Duplicate along Edge¶
destination after Beta: Modifier Change
Functionality¶
This node creates an array of copies of one (donor) mesh and aligns it along given recipient segment (edge). Count of objects in array can be specified by user or detected automatically, based on size of donor mesh and length of recipient edge. Donor mesh can be scaled automatically to fill all length of recipient edge.
Donor objects are rotated so that specified axis of object is aligned to recipient edge.
This node also can output transformation matrices, which should be applied to donor object to be aligned along recipient edge. By default, this node already applies that matrices to donor object; but you can turn this off, and apply matrices to donor object in another node, or apply them to different objects.
Inputs¶
This node has the following inputs:
 Vertices. Vertices of the donor mesh. The node will produce nothing if this input is not connected.
 Edges. Edges of the donor mesh.
 Polygons. Faces of the donor mesh.
 Vertex1. First vertex of recipient edge. This input is used only when “Fixed” input mode is used (see description of
Input mode
parameter below).  Vertex2. Second vertex of recipient edge. This input is used only when “Fixed” input mode is used.
 VerticesR. Vertices of the recipient mesh. This input is used only when “Edges” input mode is used.
 EdgesR. Edges of the recipient mesh. These edges will be actually used as recipient edges. This input is used only when “Edges” input mode is used.
 Count. Number of objects in array. This input is used only in “Count” scaling mode (see description of
Scale mode
parameter below).  Padding. Portion of the recipient edge length that should be left empty from both sides. Default value of zero means fill whole available length.
Parameters¶
This node has the following parameters:
Parameter  Type  Default  Description 

Scaling mode  Count or Up or Down or Off 
Count 

Orientation  X or Y or Z  X  Which axis of donor object should be aligned to direction of the recipient edge. 
Input mode  Edges or Fixed  Edges 

Scale all axes  Bool  False  If False, then donor object will be scaled only along axis is aligned with recipient edge direction. If True, objects will be scaled along all axes (by the same factor). 
Apply matrces  Bool  True  Whether to apply calculated matrices to created objects. 
Count  Int  3  Number of objects in array. This parameter can be determined from the corresponding input. It is used only in “Count” scaling mode. 
Padding  Float  0.0  Portion of the recipient edge length that should be left empty from both sides. Default value of zero means fill whole length available. Maximum value 0.49 means use only central 1% of edge. 
Outputs¶
This node has the following outputs:
 Vertices
 Edges
 Polygons
 Matrices. Matrices that should be applied to created objects to align them along recipient edge. By default, this node already applies these matrices, so you do not need to do it second time.
This node will output something only when Vertices
or Matrices
output is connected.
Examples of usage¶
Cylinders duplicated along the segment between two specified points:
Spheres duplicated along the edges of Box:
