Property IsSketchValid

IsSketchValid

Gets a value indicating whether this builder contains sufficient points to show a valid graphical sketch.

Declaration
public virtual bool IsSketchValid { get; }
Property Value
Type Description
Boolean

A value indicating whether this builder contains sufficient points to show a valid graphical sketch.

Remarks

This can be used as an initial lightweight check to see if the current state of a builder produces a non-empty geometry; for example, it may be used to enable or disable functionality in an editing user interface. The exact requirements vary depending on the type of geometry produced by the builder:

  • A MapPointBuilder must contain non-NaN x,y coordinates.
  • A MultipointBuilder must contain at least one valid MapPoint.
  • A PolylineBuilder must contain at least one Part. Each Part it contains must have: at least two valid points, or at least one Segment where IsCurve is true.
  • A PolygonBuilder must contain at least one Part. Each Part it contains must have: at least three valid points, or at least one Segment where IsCurve is true.
  • EnvelopeBuilder must contain non-NaN minimum and maximum x and y values.

Note that this is not equivalent to topological simplicity, which is enforced by Simplify(Geometry) and checked using IsSimple(Geometry). Geometries must be topologically simple to be successfully saved in a geodatabase or used in some service operations.

Does not check the SpatialReference. Returns false if an error occurs.

Prior to v100.8, only one part of a multipart polygon or polyline was required to have the minimum number (2 for a polyline, 3 for a polygon) of points, and only LineSegment instances were supported in builders.

Prior to v100.12, a PolygonBuilder required at least three valid Points in each Part, and at least one part.
