pymel.core.modeling.polyAppend

polyAppend(*args, **kwargs)

Appends a new face to the selected polygonal object. The first argument must be a border edge. The new face will be automatically closed. Only works with one object selected.

Flags:

Long name (short name)		Argument Types	Properties
append (a)		[, <type ‘float’>, <type ‘float’>, <type ‘float’>, ]
	Appends to the given polygon object. The append flag should be used multiple times to specify the edges, points, and holes that make up the new face that is being added. You may specify an edge by passing a single argument which will be the edges index. A point is specified with three arguments which are the coordinates of the point in the objects local space. Pass no arguments indicates that the values which follow shall specify a hole. In Python, pass an empty tuple to specify no arguments. Common flags
constructionHistory (ch)		bool
	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. Flag can have multiple arguments, passed either as a tuple or a list.
edge (ed)		int
	Adds the given edge of the selected object to the new face. This edge must be a border, which will be then shared by the new face and the neighboring one. The new face is oriented according to the orientation of the given edge(s). Note that this flag should be avoided in Python. You may use the appendflag instead and pass one argument.
hole (hl)		bool
	Add a hole. The following points and edges will define a hole. Note that this flag should be avoided in Python. You may use the appendflag instead and pass an empty tuple ().
name (n)		unicode
	Give a name to the resulting node.
point (p)		float, float, float
	Adds a new point to the new face. Coordinates of free points are given in the local object reference. Note that this flag should be avoided in Python. You may use the appendflag instead and pass three arguments.
subdivision (s)		int
	This flag specifies the level of subdivisions. Automatically subdivides new edges into the given number of edges. Existing edges cannot be subdivided. C : Default is 1 (no subdivision). Q: When queried, this flag returns an int.
texture (tx)		int
	Specifies how new faces are mapped. 0 - None; 1 - Normalize; 2 - Unitize C: Default is 0 (no mapping). Q: When queried, this flag returns an int

Example:

import pymel.core as pm

pm.polyCreateFacet( p=[(0, 0, 0), (10, 0, 0), (10, 10, 0), (0, 10, 0)] )

#add a new triangular facet described by the edge #0, and a free point
pm.polyAppend( a=[0, (5, -5, 0)] )

#add a new quadrangular facet with 2 triangular holes.
pm.polyAppend( a=[1, (20, 0, 0), (20, 10, 0), (), (12, 6, 0), (14, 5, 0), (12, 4, 0), (), (16, 5, 0), (18, 6, 0), (18, 4, 0)] )
