My First Plug-in - get group names from assembly file

[Anonymous]

Hi All

I have followed the My First Plug-in Training  http://usa.autodesk.com/adsk/servlet/index?siteID=123112&id=17332618

This plugin allows the user to group components in an assembly file and toggle the visibility on and off.

Currently it only allows for one group so I would like to expand on this by creating multiple groups.

I would like the group names to be variable which is fine but my problem is recalling the group names from the selected assembly document.

Heres the code that adds the item(s) to the group and underlined is where i have modified it.

string selectedGroup;


public void AddOrRemoveFromGroup(bool add)
        {
           
            AssemblyDocument asmDoc = default(AssemblyDocument);
            asmDoc = (AssemblyDocument)_invApp.ActiveDocument;

            if (asmDoc.SelectSet.Count == 0)
            {
                System.Windows.MessageBox.Show("Need to select a Part or Sub Assembly");
                return;
            }

            SelectSet selSet = default(SelectSet);
            selSet = asmDoc.SelectSet;

            try
            {
                ComponentOccurrence compOcc = default(ComponentOccurrence);
                object obj = null;
                foreach (object obj_loopVariable in selSet)
                {
                    obj = obj_loopVariable;
                    compOcc = (ComponentOccurrence)obj;
                    System.Diagnostics.Debug.Print(compOcc.Name);

                    AttributeSets attbSets = compOcc.AttributeSets;

                    if (add)
                    {
                        // Add the attributes to the ComponentOccurrence

                        if (!attbSets.NameIsUsed["myPartGroup"])
                        {
                            AttributeSet attbSet = attbSets.Add("myPartGroup");

                            Inventor.Attribute attb = attbSet.Add(selectedGroup, ValueTypeEnum.kStringType, "Group1");

                        }
                    }
                    else
                    {
                        // Delete the attributes to the ComponentOccurrence
                        if (attbSets.NameIsUsed["myPartGroup"])
                        {
                            attbSets["myPartGroup"].Delete();
                        }
                    }
                }
            }
            catch (Exception ex)
            {
                System.Windows.MessageBox.Show("Is the selected item a Component?");
                System.Windows.MessageBox.Show(ex.ToString());
                return;
            }
        }

What i would like is to loop through the active assembly document and get the group names already existing.

Any help would be greatfully received.

Thanks

Chris.

Inventor API Help contains the “Traverse an Assembly API Sample” that shows how to recursively traverse an assembly and access all leaf node components and subassemblies to analyze their attributes.

In some situations it is convenient to use the ComponentOccurrences.AllLeafOccurrences property.  It returns the ComponentOccurrencesEnumerator collection that contains the references to all unique leaf occurrences in the assembly document where you get the ComponentOccurrences collection.

Hope it helps

Thanks I will give it a go. I am a real novice so will try and work it out.

Thanks again.
