Extracts and outputs the specified x, y, and z attributes of a feature's point that is either in the center of the feature's bounding box, somewhere inside the feature's bounding box or at the center of mass of the feature.
Output Port
Output
This port outputs the result of the extracted x, y, and z attributes. If NULL geometry is passed in, then the x, y, and z attributes will not be outputted.
This port outputs null geometry features, and whenPoint Extraction ModeisInside, all non-area geometry features.
Parameters
Mode
Center Point
Extracts the specified x, y, and z attributes of a feature's point that is in the center of the feature's bounding box.
Center of Gravity Point
Extracts the specified x, y, and z attributes of a feature's point at the center of mass of the feature. Note that, depending on the feature’s shape, the resulting point may be far outside of the original feature.
Example
The transformer calculates the exact distribution of portions of a shape; therefore, some points can actually appear outside a feature.
Inside Point
Extracts the specified x, y, and z attributes of a point that is guaranteed to be inside the area.
Usage Notes
Note that, depending on the feature's shape, the resulting point may be far outside of the original feature.
Editing Transformer Parameters
使用一组菜单选项,变压器参数s can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click
beside the applicable parameter. For more information, seeTransformer Parameter Menu Options.
