 Iteration: Outputs the index numbers of the points, polygons or edges in the

Selection tag one after the other. Edges are again a special case — for each

edge, the node outputs the index numbers of its points.

Tag

Tag nodes enable you to access the various tags that belong to an object. Choose which type of tag you

want to search for in the Attribute manager. Here, the Tag node searches for a Point Selection tag. Once

found, the tag is passed to a Selection node.

This node outputs an object’s tags. Connect the object whose tags you want to access to the Object

input port. In the Attribute manager, set Tag Type to the type of tag that you want to access. You can

exclude individual tags from the search by dragging and dropping them into the Exclude box in the

Attribute manager.

The following input ports are available:

 First Tag: Usually, all tags that belong to the object are checked, starting with

the rst tag. However, this value enables tags to be skipped. For example, if

First Tag is set to 0, the search begins with the rst tag and all tags are checked.

However, if First Tag is set to 1, the rst tag will be skipped and the search will

begin with the second tag.

 Maximum Tags: Here you can specify the maximum number of tags that the

node will output. For example, a value of 3 means that the node will output

the rst three tags only that match the search criteria. If the port receives the

value 0, the node will output all tags that match the search criteria.

 Object: Here, connect the object whose tags you want the node to output.

 On: The On input port takes a Bool value that enables (True) or disables (False)

the node. The node is enabled automatically if you do not add this port.

The following output ports are available:

 Count: Outputs the total number of tags found. This value depends not only

on the search criteria but also on the value of the Maximum Tags port. (The

Maximum Tags value can limit the number of tags the node outputs, even if

the object has further tags of the desired type).

 Tag: Outputs the tags found.
