Inputs
Connect the geometry where the polygons should be separated here. This geometry remains unchanged as the separated polygons are managed in a new geometry.
Here you can route the indices of the polygons or points to the Node to be separated. If you would like to access an already saved selection or an active selection, for example, you can also use the Selection Range as an alternative. You define whether the indices are to be related to points or polygons in the Mode setting.
Here you choose whether the defined selection should be applied to the points or polygons of the geometry. When defining a point selection, please note that all points of a polygon must be selected for the corresponding polygon to be separated.
Here you can, for example, use the name of a selection in quotation marks that you want to read out, e.g., "MySelection". Otherwise, the default entry will use an active selection on the geometry.
You can also use special keywords and logical operations here to create a new selection from scratch or a combination of already saved selections. The following keywords and operations can be used:
- Default: This term causes an active selection currently present on the geometry to be used. If no selection is active, all points will be used.
- odd: This term is used to select all elements that have an odd index number.
- even: This term is used to select all elements that have an even index number.
- all: This selects all elements of the selected type.
- hidden: Selects the hidden elements of the geometry.
- Name of a saved selection: If you enter the name of a saved selection in quotation marks, this selection will be read and used. To use a combination of a saved selection and another keyword or selection, use quotation marks with the selection name.
- Index numbers: You can also use index numbers directly, just as you are used to from the Index Array From String Node.
- Mathematical and logical operations: Mathematical or logical operations can be used to combine selections. Using the string odd – "center" for instance selects all odd elements and then subtracts the selection that has been stored by the name "center". You can use +, -, & (logical and), | (logical or) as well as a comma to combine multiple selections or index sequences.
This can be used to reverse the polygon selection for cutting. The unselected polygons are then separated into a new geometry.
