Lofting is a method that allows you to create complex
three-dimensional features that cannot be created by extruding, revolving, or
sweeping.
For example, you can use lofts to model an exhaust manifold that
would be difficult to create by other means due to varying cross-sections. You
can create solid, shell, or cut loft features in
Abaqus/CAE.
A loft feature transforms from a starting section shape and orientation to an
ending shape and orientation. You first create sections that define the shape
of the loft as it passes through an area in space. Then
Abaqus/CAE
can create the path between sections automatically, or you can define one or
more continuous paths connecting one point on each loft section to a
corresponding point on the next section. You can also choose from several
tangency options to control the shape of the loft as it leaves the starting
section or as it approaches the ending section. This section describes the
options available for defining the loft sections, loft paths, and loft
tangencies prior to creating a loft feature and explains
self-intersection.
