Exceptions
ExceptionCondition
ArgumentException The document is a 3d model family. -or- Details can't be drawn in the view. -or- Masking regions and Filled regions can't be created in this document or view. -or- The input curve loops cannot compose a valid boundary, that means: the "curveLoops" collection is empty; or some curve loops intersect with each other; or each curve loop is not closed individually; or each curve loop is not planar; or each curve loop is not in a plane parallel to the view's detail sketch plane; or input curves contain at least one helical curve. -or- Thrown if the viewId is invalid, or the view does not support the detail items creation, or if the boundaries are empty, open, or self-intersecting.
ArgumentNullException A non-optional argument was null
Remarks
View-specific masking regions can be created in models and 2d families. The line style of the boundaries will be set to thin lines by default.
