To create the intersection of geometry objects, in the Geometry toolbar, from the Boolean and Partitions () menu, select Intersection (). You can also right-click the Geometry node to add this node from the Boolean and Partitions submenu. Then enter the properties of the intersection operation using the following section:

Select the geometry objects that you want to intersect in the Graphics window. The objects appear in the Input objects list. If the geometry sequence includes user-defined selections above the Intersection node, choose Manual to select geometry 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.

To create a geometry object without interior boundaries, clear the Keep interior boundaries check box. This can be useful to simplify a geometry where the interior boundaries do not separate domains with different physics nodes or materials, for example.

The Keep lower-dimensional intersections check box is cleared by default, which means that a geometric entity that was created by the intersection operation is removed if its dimension is less than the dimensions of the input entities it originates from. Select this check box to keep also such lower-dimensional entities (for example, an edge resulting from the intersection of two faces).

You can change the settings for the Repair tolerance list if you experience problems with the intersection operation. Geometric entities that have a distance less than the repair tolerance are merged.

When you build this feature, the relative and absolute repair tolerances are set to the values that are used (with a precision of two digits), which can be useful when you have set Repair tolerance to Automatic.

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. From the Color list, choose a color for highlighting the resulting objects selection. See Selection Colors.

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 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.
