SnapDetail Class
A SnapDetail is generated from the result of a snap request. In addition to the HitDetail about the reason the element was picked, it holds the exact point on the element from the snapping logic, plus additional information that varies with the type of element and snap mode.

Inherited properties
Name | Type | Inherited from | Description |
---|---|---|---|
distFraction Accessor Inherited ReadOnly | number | HitDetail | The distance in view coordinates between the hit and the near plane. |
distXY Accessor Inherited ReadOnly | number | HitDetail | The xy distance to the hit in view coordinates. |
geometryClass Accessor Inherited ReadOnly | undefined | GeometryClass | HitDetail | The class of the hit geometry. |
hitPoint Accessor Inherited ReadOnly | Point3d | HitDetail | The approximate location in world coordinates on the geometry identified by this HitDetail. |
hitSource Accessor Inherited ReadOnly | HitSource | HitDetail | The procedure that requested the locate operation. |
iModel Accessor Inherited ReadOnly | IModelConnection | HitDetail | The IModelConnection from which the hit originated. In some cases this may not be the same as the iModel associated with the Viewport - for example, if a TiledGraphicsProvider is used to display graphics from a different iModel in the viewport. This HitDetail's element, subcategory, and model Ids are defined in the context of this IModelConnection. |
isElementHit Accessor Inherited ReadOnly | boolean | HitDetail | Return whether sourceId is for a persistent element and not a pickable decoration. |
isExternalIModelHit Accessor Inherited ReadOnly | boolean | HitDetail | Returns true if this hit originated from an IModelConnection other than the one associated with the Viewport. |
isMapHit Accessor Inherited ReadOnly | boolean | HitDetail | |
isModelHit Accessor Inherited ReadOnly | boolean | HitDetail | |
modelId Accessor Inherited ReadOnly | undefined | string | HitDetail | The Id of the ModelState from which the hit originated. |
path Accessor Inherited ReadOnly | undefined | HitPath | HitDetail | Describes the path by which the hit was located through a series of attached views. |
priority Accessor Inherited ReadOnly | HitPriority | HitDetail | The hit geometry priority/classification. |
sourceId Accessor Inherited ReadOnly | string | HitDetail | The source of the geometry. This may be a persistent element Id, or a transient Id used for, e.g., pickable decorations. |
subCategoryId Accessor Inherited ReadOnly | undefined | string | HitDetail | The SubCategory to which the hit geometry belongs. |
testPoint Accessor Inherited ReadOnly | Point3d | HitDetail | The point in world coordinates that was used as the initial locate point. |
viewAttachment Accessor Inherited ReadOnly | undefined | ViewAttachmentHitInfo | HitDetail | Information about the ViewAttachment within which the hit geometry resides, if any. |
viewport Accessor Inherited ReadOnly | ScreenViewport | HitDetail | The viewport in which the locate operation was performed. |
