Parameters

Type	Name	Description
GeoObjectList	TheObjects	The objects (curves) that build the shape
Plane	plane	The plane, in which the objects reside
GeoPoint2D	innerPoint	the inner point which acts as a seed to define the shape
System.Double	maxGap	The maiximum allowable gap between curves to still consider them as connected.
ConstrHatchInside.HatchMode	mode	The mode, ConstrHatchInside.HatchMode

Returns

Type	Description
CompoundShape	The shape or null, if no appropriate shape found

System.Boolean	connected	True: the curves are already connected (faster performance), false: the curves may overlap or intersect
System.Boolean	excludeHoles	True: exclude all holes that are inside the outer shape, false: return only the outer shape
System.Double	maxGap	Maximum gap between curves
Plane	plane	The common plane and the location of the shape in 3d space

Returns

Type	Description
