Bounding Volume Strategy dialog box

Entity Types
You must select at least one check box in the Entity Types group in order to complete the bounding volume strategy. These check boxes are available when you create or clone a selection recipe.
Input Filter	Appears when you create, edit, or clone a single-strategy selection recipe, or when you add the first strategy to a stacked selection recipe. Available when you create or clone a selection recipe.Specifies where the entities that you want to select exist.The listed options vary, depending on whether the Simulation file or FEM file is the displayed part.Selecting any option other than Entire Model limits the scope of the strategy.
Select Object	Appears when Input Filter is set to Mesh, Polygon Body, or Component.Lets you select the mesh, polygon body, or component FEM where the entities that you want to select exist.
Select All	Selects the check boxes for all of the listed entity types.You can clear individual check boxes as needed.
Deselect All	Clears the check boxes for all of the listed entity types.You can select individual check boxes as needed.

Bounding Volume Definition
Method	Available when you create or clone a selection recipe.Specifies the technique to use to define the bounding volume.Box - CSYS and Edge LengthsCreates a box using the origin of the selected coordinate system to define the origin of the box and the specified dimensions to define the size of the box.Box - Two Diagonal PointsCreates a box using two diagonal points to define the opposite corners. The software creates a box with edges parallel to the axes of the work coordinate system.Box - Two Points on View PlaneCreates a box using two diagonal points to define a rectangle on the plane that is parallel to the screen.You can specify a depth for the box, or you can extend it infinitely in the direction normal to the view plane. If you use an infinite depth, the symbol for the bounding volume in the graphics window remains a 2D box.If you use the Box - Two Points on View Plane method to create the bounding volume strategy and subsequently edit that strategy, the method automatically changes to Box - CSYS and Edge Lengths. This enables you to modify the dimensions of the bounding volume. If the strategy originally used an infinite depth, you must modify the origin of the coordinate system in order to correctly position the bounding volume.Cylinder - CSYS, Diameter and HeightCreates a cylinder using the origin of the selected coordinate system to define the origin of the cylinder and the specified diameter and height to define the size of the cylinder.You can optionally create only a portion of a cylinder. To do so, select the Start Angle and End Angle check boxes, and set the beginning and ending of the cylinder segment as described below.Cylinder - End Points and DiameterCreates a cylinder using the specified points for the center of the base and top of the cylinder, as well as the specified diameter.Cylinder - Origin and Diameter on View PlaneCreates a cylinder using a point on the plane that is parallel to the screen and a specified diameter. You can specify a depth for the cylinder, or you can extend it infinitely in the direction normal to the view plane. If you use an infinite depth, the symbol for the bounding volume in the graphics window remains a 2D circle.If you use the Cylinder - Origin and Diameter on View Plane method to create the bounding volume strategy and subsequently edit that strategy, the method automatically changes to Cylinder - CSYS, Diameter and Height. This enables you to modify the dimensions of the bounding volume. If the strategy originally used an infinite depth, you must modify the origin of the coordinate system in order to correctly position the bounding volume.Sphere - Origin and DiameterCreates a sphere using the specified point as the center and the specified diameter.Arbitrary Volume - Polygon Body or 3D MeshCreates a box that encompasses a selected polygon body or 3D mesh.The size of the bounding volume adjusts automatically if the size of the body or 3D mesh changes.Note: If you select a polygon body that has a curved surface, the selection recipe might not select certain entities, depending on their location. If the selection recipe does not produce the expected results, you might have to use the Inside/Crossing containment option or select a 3D mesh instead. However, using a 3D mesh can significantly increase the time it takes to load and work with the model.
