids or surfaces by several cross sections.

Command Access:

Ribbon : 3D > Modeling > Extrude > Loft
Menu : Draw> Modeling > Loft
Command : LOFT

Command Prompts:

Select cross sections in lofting order: Enter an option [Guides/Path/Cross sections only] :

Function Description:

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

User could apply the LOFT command on the following objects or sub objects:
1.The following objects could be selected as cross sections: 2Dpolyline, spline, arc, elliptical arc, and line.
2.The following objects could be selected as path: 3Dpolyline, spline and line.
3.The following objects could be selected as guides: Spline and line. Users could set the DELOBJ system variable to delete cross sections, guides and path automatically.

Relative Glossary:

Select cross sections in lofting order:
Specify open or close cross sections in lofting order.
Guides:
Specify loft guides to control solid or surface shape. Users could 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 could select a few guides for lofting surfaces or solids and press ENTER to finish

Path: Specify loft path for solid or surface. The path must intersect with planes of cross sections.

autocad loft command cross section only

Cross sections only: Create loft by cross sections without guides or path.
