Hinge Setti ngs—Opens the Hinge From Edge
dialog (page 1–1073),whichletsyouhinge
polygons via interactive manipulation.
If you click this button after performing a manual
hinge, the dialog opens with Angle set to the extent
of the last manual hinge.
Extr ude Along S pline—Extrudes the current
selection along a spline.
You can ex tru de a single face (1) or a selection of contiguous
(2) or non-contiguous faces (3). Extrusion 2 uses Taper Curve
and Twist. Extrusion 3 uses Taper Amount; each ex trusion has
a different cur ve rotation.
Make a selec tion, click this button, and the select a
spline in the scene. The selection is extruded along
the spline, using the spline’s current orientation,
but as though the spline’s st art point were moved
to the center of each polygon or group.
Ex trude A long Spline Settings—Opens the
Extrude P ol ygons Along Spline dialog (page
1–1071),whichletsyouextrudealongsplinesvia
interactive manipulation.
Edit Triangulation—Lets you mo dify how polygons
are subdivided into triangles by drawing internal
edges.
In Edit Triangulation mode, you can see the current
triangulation in the viewport, and change it by clicking two
vertices on the s ame polygon.
To manually edit triangulation, turn on this
button. The hidden edges appear. Click a polygon
vertex. A rubber-band line appears, attached to
the cursor. Click a non-adjacent vertex to create a
new triangulation for the polygon.
Retr iangulate—Lets the s oftware automatically do
its best triangulation on the polygon or polygons
currently selected.
Retriangulate attempts to optimize how selected polygons are
subdivided into triangles.
Tu rn—Lets you mo dify how polygons are
subdivided into triangles by clicking diagonals.
When you activate Turn, the diagonals (page
3–928) become visible as dashed lines in wireframe
and edged-faces views. In Turn mode, click a
diagonal to change its position. To exit Turn mode,
right-click in the viewport or click the Turn button
again.
