SelectionOptionsControl

class HPS.SelectionOptionsControl : HPS.Control

The HPS.SelectionOptionsControl class is a smart pointer that is tied to a database object. It is used to set selection related options on a HPS.WindowKey. Options include the selection algorithm, granularity, internal limit, related limit, level, proximity, and sorting. Default values for the various fields of HPS.SelectionOptionsControl can be found here.

HPS.SelectionOptionsControl SetInternalLimit (ulong in_limit)

HPS.SelectionOptionsControl SetLevel (HPS.Selection.Level in_level)

Sets the level at which selection will occur.

Default value

Param in_level:The level at which selection will occur. Return:A reference to this SelectionOptionsControl.

HPS.SelectionOptionsControl SetProximity (float in_proximity)

Sets the selection proximity in centimeters or object-relative-units (ORU), depending on the selection-routine being utilized. The selection proximity augments point-based or shell-based selections by also factoring in the area surrounding the selection-point or selection-shell. For HPS.SelectionControl.SelectByPoint, this specifies the radius in centimeters around the selection within which objects will be returned as selected. The value must be positive. For HPS.SelectionControl.SelectByShell, this specifies a distance in object-relative-units that determines whether a selection is performed. A positive proximity value will cause the selection algorithm to perform a selection when the distance between the two bodies is <= proximity, which means the bodies do not have to be touching in order for Visualize to perform a selection. If the proximity == 0, the bodies must be coincident or penetrating for a selection to occur. If proximity < 0, the shells must penetrate each other by at least that amount before a selection is performed. Selection proximity is not relevant for other selection types. When using HPS.SelectionControl.SelectByShell, false positives or negatives for selection may occur if the proximity and/or selection shells meet any of the following criteria:

• The absolute value of a negative proximity is much larger than the actual intersection of the shells. An example would be a shell that represents a thin plate or a thinly-walled tube, and the specified proximity is larger than the thickness of the plate or tube.

• Selection shells (“probes”) have vertices with complex intersections

• Selection shells (“probes”) have concavities, especially multiple adjacent concavities.

Collision detection proximity

Param in_proximity:  The radius around the selection within which objects will be returned as selected. Return:A reference to this SelectionOptionsKit.

HPS.SelectionOptionsControl SetRelatedLimit (ulong in_limit)

Sets the related selection limit. The related selection limit is the maximum number of items that will be returned as selected when performing a selection. A related selection limit of 0 would result in only the first item getting returned. If the value is greater than 0, this indicates the number of additional items beyond the first to return. The order of these additional items will depend on whether sorting is enabled (see SetSorting()).

Default value

SetSorting(Selection.Sorting)

Param in_limit:Limit on the number of items that will be returned as selected when performing a selection. Return:A reference to this SelectionOptionsControl.

HPS.SelectionOptionsControl SetSorting (bool in_sorting)

Sets whether to sort selection results. This is only relevant if the related selection limit is greater than 0 (see SetRelatedLimit). Sorting works on an entity level. Subentity components like edges, vertices and faces are not sorted.

Deprecated:

This function exists for compatibility and SetSorting(Selection.Sorting) should be preferred in general usage.

See also

Default value

Param in_sorting:  Whether to sort selection results. A value of true is equivalent to passing Selection.Sorting.Default to SetSorting(Selection.Sorting), and a value of false is equivalent to passing Selection.Sorting.Off to SetSorting(Selection.Sorting). Return:A reference to this SelectionOptionsControl.

HPS.SelectionOptionsControl SetSorting (HPS.Selection.Sorting in_sorting)

Sets how selection results will be sorted. This is only relevant if the related selection limit is greater than 0 (see SetRelatedLimit()). Sorting works on an entity level. Subentity components like edges, vertices, and faces are not sorted. This option has no effect on SelectByShell. For SelectByPoint, all values of the Selection.Sorting enum apply. Selection.Sorting.Default is an alias for Selection.Sorting.Proximity. For all other selection types, Selection.Sorting.Proximity does not apply. Selection.Sorting.Default is an alias for Selection.Sorting.ZSorting.
