Synopsis

polyMergeEdge([caching=boolean], [constructionHistory=boolean], [firstEdge=int], [mergeMode=int], [name=string], [nodeState=int], [secondEdge=int])

Note: Strings representing object names and arguments must be separated by commas. This is not depicted in the synopsis.

polyMergeEdge is undoable, queryable, and editable.

Sews two border edges together.
The new edge is located either on the first, last, or between both selected edges, depending on the mode.

Both edges must belong to the same object, and orientations must match (i.e. normals on corresponding faces must point in the same direction).
Edge flags are mandatory.

Return value

stringThe node name.

In query mode, return type is based on queried flag.

Flags

caching, constructionHistory, firstEdge, mergeMode, name, nodeState, secondEdge
Long name (short name) Argument types Properties
mergeMode(mm) int createqueryedit
This flag specifies how to merge, merge mode : at first edge : 0, in between : 1, at last edge : 2.
C: Default is in between.
firstEdge(fe) int createqueryedit
The number of the first edge to merge.
secondEdge(se) int createqueryedit
The number of the second edge to merge.
Common flags
name(n) string create
Give a name to the resulting node.
constructionHistory(ch) boolean createquery
Turn the construction history on or off (where applicable). If construction history is on then the corresponding node will be inserted into the history chain for the mesh. If construction history is off then the operation will be performed directly on the object.
Note: If the object already has construction history then this flag is ignored and the node will always be inserted into the history chain.
caching(cch) boolean createedit
Toggle caching for all attributes so that no recomputation is needed
nodeState(nds) int createqueryedit
Defines how to evaluate the node.
  • 0: Normal
  • 1: PassThrough
  • 2: Blocking
  • 3: Internally disabled. Will return to Normal state when enabled
  • 4: Internally disabled. Will return to PassThrough state when enabled
  • 5: Internally disabled. Will return to Blocking state when enabled
Flag can appear in Create mode of command Flag can appear in Edit mode of command
Flag can appear in Query mode of command Flag can have multiple arguments, passed either as a tuple or a list.
