In the COM API, styles are held by the root document object. In the .NET API, they are located under CivilDocument.Styles, which is an object of type StylesRoot and contains style objects inherited from StyleBase. Getting and setting style attributes for StyleBase objects requires using a GetDisplayStyle*() method rather than a property. Here’s an example from COM VBA:
oAlignmentStyle.ArrowDisplayStyle2d.Visible = False oAlignmentStyle.ArrowDisplayStyle3d.Visible = False ' Display curves using violet. oAlignmentStyle.CurveDisplayStyle2d.color = 200 ' violet oAlignmentStyle.CurveDisplayStyle3d.color = 200 ' violet oAlignmentStyle.CurveDisplayStyle2d.Visible = True oAlignmentStyle.CurveDisplayStyle3d.Visible = True
This is the equivalent code in VB.NET:
oAlignmentStyle.GetDisplayStyleModel(AlignmentDisplayStyleType.Arrow).Visible = False oAlignmentStyle.GetDisplayStylePlan(AlignmentDisplayStyleType.Arrow).Visible = False ' Display curves using violet. oAlignmentStyle.GetDisplayStyleModel(AlignmentDisplayStyleType.Curve).Color = Autodesk.AutoCAD.Colors.Color.FromRgb(191, 0, 255) ' violet oAlignmentStyle.GetDisplayStylePlan(AlignmentDisplayStyleType.Curve).Color = Autodesk.AutoCAD.Colors.Color.FromRgb(191, 0, 255) ' violet oAlignmentStyle.GetDisplayStyleModel(AlignmentDisplayStyleType.Curve).Visible = True oAlignmentStyle.GetDisplayStylePlan(AlignmentDisplayStyleType.Curve).Visible = True
