Vertex Weld Modifier 935
Channel group
Specifies whether to apply the transform to a
mapping channel or a vertex color channel, and
which channel to use. For more information on
these channels, see UVW Map Modifier (page
1–922).
Ma p Channel—Specifies a UVW channel to use for
the mapping, an d use t he spinner to its right to set
the channel number.
Ver tex Color Channel—Uses the vertex color
channel for the mapping.
Apply To Entir e Object—If the UVW Xform
modifier is applied to an active sub-object
selection, such as face or patch, this switch controls
whether the settings of the UVW Xform modifier
affect only the original sub-object selection or
affect the entire object.

The Vertex Weld modifier behaves like the Weld
featureinEditableMeshorEditablePatchand
welds all vertices that fall w ithin the threshold
setting. Vertex Weld is very usef ul for cleaning
up meshes that have vertices that are close or
overlapping, but not welded.

Procedure
Ex ample: To apply t he Ver t ex Weld modi fi er to a
mesh :
1.
Create a box with Leng th, Width, and Height
set to 40.
2. Right-click the box and choose Convert to >
Convert to Editable Poly.
3. Set the sub-object mode to polygon, and select
Polygon 6.
Tip: Watch the listing at the bottom of the
Selection rollout to see which polygon is
selected.
4. Delete polygon 6.
By deleting the polygon, you create an open
mesh.
5. Apply a Turn To Poly modifier, and set the
Selection Level to Object.
6. Apply a Mirror modifier , and set Mirror Axis
to X.
7. Turn on Copy, and set Offset to –40.
The reflection of the box shares a common
seam but the vertices along the seam are not
welded.
8. Apply a Vertex Weld modifier to cement the
two boxes into one element.
Note: This combination of steps can be streamlined
by using the Symmetry modifier (page 1–861),
which will mir ror the mesh and weld it in a single
operation.
Interfa ce
Threshold—The value of the Threshold sett ing
delegates how close vert ices can b e before they are
automatically welded together. Default=0.1
