add custom iProperties to each component with c# add-in

[Anonymous]

Hi

i have a simple application that runs as an add-in in Inventor, that i use to change the visibility of several parts in an assembly document.

it changes the visibility of all the selected parts and components.

its code is like this:

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);
                            compOcc.Visible = !compOcc.Visible;
                            //add costum iproperties for each selected component
                        }
                    }
                    catch (Exception ex)
                    {
                        return;
                    }

i would like to add a costume i properties to each component,  can anybody suggest me how to do that?

Give this a convert from VB.Net and then check it out.

                        End If
                    End If
                Else 'is emtpy - overwrite command does snot apply
                    custProp.Value = propValue
                    filesEffected += 1
                    eventLog += vbCrLf & "Modified custom property: " & propName & ":  " & propValue
                    Return True
                End If
            End If
            Return False
        Catch ex As Exception
            'if property fails to write such as user does not check out or allow file to save, then retun without error.
            MsgBox("Can not write custom property: " & propName)
            Return False
        End Try
    End Function

btw eventLog and filesEffected are a public shared string and integer values I use when running this program as part of a much larger system.  It reports possible errors for the user to read about.  You can omit that feature, or change it up as you see fit.

thank you @JamieVJohnson2 

but I think this will add the custom property to active document if it's not added already, or change its value if it is present.  am i right? or I am misunderstanding something here

I am about to add the property to each one of the components that is selected by the user (or in some cases all component in the active document_that is not my question now) in an assembly document.

@Anonymous ,

Try below C# code to add custom iProperties to occurrence.

public void occ_customipropertty(AssemblyDocument asmDoc)
        {
            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);
                    compOcc.Visible = !compOcc.Visible;
                    //add costum iproperties for each selected component
                    CreateAndEditCustomProperty("Property Name", "Property value", compOcc.ReferencedDocumentDescriptor.ReferencedDocument);
                }
            }
            catch (Exception ex)
            {
                return;
            }
        }
        public void CreateAndEditCustomProperty(string propName, object propValue, Inventor.Document invDoc)
        { 
            PropertySet propSet = invDoc.PropertySets["Inventor User Defined Properties"];
            Inventor.Property prop;
            try
            {
                prop = propSet[propName];
            }
            catch (Exception e)
            {
                prop = propSet.Add("",propName);                    
            }
            prop.Value = propValue;
            
        }

Thanks and regards,

Just like the other code posted, the routine I posted, requires you to input the desired document for it to do work on.  So it would not be the 'active document' per se, it would be any document you acquire in advance, and then send into it.

my actual problem was to accessing to the referenced document through component occurrence.

that was solved by this line:

compOcc.ReferencedDocumentDescriptor.ReferencedDocument
