FIGURE 14.16
All the Edge specific commands are available when the Edge subobject mode is enabled. Many of the Border
subobject commands are the same as those for Edges.

Insert Vertices

You also can access the caddy for the Bridge feature. This caddy offers the options to Bridge Specific Edges
or to Use Edge Selection. The Bridge Specific Edges option has two buttons for each edge. If you click one
of these buttons, you can select an edge in the viewport. The Use Edge Selection option lets you drag a mar-
quee in the viewport to select the edges. The Bridge Edges caddy also includes options for setting the num-
ber of Segments, the Smooth value, and a Bridge Adjacent value, which increases the triangulation for
angles above the given threshold.

Split and Insert Vertex
The Split button adds a new vertex at the middle of the edge and splits the edge into two equal sections.
This button is handy when you need to increase the resolution of a section quickly.
The Insert Vertex button lets you add a new vertex anywhere along an edge. The cursor changes to crosshairs
when it is over an edge. Click to create a vertex. When in Edge, Border, Polygon, or Element subobject mode,
this button also makes vertices visible. Within the Ribbon’s Edges pane, you can set the number of vertices to
be placed evenly along the selected edges using the number spinner next to the Insert Vertices tool.
Create Shape from Selection
The Create Shape from Selection button creates a new spline shape from selected edges. You can also select
options for Smooth or Linear shape types.
Spin
The Spin button rotates the hidden edges that break up the polygon into triangles (all polygonal faces
include these hidden edges). For example, if a quadrilateral (four-sided) face has a hidden edge that runs
between vertices 1 and 3, then the Spin button changes this hidden edge to run between vertices 2 and 4.
This affects how the surface is smoothed when the polygon is not coplanar.
Cap Poly
The Cap Poly button that appears in the Geometry (All) panel causes the existing border selection to be
filled in with a single coplanar polygon. After using this feature, the Border subobject is no longer identified
as a Border subobject.
Bridge
The Bridge feature joins two selected Border subobjects with a tube of polygons that connect the two borders.
The two selected borders must be part of the same object and need not have an equal number of segments.
