Creates a 3D solid or surface by sweeping a 2D or 3D object or subobject along a path.
Summary
Creates a solid or surface by sweeping an open or closed, planar or non-planar curve (profile) along an open or closed path. Open curves create surfaces and closed curves create solids or surfaces, depending on the specified mode.
You can use the following objects and paths when creating a swept solid or surface:

Note Select face and edge subobjects by pressing Ctrl while you select them.
To automatically delete the original geometry used to create the object, use the DELOBJ system variable. For associative surfaces, the DELOBJ system variable is ignored and the originating geometry is not deleted.
List of Prompts
The following prompts are displayed.
-
Objects to Sweep
-
Specifies an object to use as the sweep profile.
-
Sweep Path
-
Specifies the sweep path based on the object you select.
-
Mode
-
Controls whether the sweep action creates a solid or a surface. Surfaces are swept as either NURBS surfaces or procedural surfaces, depending on the SURFACEMODELINGMODE system variable.
-
Alignment
-
Specifies whether the profile is aligned to be normal to the tangent direction of the sweep path.
If the profile is not perpendicular (normal) to the tangent of the start point of the path, then the profile automatically aligns. Enter No at the alignment prompt to prevent this.
-
Base Point
-
Specifies a base point for the objects to be swept.
-
Scale
-
Specifies a scale factor for a sweep operation. The scale factor is uniformly applied to the objects that are swept from the start to the end of the sweep path.
- Reference. Scales the selected objects based on the length you reference by picking points or entering values.
-
Twist
-
Sets a twist angle for the objects being swept. The twist angle specifies the amount of rotation along the entire length of the sweep path.
- Bank. Specifies whether the curve(s) being swept will naturally bank (rotate) along a 3D sweep path (3D polyline, spline, or helix).
