Slanted Column: Unable to determine slanted column end cut plane.

Unable to determine slanted column end cut plane.

This error is received when adding a slanted column.  Can anybody provide some hints on how to solve.

Line line = ApplicationCreator.NewLineBound(insertPoint[0], insertPoint[1]);

FamilyInstance instance = DocumentCreator.NewFamilyInstance(line, trimMaterialType, level, StructuralType.Column);

Parameter param = instance.get_Parameter(BuiltInParameter.SLANTED_COLUMN_TYPE_PARAM);

param.SetParameter(SlantedOrVerticalColumnType.CT_EndPoint);

SetParameter(instance, BuiltInParameter.SLANTED_COLUMN_TOP_CUT_STYLE, ColumnAttachmentCutStyle.CutColumn);

SetParameter(instance, BuiltInParameter.SLANTED_COLUMN_BASE_CUT_STYLE, ColumnAttachmentCutStyle.CutColumn);

The possible reason is that the column cannot be created successfully. You can remove the last two lines to test if the code can create a slanted column. If removing cannot create the slanted column, then the issue is the code to create the column is not right. If removing code can create the slanted column, you can add a doc.Regenerate() after this line. SetParameter(instance, BuiltInParameter.SLANTED_COLUMN_TOP_CUT_STYLE, ColumnAttachmentCutStyle.CutColumn); Hope this helps.
