Apply hidden line in a component by API

[fagmj]

How to apply the "Hidden Lines" option to a component in a drawing view, using the API? I didn't find anything in Programming Help about this.

I was able to achieve this running the command directly:

    Dim oControlDef As ControlDefinition
    Set oControlDef = ThisApplication.CommandManager.ControlDefinitions.Item("DrawingBodyHiddenLinesCtxCmd")
    oControlDef.Execute

Now I wonder how I could change the layer of the already selected lines.

Hi fagmj,

I'm trying to solve this too. How did you select the component to run the command on? The following code doesn't work. 

        public void SetCompOccHiddenLines(int _viewIndex, string _occName, bool _include)
        {
            // Set a reference to the view's referenced model.
            Document _doc = View(_viewIndex).ReferencedDocumentDescriptor.ReferencedDocument;

            // Validate the document type.
            if (!ValidateDocType(DocumentTypeEnum.kAssemblyDocumentObject, _doc)) return;

            // Set a reference to the component definition.
            AssemblyDocument _asmDoc = (AssemblyDocument)_doc;
            AssemblyComponentDefinition _asmCompDef = _asmDoc.ComponentDefinition;

            // Get all leaf occurrences from the assembly model.
            ComponentOccurrencesEnumerator _occEnum = _asmCompDef.Occurrences.AllLeafOccurrences;

            foreach (ComponentOccurrence _occ in _occEnum)
            {
                // Validate this occurrence matches the supplied _occName.
                if (!_occ.Name.ToUpper().Contains(_occName.ToUpper())) continue;

                // Validate the component is both visibile and active.
                if (_occ.Suppressed || !_occ.Visible) continue;

                PartComponentDefinition _definition = _occ.Definition as PartComponentDefinition;
                if (_definition == null) continue;

                ControlDefinition _def =
                       Application.CommandManager.ControlDefinitions["DrawingBodyHiddenLinesCtxCmd"];
                _def.Execute();
            }
        }
