To weld polygon ver tices:

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 single vertex that’s in the s ame
position as one of them, use Target Weld.
1. To u s e Wel d :
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, simply
click Weld. If that doesn’t work, proceed to
the next step.
4.
Click the Settings button to the right of
the Weld button.
This opens the
Weld Vertices dialog (page
1–1078)
.
5. Increase the Weld Threshold value gradually
using the spinner (click a nd hold on the
up-down arrow buttons to the right of the
numeric field and then drag upward). If you
need the value to change more quickly, hold
down the CTRL key as you drag.
When the threshold equals or exceeds
the distance between two or more of the
vertices, the weld occurs automatically, and
the resulting vertex moves to their average
location.
6. If not all the ver tices are welded, continue
increasing the Weld Threshold value until
they are.
7. Click OK to exit.
2. To u s e Ta rg e t We l d :
1. On the S elec tion rollout, turn on Ignore
Backfacing, if necessary. This ensures that
you’reweldingonlyverticesyoucansee.
2. Find two vert ices you want to weld, and
determine the ultimate location of the
resulting vertex. The two vertices must be
cont iguous; that is, they must be connected
by a single edge.
For this example, we’ll call the vertices A and
B, and the resulting vertex will be at vertex
B’s location.
3. Click the Target Weld button.
The button stays highlighted, to indicate that
you’re now in Target Weld mode.
4. Click vertex A and then move the mouse.
A rubber-band line connects the vertex and
the mouse cursor .
5. Position the cursor over vertex B, whereupon
the cursor image changes from an arrow
to a crosshairs. Reminder: Only vert ices
connected to the first vertex by a single edge
qualify for target welding.
6. Click to weld the two.
The resulting vertex remains at vertex B’s
position, and you exit Target Weld mode.
