Sweep

Creates a 3D solid by sweeping a closed 2D entity along a path.

Accessing the Command

command bar: sweep

menu bar: Model| 3D Solids | Sweep

toolbar: 3D Solids|

: sweep

Prompts you in the command bar:

Select entities: (Select one or more closed 2D entities)

Entities in set: 1

Select entities: (Select more closed 2D entities, or right click to stop selecting 2D entities)

Select sweep path or [Alignment/Base point/Twist]: (Select a linear 2D entity or choose an option)

The selected closed 2D entities are swept along the path.

Depending on the value of the DELOBJ (Delete Entity) system variable, the defining entities are either retained or deleted or you are prompted whether to keep or delete the source entities.

Command Options

Option	Description
Alignment	By default 2D entities are placed perpendicular to the sweep path automatically. The Alignment option allows to sweep 2D entities at their current orientation. Prompts you: Align sweep entity perpendicular to path before sweep? [Yes/No]<Yes>: Yes: The sweep entity is aligned perpendicularly No: The sweep entity is not rotated. In the images above a circle is swept along a helix path. Left: Alignment is ON (circle is placed perpendicularly to the sweep path) Right: Alignment is OFF (circle is not rotated)
Base point	Defines the point on the sweep entity that follows the path. Prompts you: Specify base point: pick a point in the drawing.
Twist	Specifies a twist angle for the swept entity or entities. The twist angle is the amount of rotation along the entire length of the sweep path. Prompts you: Enter twist angle or [allow Banking for a non-planar sweep path (Bank)] <0>: Do one of the following: Type a value a the command prompt. Select the Bank option: determines whether the swept entities will bank (rotate) naturally along a 3D sweep path (3D polyline, spline, or helix).

Grips Editing

Sweep solids can only be moved using grips.
