Object Properties

The Details Pane for this object includes the following properties.

Category	Property/Options/Descriptions
Definition	Connection Type: Read-only field that describes the bearing - Body-Ground Stiffness K11, K22, K12, K21: Entry fields. Damping C11, C22, C12, C21: Entry fields. Suppressed
Reference	Rotation Plane: Specify the desired plane of rotation. Options include: None (Default) X-Y Plane Y-Z Plane X-Z Plane
Mobile	Scoping Method: Specify as Geometry Selection, Named Selection, or Remote Point. Based on the selection made for the Scoping Method property of this category, the next property is: Scope: Appears if Scoping Method is set to Geometry Selection. Select a geometry entity and then click Apply. Mobile Component: Appears if Scoping Method is set to Named Selection. This property provides a drop-down list of available user-defined Named Selections. Remote Points: Appears if the Scoping Method is set to Remote Point. This property provides a drop-down list of available user-defined Remote Points. Body: Read-only indication of scoped geometry. Coordinate System: Drop-down list of available coordinate systems. Global Coordinate System is the default. The following read-only properties display the coordinates of the centroid location for the scoped geometric entities from the origin of the coordinate system selected in the Coordinate System property. Mobile X Coordinate Mobile Y Coordinate Mobile Z Coordinate Behavior: Rigid (default), Deformable, or Beam. If the Scope Method property is set to Remote Point, the Bearing will then assume the Behavior defined in the referenced Remote Point as well as other related properties. Material: Available when the Behavior property is set to Beam. Select a material to define material properties for the beams used in the connection. Density is excluded from the material definition. Radius: Available when the Behavior property is set to Beam. Specify a radius to define the cross section dimension of the circular beam used for the connection. Pinball Region: The Pinball Region is a radius value (length unit) that defines a region for selecting elements to be used by the solver for the Bearing's Mobile scoping. Note: The Pinball Region and Behavior settings are: Applicable to underlying bodies that are flexible. Not applicable to a bearing scoped to the vertex of line body.
