Exceptions
ExceptionCondition
ArgumentException When setting this property: The patternId must either be InvalidElementId or represent a valid FillPatternElement. -or- When setting this property: The patternId must be a 'Drafting' pattern. -or- When setting this property: In a family the patternId can not be a solid fill pattern if the 'IsMasking' property is false.
ArgumentNullException When setting this property: A non-optional argument was null
Remarks
The FillPattern used for a background pattern must have a 'Drafting' target. This applies to both project and family elements. In addition, when the FilledRegionAttributes element is in a family, the pattern cannot be the solid fill pattern unless the 'IsMasking' property is set to true. InvalidElementId is used when there is no background pattern
