Inventor 2018 - Problem with Collection / Reusing Selection Set

[MattH_Work]

I use the code below to build a collection

Public Sub Collection_Build()
Dim oSelectSet = oApp.ActiveDocument.SelectSet
     Dim i As Integer
     For i = 1 To oSelectSet.Count
          ColGeneral.Add(oSelectSet.Item(i))
     Next
End Sub

And the code below to 're-select' after processing the selected items (so that I can repeat if necessary)

Public Sub Collection_Rebuild()
     Dim i As Integer
     For i = 1 To ColGeneral.Count
          oApp.ActiveDocument.SelectSet.Select(ColGeneral.Item(i))
     Next
End Sub

I use the code within a drawing with Views, Text, Symbols etc. for move & rotate. The process works perfectly with Inventor 2015, 2016 & 2017.

However in 2018, views will not re-select if they have been rotated. Text & symbols work as expected but views only 're-select' if they have been moved. If a rotation occurs they need to be manually re-selected.

Is there a regression within 2018 that Autodesk can look into

Bump

Now using 2018.1.2 as still the same issue

Can Autodesk confirm if there is a bug / regression in 2018

1. Try using .Clear before the re-select

2. See if .SelectMultiple has the same behavior.

[MattH_Work]

Once I have run my code on the selected item(s) I already use oApp.ActiveDocument.SelectSet.Clear() before calling Collection_Rebuild()

If I move my item(s) the expected result occurs (item is deselected, my code reselects)

If I rotate my item(s), the item renames unselected

The same code (95%) is used for both move & rotate (Clear collection, rebuild collection, Move / Rotate,  oApp.ActiveDocument.SelectSet.Clear(), Collection_Rebuild())

Text & symbols rotate/move and reselct, Views will only 'reselect' themselves when using my move code, not my rotate code)

In 2016 & 2017 the exact same code works as expected for both move & rotate

"Schrodinger's SelectSet" is what I've come to term this problem.

@MrSmithtastic & I have an addin we've been working on for some time:

https://github.com/AlexFielder/MyFirstInventorAddin

Which uses selectSet in the assembly environment to pull iProperties into a dockable window.

In 2018.2 it works as-as. All versions after that it doesn't work.

There's something about using the AssemblyDocument.SelectSet(1) which makes Inventor deselect the selectset if you query the contents or use them elsewhere.

Hey @MattH_Work can you confirm this isn't an issue in 2019?

I think it could be time for an update if that's the case!!

[MattH_Work]

I can confirm, retaining the selection set DOES NOT WORK in 2019.1.2

[MrSmithtastic]

So in the same update patch for both Inventor 2019 and 2018 they've managed to break this!

Let's hope someone at Autodesk actually reads this and it gets patched back quickly. Until then mine and @AlexFielder's add-in is borderline useless!

I'm going to try and roll my update back if possible, definitely not cool!
