select 1 occurrence from multiple

[Burnit87]

i'm need some help with selecting 1 part from multi select

im building a dxf generator and i can select an entire assembly and it just fishes out the sheet metal, but when i select the same part a couple of times it wil do it  multiple times and thats just a wast of time

so what im basicly looking for is the code that does the opposite of select all occurrences,

so i got a bunch selected and i just want 1 of each parts so part1 1 time , part2 1 time and so on...

tried the ComponentOccurrencesEnumerator, but cant get it to work in a selectset ( so i can count how many times i selected part1)

any ideas someone?

would me very appreciated!!

thanks in advance

I'm not sure how to solve your issue, but I believe there is a free add-in available on the app exchange to accomplish this already.

I'm not positive this is what you want, but check this out. It allows you to select some occurences rather than all.

ok i tell step by step what i want it to do

- first ill set my selection to part priority

- then select complete assembly

- check for double selection

- take sheet metal parts

- run t he dxf genereator for

and the double selection part is where im having troubles, cause if a part is selected 6 times the dxf generator will unfold it 6 times and export it 6 times, wich costs a lot of time, if you got muliple  patterns, and i dont want to hand pick every component.

so basicly i want it to check if a part is being selected multiple occurrences and then deselect all but one.

this is how far i've got, it works sort of but it now keeps de-selecting everything that had more then one selection, im looking for a way to update my selectset

'check if the same part is selected multiple times

ForEach prtDocOcc As ComponentOccurrence In SelSet

ForEach prtDocOcc2 As ComponentOccurrence In SelSet

If prtDocOcc.Definition.Document.fullfileName = prtDocOcc2.Definition.Document.fullfileName Then

If prtDocOcc.Name <> prtDocOcc2.Name Then

SelSet.Remove(prtDocOcc2)

'update selectset or it will de-selecting everything that had more then 1 occ selected

EndIf

EndIf

Next

Next

The code on that link I sent you should allow you to select the single occurrence from the get go. Is that not acceptable for what you want to do?

**** missed it,

been searching al day for a solution but i fixed it

thank you a whole lot

redo:

'check if the same part is selected multiple times

ForEach prtDocOcc AsComponentOccurrenceIn SelSet

ForEach prtDocOcc2 AsComponentOccurrenceIn SelSet

If prtDocOcc.Definition.Document.fullfileName = prtDocOcc2.Definition.Document.fullfileName Then

If prtDocOcc.Name <> prtDocOcc2.Name Then

SelSet.Remove(prtDocOcc2)

GoTo redo

EndIf

EndIf

Next

ran into anthoter problem, when you have  multiple subassemblies you'll need an extra if

redo:

'check if the same part is selected multiple times

ForEach prtDocOcc AsComponentOccurrenceIn SelSet

ForEach prtDocOcc2 AsComponentOccurrenceIn SelSet

If prtDocOcc.Definition.Document.fullfileName = prtDocOcc2.Definition.Document.fullfileName Then

If prtDocOcc.Name <> prtDocOcc2.Name Then

SelSet.Remove(prtDocOcc2)

GoTo redo

ElseIf prtDocOcc.Name = prtDocOcc2.Name Then

Try

If prtDocOcc.ParentOccurrence.Name <> prtDocOcc2.ParentOccurrence.Name Then

SelSet.Remove(prtDocOcc2)

GoTo redo

EndIf

Catch ex AsException

EndTry

EndIf

EndIf

Next

and worked out another solution for big assemblies, cause the current loop takes 3 to 4 times as long

'check if the same part is selected multiple times

Dim firstLoopCounter AsInteger = 1

Dim secondLoopCounter AsInteger = 1

Dim toRemove AsNewCollection

ForEach prtDocOcc AsComponentOccurrenceIn SelSet

secondLoopCounter = 1

ForEach prtDocOcc2 AsComponentOccurrenceIn SelSet

If secondLoopCounter > firstLoopCounter Then

If prtDocOcc.Definition.Document.fullfileName = prtDocOcc2.Definition.Document.fullfileName Then

If prtDocOcc.Name <> prtDocOcc2.Name Then

toRemove.Add(prtDocOcc2)

ElseIf prtDocOcc.Name = prtDocOcc2.Name Then

Try

If prtDocOcc.ParentOccurrence.Name <> prtDocOcc2.ParentOccurrence.Name Then

toRemove.Add(prtDocOcc2)

EndIf

Catch ex AsException

EndTry

EndIf

EndIf

EndIf

secondLoopCounter = secondLoopCounter + 1

Next

firstLoopCounter = firstLoopCounter + 1

Next

ForEach prtDocToRemove AsComponentOccurrenceIn toRemove

SelSet.Remove(prtDocToRemove)

Next
