Split
The Split () operation splits an object into its entities:
•
A solid splits into solids corresponding to its domains.
•
A surface object splits into surface objects corresponding to its faces.
•
A curve object splits into curve objects corresponding to its edges.
•
A point object splits into point objects corresponding to its vertices.
•
A general (mixed) object splits into solids (corresponding to the domains), surface objects (corresponding to faces not adjacent to a domain), curve objects (corresponding to edges not adjacent to a face or domain), and point objects (corresponding to vertices not adjacent to an edge, face, or domain).
To split geometry objects into their entities, in the Geometry toolbar, from the Conversions menu, select Split (). Then enter the properties of the split operation in the Input section.
Input
Select the geometry objects to split on in the Graphics window. The objects appear in the Input objects list. If the geometry sequence includes user-defined selections above the Split node, choose Manual to select objects, or choose one of the selection nodes from the list next to Input objects.
Click the Active button to toggle between turning ON and OFF the Input objects selections.
Select the Keep input objects check box to use the selected geometry objects for further geometry operations.
Selections of Resulting Entities
Select the Resulting objects selection check box to create predefined selections (for all levels — objects, domains, boundaries, edges, and points — that are applicable) in subsequent nodes in the geometry sequence. To also make all or one of the types of resulting entities (domains, boundaries, edges, and points) that the resulting objects consist of available as selections in all applicable selection lists (in physics and materials settings, for example), choose an option from the Show in physics (Show in instances if in a geometry part; Show in 3D in a plane geometry under a work plane in a 3D component) list: All levels, Domain selection, Boundary selection, Edge selection, or Point selection. The default is Domain selection, which is suitable for use with materials and physics defined in domains. For use with a boundary condition, for example, choose Boundary selection. These selections do not appear as separate selection nodes in the model tree. Select Off to not make any selection available outside of the geometry sequence.
Cumulative Selection
If you want to make the resulting entities contribute to a cumulative selection, select a cumulative selection from the Contribute to list (the default, None, gives no contribution), or click the New button to create a new cumulative selection (see Cumulative Selections). From the Color list, choose a color for highlighting the resulting objects selection. See Selection Colors.
Selections on Input Objects
If you have Named Selections that include entities on the input objects, select the Propagate selections to resulting objects (selected by default) check box to update the selections to corresponding entities on the output objects, when possible. Clear the check box to not propagate the selection to the resulting objects. This can be useful in combination with selecting the Keep input objects check box so that the selections refer only to the input objects.
Assigned Attributes
From the Construction geometry list choose On to make the resulting objects available only in the feature’s geometry sequence. The default option Inherit means that the resulting objects become construction geometry if all input objects are construction geometry. Choose Off to never output construction geometry objects. For more information, see Construction Geometry.
