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
