Extending and extruding surface edges

To offset or extrude a face

1. Select the PullTool used to distort or deform geometry. Use the Pull tool to offset, extrude, revolve, sweep, draft, and blend faces; or to round, chamfer, or extrude edges. When converting a sketch to 3D, pulling a line creates a surface and pulling a surface creates a solid. tool in the Edit group on the Design2D or 3D model that contains at least one top-level component. tab. The Select tool guide on the right side of the Design windowArea in the user interface that displays your model or assembly. Also known as Workspace. should be active.

2. Select the face or surface you want to offset or extrude.

   You can select multiple surfaces and faces of solids to offset or extrude them simultaneously.

3. (Optional) Add edges to your selection.

   Select the edges of the face that you want to extrude when you pull. (Any unselected edges are defined by the neighboring geometry during the pull, creating an offset instead of an extrusion.)

4. (Optional) Select the Direction tool guide , then click the straight line, axis, or edge if you want to offset or extrude in a different direction.

   You can also Alt+click a straight line, axis, plane, origin axis, or edge. Sometimes SpaceClaim guesses your intent incorrectly when you Alt+click the direction line. If this happens, just use the Direction tool guide to correct it.

   The pull direction is shown in blue and the pull arrow is reoriented.

5. Click and drag the face in the direction of the Pull arrow.

    

   Dragging a:	Does this:
   SolidObject that encloses volume. A surface becomes a solid if it encloses volume. face	Offsets the face in its natural offset direction
   Solid face and all its edges	Creates an extrusion
   SurfaceTwo dimensional object that has no thickness (as opposed to a face, which is part of a three-dimensional object). A surface has area but no volume. See FaceSide or other surface of a solid. Some examples are the inside surface of a hole or the six sides of a rectangular solid. See Surface.. face	Thickens or thins the face
   CornerSee FilletRounded corner at the intersection of two lines or edges; concave intersection between two surfaces. Fillet refers to an interior corner; exterior corner is known as a round. You can draw a fillet using the Create Rounded Corner tool or by selecting the Fillet (Constant radius round) option from the Pull options. See RoundRounded corner at the intersection of two lines or edges. Round refers to an exterior corner; an interior corner is known as a fillet. Rounds and fillets are both called rounds. See Fillet, Constant-radius round, Variable-radius round.. (interior corner) or Round (exterior corner) edge of a solid	Creates a round, chamfer, or extrusion, depending on the selected option
   Round or chamfer	Offsets the round or chamfer
   Variable round	Uniformly offsets the variable round
   Cylinder, torus, or cone	Offsets the cylinder, torus, or cone

    

   To dimension the offset, type the distance you want to pull and press Enter.

   Press and hold Ctrl to offset a copy of the face as a surface.

   Neighboring faces automatically extend to bound the offset face.

   You can also use the Up To tool guide to pull up to any edge, plane, surface, or face in your design. If you pull a round, chamfer, or cylinder with the Up To tool guide, and pull up to similar geometry, the radius or offset is changed to the dimension of the Up To face you select.

Options

The following options are available in the Pull tool. Once you select the edge or face to pull, select these options from the Options panelArea of the user interface that enables you to modify functions specific to tools., or right-click and select them from the mini-toolbar:
