Synopsis

polyMergeVertex [-alwaysMergeTwoVertices boolean] [-constructionHistory boolean] [-distance double] [-name string] [-texture boolean]

polyMergeVertex is undoable, queryable, and editable.

Merge vertices within a given threshold.
Since this allows merging any vertices that lie on the same object it is possible for the resulting geometry to be non-manifold.
First, perform comparison of pairs of selected vertices. Pairs that lie within given distance of one another are merged, along with the edge between them.
Second, any selected vertices which share an edge are merged if the distance between them is within the specified distance.
Unlike Merge Edges, Merge Vertices will perform the merge even if the edges adjoining the vertices do not have matching orientation (i.e. normals of adjacent faces do not point in the same direction). As this restriction is not enforced while merging vertices, resulting geometry can be non-manifold.
If alwaysMergeTwoVertices is set and there are only two vertices, tolerance is ignored and the vertices will be merged.

Resulting mesh may have extra vertices or edges to ensure geometry is valid.

Flags

alwaysMergeTwoVertices, constructionHistory, distance, name, texture

Long name (short name) [argument types] Properties

-distance(-d) double

This flag specifies the distance within which vertices will be merged.
C: Default is 0.0 (i.e. vertices are coincident).
Q: When queried, this flag returns a double.

In query mode, this flag needs a value.

-alwaysMergeTwoVertices(-am) boolean

This flag specifies whether to always merge if only two vertices are selected regardless of distance.
C: Default is false.
Q: When queried, this flag returns a boolean.

In query mode, this flag needs a value.

-texture(-tx) boolean

This flag specifies whether the texture is sewn in addition to the 3d edge
C: Default is true.
Q: When queried, this flag returns a boolean.

In query mode, this flag needs a value.

-name(-n) string

Name the resulting object.

-constructionHistory(-ch) boolean

Turn the construction history on or off (where applicable).
Q: When queried, this flag returns an int.

In query mode, this flag needs a value.

Flag can appear in Create mode of command	Flag can appear in Edit mode of command

Return value

string The node name.
