Built-In S ection list—Clicking the arrow button for
this list displays common structural sections.
• Angle section—Sweeps a
structural angle section along the spline.
Default section=Angle.
•
Bar section—Sweeps a 2D
rectangular section along the spline.
•
Channel section—Sweeps a
structural channel section along the spline.
•
Cy linder section—Sweeps a
solid 2D circle section along the spline.
•
Half Round section—This
section produces a half round extrusion along
the spline.
•
Pipe section—Sweeps a
circular hollow tube section along the spline.
•
Quar ter R ound section—Useful
for molding details; this section produces a
quarter round extrusion along the spline.
•
Tee section—Sweeps a
structural tee section along the spline.
•
Tub e se c tion—Based on a
square, this sweeps a hollow tube section along
the spline. Similar to the Pipe section.
•
Wide Flange section—Sweeps a
structural wide flange section along the spline.
Use Custom S ecti on—Choose this if you’ ve created
your own section or there is another shape in the
current scene or in another MAX file that you’d
like to use as your section.
Note: Using a 2D shape as the Sweep modifier’s
custom section will yield the most predictable
results. If using a 3D shape as the custom section,

Pick —If the custom shape you want to u se is visible
in the viewport, click the Pick button and then
pick the shape directly from the scene.
Pick Shape—Click the Pick Shape button to open
the Pick Shape dialog (page 1–857).Thisdialog
shows only valid shapes that are cur rently in the
scene.
Ex tract—Lets you create a new shape in the scene
that is either a copy, instance, or reference of the
cur rent custom section. Opens the Extract Shape
dialog (page 1–858).
Merge From File—Lets you choose a section that is
stored in another MAX file. Opens the Merge File
dialog (page 1–859).
