Inter face
Weld nearby ver tices—Sets whether to weld nearby
vertices of conv erted objects according to the Weld
Threshold setting. Welding smooths across seams
and unifies normals of objects with coincident
vertices. Welding occurs only on vertices that are
part of the same object.
Weld t hr e sho ld —Sets the distance that determines
whether vertices are coincident. If the distance
between two vertices is less than or equal to the
weld threshold, the vertices are welded together.

Auto-smooth a dja cent f a ce—Assigns smoothing
groups (page 3–1013) according to the
Smooth-angle value. Smoothing groups
determine w hether faces on an object render as a
smooth surface or display a seam at their edges,
creat ing a faceted appearance.
Smooth-angl e—Controls whether smoothing
occurs b e tween two adjacent faces. If the angle
between the two face normals is less than or equal
to the smooth angle, the faces are smoothed (that
is, put in the same smoothing group).
Orient nor mals of adjacent faces
consistently —
Analyzes the face normals of
each object and flips normals where necessary,
so they all point in a direction that is consistent
w ith adjoining faces. If the imported geometry
isn’t properly welded, or if the AutoCAD geometry
did not contain or specify normal information,
normals might be oriented in the wrong direction.
Use the Edit Mesh (page 1–634) or Normal (page
1–746)modifiers to flip normals.
When Unify Normals is off, norma ls are calculated
according to the face vertex order in the linked
file. Face norma ls for AutoCAD solids are already
unified. Turn off Unify Normals when importing
only Au toCAD solid models fr om Architectural
Desktop.
Cap closed splines—Applies an Extrude modifier
(page 1–680) to all closed objects, and selects the
Cap Start and Cap End options of the modifier.
The Extrude modifier Amount value for a closed
objectwithnothicknessissetto0.Cappingmakes
closed objects with thickness appear solid and
closed objects without thickness appear flat. When
Cap Closed Objects is off, the Extrude mo difier
CapStartandCapEndoptionsforclosedobjects
w ith thickness are clear. No modifiers are applied
to closed objects without thickness.
