Vertices are points in space: they define the
structure of faces. When vertices are moved or
edited, the faces they form are affected as well.
Vertices can also exist independently; such isolated
vertices can b e used to construct faces but are
otherwise invisible when rendering.
At the Editable Mesh (Vertex) sub-object level, you
can select single and multiple vertices and move
them using standard methods.

function. You can also use Weld to combine a
number of vertices to the average position of all
of them.
Alternatively, to combine two vertices that are far
apart, resulting in a sing le vertex that’s in the same
position as one of them, use Target Weld.

1. To u s e Weld:
1. On the Selection rollout, turn on Ignore
Backfacing, if necessary. This ensures that
you’reweldingonlyverticesyoucansee.
2. Select the vertices to weld.
3. If the vertices are very close together, go to
the E dit Geometry rollout > Weld group
and click Selected. If that doesn’t work (you
get a “No vertices within weld threshold.”
message), proceed to the next step.
4. Increase the numeric value to the rig ht of
the Selected button.
This is the threshold value; the minimum
distance that vert ices can be apart from each
other to be welded.
5. Click Selected again.
At this point, one of three things happens:
None, s ome, or a l l of the vertices are welded.

others occurs, proceed to the next step.
6. Continue increasing the threshold value and
clicking Selected until a ll of the vertices are
welded.
2. To u s e Target Weld:
1. On the Selection rollout, turn on Ignore
Backfacing, if necessary. T his ensures that
you’reweldingonlyverticesyoucansee.
2. Find two ver tices you want to weld, and
determine the ultimate location of the
resulting vertex. You can weld any two
vertices, but for best results the two should
be contiguous; that is, they should be
connected by a single edge.
For this example, we’ll call the vert ices A and
B, and the resulting vertex will be at vertex
B’s location.
3. Click the Target button.
The button stays highlighted, to indicate that
you’re now in Target Weld mode.
4. Drag vertex A to Vertex B.
