Select, S cale, and R otate Control Points—Lets
you select, scale, and rotate control points of a
cross sect ion in the Cross Section view.
This is comparable to using the Move transform
on geometry in viewports. Control points are
simultaneously scaled and rotated around the link,
which in effect "moves" them.
SelectacrosssectionintheProfileviewfirst.Then
select and move control points in the Cross Section
view to change the bulge.
Sel ect and R otate Control Points —Lets you
select and rotate control points in and around the
center of the link in Cross Section view.
This does
not twist the mesh . If the cross section is
not a circle, a bulge migrates around t he mesh.
Select and S cale Control Points—Lets you
select and scale control points about the link’s
center in the Cross Section view.
If all cross section cont rol points are scaled, the
mesh bulges uniformly.
Draw Control Points—Lets you add control
points by dr awing freehand in the Cross Section
v iew. T he shape of the bulge changes based on t he
shape you draw.

resolution step. You can freeze existing control
points by selecting them in the Cross Section view
and holding down the CTRL key as you draw.
Note: The number of control points created
dependsonthecrosssectionResolution(see
Cross
Sections panel (p age 2–972)
).
Tip: YoucanalsousethistooInProfileview.When
you draw in Profile view , you change the profile
of the bulge while placing a control point on each
cross section of the bulge angle. This is useful
mainlywhenthebulgeangleusesmultiplecross
sections. You can rotate the orientation bar to
draw whichever profile you desire. (Imagine the

Insert Control Points—Lets you insert control
points by clicking t he cross section in the Cross
Section view. A single control point is created each

green profile reference points at the top and
bottom of Cross Section view. In other words,
clicking this button causes the bulge to appear on
