The Selection Configuration tab contains checks and restrictions for each ancillary.

The Common part of the Selection Configuration tab applies to all ancillaries. The Trunnion Ancillary part of the tab applies only to trunnion ancillaries and becomes active if the support class of the selected ancillary contains the word TRUNNION.
Primary Component
Select the check box to define that the ancillary can be created as a standalone ancillary, not just as an associated ancillary.
If the support class of the currently selected ancillary starts with the word FOR, the check box is deactivated.
Available on Framework
Select the check box to define that the ancillary can be created on a framework.
Only Available on Framework
Select the check box to define that the ancillary is only available on a framework structure.
Minimum Elevation
Specifies the elevation (height) at which an ancillary can be created at and above. For example, setting a value of 5000 means the ancillary can be created at any elevation at 5000mm and above, but not below 5000mm. If a value of -1000 is input, the support can be created at any elevation below 1000mm.
The default setting is *, indicating that there is no restriction on the elevation at which the ancillary can be created.
Pipe Direction
Select the Vertical check box to define that the ancillary can be created on a vertical pipe.
Select the Horizontal check box to define that the ancillary can be created on a horizontal pipe. If the ancillary is allowed on a horizontal pipe, it must pass the maximum slope check.
Select the Ignore Max Pipe Slope check box to define that the ancillary can be created on a pipe with a slope value greater than the defined maximum pipe slope in the Supports application defaults. Refer to Max. Pipe Slope (MDSSUPPMS) for further information.
Component Type
By default, the Supports application positions the trunnion ancillary on the head or the base of the trunnion.
The Head option button indicates that the trunnion ancillary is positioned on the head of the trunnion.
The Base option button indicates that the trunnion ancillary is positioned on the base of the trunnion.
If the trunnion ancillary is in the support class FOR TRUNNION BASE or PIPE REST INLINE, it is defined as a base component. If the trunnion ancillary support class contains the word BASE or BEARING, it is defined as a base component. All other trunnion ancillaries are defined as head components.
Head Components Allowed
The Head Components Allowed part of the tab applies only to trunnion ancillaries and becomes active if the selected ancillary is a trunnion head component.
Select the Tube check box to define that the head component of the trunnion ancillary can be positioned on a pipe tube.
Select the Elbow check box to define that the head component of the trunnion ancillary can be positioned on an pipe elbow.
Select the Reducer check box to define that the head component of the trunnion ancillary can be positioned on a pipe reducer.
Select the Tee check box to define that the head component of the trunnion ancillary can be positioned on a pipe tee.
Trunnion Types Allowed On
The list of allowed trunnions contains all trunnions that the currently selected trunnion ancillary can be created on.
The list of restricted trunnions allows you to specify the trunnion types that the ancillary cannot be created on.
To restrict an ancillary from being created on a trunnion type, select an item in the list of allowed trunnions and click the right arrow at the side of the list. The item is transferred to the adjacent list. Click the left arrow to reverse the action.
