SWEEP command

Creates 3D solids or surfaces by sweeping profiles along a path.

BricsCAD Shape; BricsCAD Pro; BricsCAD Mechanical; BricsCAD BIM



Creates 3D solids or surfaces by sweeping profiles (open or closed 2D entities or 3D subentities) along an open or closed path.

Entities accepted as profile entities: 2D splines, 3D splines, 2D polylines, 2D solids, 3D solid faces, 3D solid edges, arcs, circles, ellipses, elliptical arcs, lines, regions, surface and mesh edges, traces.

Entities accepted as a path entity: 2D splines, 3D splines, 2D polylines, 3D polylines, edges of 3D solids, surfaces or meshes, helices, arcs, circles, ellipses, elliptical arcs, lines.

Note: Depending on the value of the DELOBJ system variable, the defining entities are either retained or deleted.


There are two methods to sweep entities:

  • Create 3D solids
  • Create surfaces

Options within the command


Sets the 3D entity type this command will create.

  • Solid: creates 3D solids.
  • Surface: creates surfaces.
Note: Open entities always construct 3D surfaces.
Select sweep path
Select an entity to define the path.

Determines the angle at which the profile 2D entities are swept along the paths.

  • Yes: aligns the sweep entity perpendicularly to the sweep path entity
  • No: the sweep entity maintains its original orientation, and so it’s not rotated along the path.
Base point
Defines the point on the sweep entity that follows the path. This option allows offset sweep paths.

Specifies a twist angle for the swept entity. The twist angle is the amount of rotation along the entire length of the sweep path.

  • Banking: determines whether the swept entities will rotate naturally along a 3D sweep path, such as those made from a 3D polyline, spline, or helix.

Allows to dynamically sweep profiles along a sequence of interconnected linear entities or along a portion of a path.

  • Transform profile: use the Manipulator to move, rotate, mirror or scale the profile.
  • Accept: accepts the current position of the profile.
  • Move cursor along selected edge: the profile is swept dynamically along the path or path segment.
  • Select adjacent edge: click when the next segment highlights to continue.
  • Undo: removes the last segment.
