FamilyItemFactory.NewLinearDimension

Description:
Generate a new linear dimension object using the default dimension type.
Remarks:
The currently user set default style is used for the created dimension.
Overloads (2):
NewLinearDimension
NewLinearDimension(View,Line,ReferenceArray)
NewLinearDimension(View,Line,ReferenceArray,DimensionType) 
public Dimension NewLinearDimension(
	View view,
	Line line,
	ReferenceArray references
)
  • View
    view
    The view in which the dimension is to be visible.
  • Line
    line
    The extension line of the dimension.
  • ReferenceArray
    references
    An array of geometric references to which the dimension is to be bound. You must supply at least two references, and all references supplied must be parallel to each other and perpendicular to the extension line.
Return Value Dimension If creation was successful the new linear dimension is returned, otherwise an exception with failure information will be thrown.
