Extrude Surface 1191
Extrude Surface rollout (creation time )
Amount—The distance the surface is extruded
fromtheparentcurveincurrent3dsMaxunits.
This parameter is animatable.
Direction group
X, Y and Z—Choose the axis of extrusion.
Default=Z.
Start PointAdjusts the position of the curve’s
start point. This can help eliminate unwanted
tw ists or "buckles" in the surface.

Flip Normals—Lets you flip the surface normals
at creation time. (After creation, you can flip
normals using controls in the Surface Common
rollout.)
Cap—When on, two surfaces are generated to close
theendsoftheextrusion.Whiletheyarepresent,
the cap surfaces are m aintained so they match the
dimensions of the extrude surface. The parent
curvemustbeaclosedcurve.
The Cap check box appears
only
on the creation
rollout. If you want to remove the caps later, simply
select them as surface sub-objects and delete them.
Think of extrude capping as a workflow shortcut
rather than a property (or parameter) of extrude
surfaces.
To flip the normal of an extrude cap, select it as a
Surface sub-object and use the Flip Normals toggle
on the Surface Common rollout.
Extrude Sur face rollout (modification time)
Amount—Thedistancethesurfaceisextruded
from the p arent curve in current 3ds Max units.
Direction group
X, Y a nd Z— Choose the axis of extrusion.
Default=Z.
Start PointAdjusts the position of the curve’s
start point. This can help eliminate unwanted
tw ists or "buckles" in the surface.
This control is disabled if the curve is not a closed
curve.

Replace Base Curve—Lets you replace the parent
