Parameters

PatternName: Type: SystemString
The pattern name.
Boundary: Type: System.Collections.GenericListEntityObject
A list of entities defining the boundary.
HollowBoundary (Optional): Type: System.Collections.GenericListEntityObject
A list of entities defining the boundary that encloses or defines empty or open spaces within an area.
Rotation (Optional): Type: SystemDouble
The hatch rotation in drawing's units (Default value = 0).
Scale (Optional): Type: SystemDouble
The hatch scale in drawing's units (Default value = 1).
ACIColor (Optional): Type: SystemInt16
A number for 0 to 256 corresponding to the AutoCAD Color Index (0 = ByBlock; 256 = ByLayer. Default value = 256).
LayerName (Optional): Type: SystemString
The layer name. If omitted, or layername doesn't exist, the CurrentLayer will be used.
LineTypeName (Optional): Type: SystemString
The layer name. If omitted, or layername doesn't exist, , or layername doesn't exist, the CurrentLineTypeName will be used.

Return Value

Type: EntityObject
The new added Hatch.

Examples

Adds a solid hatch to a closed object. Assuming that in the following drawing:

the ellipse is the entity #0, the circle is the entity #1 and the rectangle is the entity #2 use the following code:

Copy

[C#]

List<EntityObject> Boundary = new List<EntityObject>();
List<EntityObject> BoundaryOutermost = new List<EntityObject>();

Boundary.Add(dxfReaderNETControl1.DXF.Entities[0]);
BoundaryOutermost.Add(dxfReaderNETControl1.DXF.Entities[1]);
BoundaryOutermost.Add(dxfReaderNETControl1.DXF.Entities[2]);

dxfReaderNETControl1.AddHatch("SOLID", Boundary, BoundaryOutermost);

The result is:
