Exception on AnalyzeInterference

[Anonymous]

Hi,

Just going through this and the below line is causing an exception in the tryAnalizeInterference method. I have put a counter and up to 5 objects no issues however beyond 5 it trips with the following exception.. Any idea what might be causing it?

Exception thrown: 'System.Runtime.InteropServices.COMException' in mscorlib.dll
DebugPluginLocally2.exe Error: 0 : Processing failed. System.Runtime.InteropServices.COMException (0x80004005): Unspecified error (Exception from HRESULT: 0x80004005 (E_FAIL))

I have tested the code below with the latest samples from here and the exception is only relevant to the 'InkJet printer' assembly where it has about 115 component occurences. Tried with other assysand no issues thus far but the other only have less than 21 compoccurs...

So it seems the issue is with the inkjet printer assy, unfortunately i dont have the source code to step in to 😞

private void tryAnalizeInterference(Document doc, NameValueMap map=null)

                {
                        if (item is ComponentOccurrence co) objs.Add(co);
                }

                var adoc = doc as AssemblyDocument;

                if (adoc == null) return;

                if (objs.Count == 0)
                {

The code below was tested against the latest samples from here. It seems only the Inkjet printer assembly is causing the exception. What exactly is causing it?

private void tryAnalizeInterference(Document doc, NameValueMap map=null)

        LogTrace("Processing " + doc.FullFileName);

        try
        {

                var objs = _app.TransientObjects.CreateObjectCollection();

                foreach (var item in doc.SelectSet)
                {
                        if (item is ComponentOccurrence co) objs.Add(co);
                }

                var adoc = doc as AssemblyDocument;

                if (adoc == null) return;

                if (objs.Count == 0)
                {
                        var count = 0;

                        foreach (var item in adoc.ComponentDefinition.Occurrences)
                        {
                                if (item is ComponentOccurrence co)

                                        LogTrace($"count={count},       {co.Name}");
                                        count++;

Hello,

I opened "Inkjet Printer Prototype.iam" and run your last code.

It doesn't cause exception.

The log output was...

Processing <<My working directory>>\Inkjet Printer Prototype\Workspace\Inkjet Printer Prototype.iam

count=1, Main Roller:1
count=2, Cartridge Rail:1
count=3, Cartridge Stop:1

count=5, Main Roller Cap R:1

...Omission...

Is something different with you?

My system is...

* Inventor Pro 2020.1 + Japanese Language Pack

Oh, should I select something before executing the code?

[Anonymous]

yeah, you need to select an assembly file, or perhaps a part file, check my code mate, just finished a bottle of strong wine, so cannot pinpoint, but the issue was only with the Inkjet printer, oh yeah, iam file. down load it from the link i mentioned.

Hi Hideo,

Thanks so much for investigating....

for some reason i didnt get a notification for your replies hence the late response!

All seems to be working well this morning on the same code and same input file however different windows session and inventor session so one of them may have cleared up the issues.

next time i will do those two steps before i sound the alaram.

thanks bud!
