Extend dialog box

Makes surfaces larger in one or more directions by specifying a distance or a termination plane.

Access:

Ribbon: 3D Model tab Surface panel Extend

	Edges selects and highlights each face edge of a single surface or quilt for extension. Note: If the boundary of a selected face has additional edges on update, those edges are not automatically added to the extend feature.
Edge Chain	Automatically extends a selected edge to include all edges that are tangent continuous to the selected edge. Edge chaining stops when an edge that is not tangent continuous to the selected edge is detected.
Extents	Determines the method for ending the extension and sets its depth. Click the arrow to select an extent method from the list. Distance default method. Extends edges at a specified distance. Enter a value or drag the direction arrow to extend the surface dynamically. To selects an ending face (of a solid or surface body) or work plane on which to terminate the extension. Optionally, once the termination face is selected, clear the check box to terminate to the entire body rather than just the selected face.

Edge extension

Controls the method used to extend the edges that are adjacent to the surface edges to extend. Extend creates extended edges along the curve direction of edges adjacent to the selected edges. Stretch creates extended edges in a straight line from the edges adjacent to the selected edges.
