Looking for help on MultiSelect :(

[NachoShaw]

Hi

Please please can someone help or point me in the general direction (NOT API because infor isnt there). Im not asking for much, just a bit of help....

1. I need to be able to select multiple parts in an assembly by clicking them. The parts that are clicked need to stay highlighted so that i can process them in a routine. (i have tried the oSelect Class which is ok but cancels the selection after each clicked item

2. i need to be able to select ALL occurrences of a part in an assembly. If there are 7 occurrences of the same part, i need to select them and add them to a selectset.

In the assembly, i am looking the kLeafAssemblyOccurence which is what i need. i am also looking at doc.SelectSet.SelectMultiple (myObject)

i just cannot get it working and i fear a trip to the wig shop due to pull my own hair out lol.....

Please can anyone give me a general pointer or a bit of help?

Thanks

Nigel

1. Ok I will give you an example and point you to the api under the section Interacting with the User, and the sample Basic Selection Using Interaction Events API Sample.

Here's a sample in C# of the basic pattern I use for interactive selecting.

        private InteractionEvents objInteraction;

        private SelectEvents sle;

        private UserInputEvents uiecc;

        private bool curSelection = false;

        public void StartGetObjects()

        {

            sle = null;

            objInteraction = null;

            objInteraction = appInventor.CommandManager.CreateInteractionEvents();

            sle = objInteraction.SelectEvents;

            sle.ResetSelections();

            sle.ClearSelectionFilter();

            sle.SingleSelectEnabled = false;

            sle.AddSelectionFilter(SelectionFilterEnum.kAssemblyOccurrenceFilter);

            objInteraction.StatusBarText = "Select Components";

            //objInteraction.SetCursor(CursorTypeEnum.kCursorBuiltInSelectArrow);

            curSelection = true;

            pckAdd.btnDonePick.OnExecute += new ButtonDefinitionSink_OnExecuteEventHandler(btnDonePick_OnExecute);

            sle.OnSelect += new SelectEventsSink_OnSelectEventHandler(sle_OnSelect);

            sle.OnUnSelect += new SelectEventsSink_OnUnSelectEventHandler(sle_OnUnSelect);

            objInteraction.Start();

        }

        private void sle_OnUnSelect(ObjectsEnumerator UnSelectedEntities, SelectionDeviceEnum SelectionDevice,

    Inventor.Point ModelPosition, Point2d ViewPosition, Inventor.View View)

        {

            if(curSelection)

            {

            //Can remove selected entities from an ObjectCollection or list

            }

        }

        private void sle_OnSelect(ObjectsEnumerator JustSelectedEntities, SelectionDeviceEnum SelectionDevice,

            Inventor.Point ModelPosition, Point2d ViewPosition, Inventor.View View)

        {

            if(curSelection)

            {

            //Can add selected entities to an ObjectCollection or list

            }

        }

First set object filters/options and subscribe to the events on selecting and unselecting. Start the interactive selection session, Save/Remove objects as they are selected. The variable curSelection is true while I'm in selection mode. I have a button that sets that value to false and stops the selection process.

Or when I don't need it to be interactive, I use the Document.SelectSet object and have to workflow of the command be the objects must be preselected.

A select set doesn't need to be used to hold a collection of objects. Use an ObjectCollection. See TransientObjects.CreateObjectCollection(). 

2. Just loop through all the occurences in an assembly testing to see if they are the part you want and if so add them to a list or ObjectCollection.

Hi

Thanks for your reply. I'm programming in .net and testing routines in vba. I'll see if I can convert from C# to .net. Regarding the api, when I search collection, I get no results. I found the simple sielection sample and I'll see if I can expand on that. Up until now, I cannot get a selected multiple set that remains highlighted but perseverance is one of my strong points lol



Thanks

Are you using VB.NET, if so you can try using a C# to VB converter to get you halfway there.

What version of Inventor are you using. In the 2013 API help the sample is under Sample Programs > Parts > General > Basic Selection Using Interaction Events.

Also if you look up the InteractionEvents Object it has a link to the sample on it.

Hi

Yes i am using vb.net

i'll update as i progress

thanks

Hi

most of it converted and i understand a lot of it however, i am erroring on parts. it looks like a button is created but i cannot see what function it calls.

pckAdd.btnDonePick.OnExecute += New ButtonDefinitionSink_OnExecuteEventHandler(btnDonePick_OnExecute)

sle.OnSelect += New SelectEventsSink_OnSelectEventHandler(sle_OnSelect)
sle.OnUnSelect += New SelectEventsSink_OnUnSelectEventHandler(sle_OnUnSelect)

Also, if i try and change these to Sub routines, i get errors

Private  sub sle_OnUnSelect(ObjectsEnumerator Property SelectionDevice,() As UnSelectedEntities,SelectionDeviceEnum
        End Sub
 
        Private sle_OnSelect(ObjectsEnumerator Property SelectionDevice,() As JustSelectedEntities,SelectionDeviceEnum
        End Sub

Thanks

I have a button created else where that the command temporarily uses. It's a Done button the user can pick to signal when they are done selecting.

When the button is clicked it stops the interaction events, turns off the selecting flag, and calls the method that does the work passing the selected objects, and other clean up.

The two select event handlers should have the signature of

        Private Sub sle_OnUnSelect(UnSelectedEntities As ObjectsEnumerator, SelectionDevice As SelectionDeviceEnum, ModelPosition As Inventor.Point,ViewPosition As Point2d,View As Inventor.View)

            If curSelection

            End If

        End Sub

        Private Sub sle_OnSelect(JustSelectedEntities As ObjectsEnumerator, SelectionDevice As SelectionDeviceEnum,ModelPosition As Inventor.Point,ViewPosition As Point2d,View As Inventor.View)

            If curSelection

            End If

        End Sub

Hi

Thanks for that. I have converted it and it al works quietly nicely 🙂

Would you be able to give me a little extra pointer on how to pass the collection of parts to a function to run a few custom updates? It's just the looping of each part in the collection that I am struggling with. I am using Component Occurence. I can run the routine I have with a selected part, I can't quite get the collected selection set to do the same thing


Thanks for your help 🙂

What does the signature of the function you're calling to do work on the parts look like? Ideally you would change it to accept the collection of parts you have picked. Instead of the SelectionSet you use the Collection of Parts.

What type of collection are you using?

[NachoShaw]

Hi

Thanks for your reply. My function is a simple routine to split 1 part from another (where i place one into another). everything processed is a simple rectangle part (think plywood because thats what it is lol).

My intention is to select all of the parts that need to be split in a single process and once selected, run the routine to split the tool part. this is a single part that splits. the routine works fine with a single selection of part then tool but i cannot get the selected collection to do the same..

does that make sense lol?

Thanks

Hi

I am using your code to make the selection and I'm adding to a SelectSet.MultipleSelect. Not entirely sure how to make a collection instead and process it. 🙂


Thanks

You need to have a collection to add/remove items to as they are selected in the Select events.

One way to do is like this.

Dim objSelectSet as ObjectCollection = appInventor.TransientObject.CreateObjectCollection()

Private Sub sle_OnUnSelect(UnSelectedEntities As ObjectsEnumerator,SelectionDevice As SelectionDeviceEnum, ModelPosition As Inventor.Point,ViewPosition As Point2d,View As Inventor.View)

   If curSelection

      'Remove Object from Collection

      If UnSelectedEntities.Count > 0 Then

         For Each obj As Object In UnselectedEntities

            objSelectSet.Remove(obj)

         Next

      End If

   End If

End Sub

Private Sub sle_OnSelect(JustSelectedEntities As ObjectsEnumerator,SelectionDevice As SelectionDeviceEnum,ModelPosition As Inventor.Point,ViewPosition As Point2d,View As Inventor.View)

   If curSelection

      'Add Objects to Collection

      If JustSelectedEntities.Count > 0 Then

         For Each obj As Object In JustSelectedEntities

            objSelectSet.Add(obj)

         Next

      End If

   End If

End Sub

Then pass the objCollection object to whatever function needs the collection.

Hi rjay75

Thank you so must for your code 

I still have problem with 

pckAdd.btnDonePick.OnExecute += new ButtonDefinitionSink_OnExecuteEventHandler(btnDonePick_OnExecute);

            sle.OnSelect += new SelectEventsSink_OnSelectEventHandler(sle_OnSelect);

            sle.OnUnSelect += new SelectEventsSink_OnUnSelectEventHandler(sle_OnUnSelect);

As you said, you will need a button to Done the Select Process. Can you share which code in that button
