FilterPointsByDistance Op Property Editor

Welds together vertices that are within a specified distance from each other.

To apply: Select some points on a polygon mesh and choose Modify Poly. Mesh Filter Points from the Model toolbar.

To redisplay: Select the filtered polygon mesh object, click the Selection button on the Select panel, then click the FilterPointsByDistance Op icon.

Nb Points

Displays the number of points in the resulting mesh. This value is for information only; it cannot be changed directly, but will change as a result of other settings.

Distance

The maximum distance between points for them to be welded together. Values are in Softimage units.

Targets

Specifies the position of the resulting, welded vertices:

Average position welds points in the selection together at their average position.
Selected point welds points in the selection together at the current position of one of the points.
Unselected point welds each selected point to an unselected point on the same object.

Cleanup

Remove new double-sided polygons	Eliminates pairs of back-to-back polygons created by the filtering process. These double-sided polygons can occur where two polygons face each other across a narrow gap. In most situations, you probably don't want such double-sided polygons in the final result, so its best to leave this option on. However, you can turn it off if you intend to use the resulting polygons for further modeling.
Collapse new double edges	Removes double edges created by the filtering process. You can turn this option off, for example, if you want to weld two rows of non-boundary points without collapsing them all to a single vertex.
Border points only	Welds only points on boundary edges, even if non-border points were included in the selection. This option is useful, for example, when joining pieces that were modeled separately and then merged into a single object.
Max normal angle difference	Welds two points only if the difference between their normal angles is less than the specified amount. This option can be used to prevent points that are facing in opposite directions from being welded together. Activate the checkbox and then adjust the slider. Values are in degrees.
Connected user target cluster	Specifies a cluster of points that act as "preferred targets" and are never collapsed to other points. Click the connection icon, then choose Connect and pick a cluster, or choose Disconnect.
