Offsetting and extruding faces

 

You can extend or extrude the edges of any surface with the PullClosed tool. When you extend an edge, the pull extends the neighboring faces without creating a new edge. Extruding an edge creates edges.

 

 

To extend or extrude the edge of a surface

  1. Click PullClosed in the Edit group on the DesignClosed tab. The Select tool guide on the right side of the Design windowClosed should be active.

  2. Select the outside edge of a surface.

    Ctrl+click to select multiple edges.

  3. Click the PullClosed arrow oriented along the surface to extend the edge. Press Tab or click the other PullClosed arrow to extrude the edge in another direction.

  4. (Optional) Ctrl+click the vertex of one or both neighboring edges to ignore their influence.

  5. Drag in the direction of the PullClosed arrow to extend the edge or create a new surface perpendicular to the old one.

    If the correct pull arrow is not highlighted, press Tab or click the PullClosed arrow you want to use.

    The natural direction of a surface edge is in the plane of the surface.

    You can use the Up To tool guide to pull a linear edge up to a face, surface, edge, or point. If the face or surface does not intersect the edge you are pulling, the edge will be pulled parallel to the selected object.

    To dimension the extension, type the distance you want to extend the surface while you are pulling and press Enter.

Options

The following options are available in the PullClosed tool. Once you select the edge or face to pull, select these options from the Options panelClosed, or right-click and select them from the mini-toolbar:

 

Add

Select the Add option to only add material. If you pull in a subtractive direction, no change will occur. You can combine this option with other PullClosed options.

Cut

Select the Cut option to only remove material. If you pull in an additive direction, no change will occur. You can combine this option with other PullClosed options.

No Merge

Pulls without merging into other objects even when the object pulled intersects with an existing object.

Full PullClosed

Extends an edge or face to the nearest face. This option works similar to the Up To tool guide, except you don't select the face to extend to. If used to revolve or sweep, click this option to revolve 360 degrees or to the next face, sweep through the full trajectory, or blend through selected faces.

PullClosed Both Sides

Select a single, detached edge, imprinted edge, or surface, then click this option to pull both sides of the edge or surface at once.

Ruler

Select this option, then click to connect a ruler, oriented along the pull axis, to an anchor edge or face. You can use the ruler to dimension the pull. The direction must be specified to successfully create a ruler dimension. Press Esc to cancel the ruler dimension.

Up to

Pulls the element so it mates with the surface of the selected body or be pulled up to a plane through the selection. You can find this option in the mini-toolbar and it is the same as the Up To tool guide.

ExtrudeClosed EdgeClosed

When you are pulling an edge, select this option to extrude the edge into a surface.

Copy EdgeClosed

When you are pulling an edge, select this option to create a copy of the edge.

Pivot EdgeClosed

When you are pulling an edge, select this option to pivot the edge along the selected PullClosed arrow.

Examples

Pulling the edge of a surface up to another edge forms a solid if it closes the body

 

 

Pulling the edge of a cylindrical surface extends the surface along a cylindrical path (A) unless you hold Ctrl (B).

 

 

Pulling the edge of a cylindrical surface with the No Merge option selected creates a new edge.

 

 

Pulling the edge of a cylindrical surface with the Both Sides option and holding Ctrl creates a new surface tangent to the cylinder and extends in both directions from the edge.
