The Selection class is a concept class for selection-related enum classes.
Enumeration of the various selection algorithms.
This algorithm will post-process the SelectionResults to remove items which are obscured by other objects in the scene, and therefore only items that are visible on the screen will be selected.
This algorithm will perform analytic world space selection testing, and will not post-process the SelectionResults based on obscuration. Therefore, items which are not currently visible may still be returned in the SelectionResults.
- enumerator Visual
Enumeration of the various selection granularities.
Use the most efficient selection determination for curves, edges and lines.
Use the most accurate selection determination for curves, edges and lines.
- enumerator General
Enumeration of the various selection levels.
Enumeration of the various selection sorting choices.
Return the owning segment of the selected geometry entities in SelectionResults.
Return the selected geometry entities in SelectionResults.
Return the selected geometry entities and the associated faces, edges and vertices for shells or meshes in SelectionResults.
- enumerator Segment
Do not sort selection results.
Sort selection results according to the screen-space proximity to the selection point. Ties (items with equal proximity) will be further z-sorted. Note that Lines (and edges and all line-like geometry such as circular arcs) and Markers are biased to make them more easily selectable. This biasing is part of the proximity calculation, and it is therefore possible that Lines and Markers are sorted ahead of other geometry that is closer to the selection point.
Proximity sorting is only relevant for SelectByPoint.
Sort selection results from front to back.
Use Proximity sorting for SelectByPoint. Use ZSorting in all other cases.
