I need help opening a very large rhino file (2.3 GB). I was making a bunch of subD quadmeshes and the file will no longer open in rhino 7. When I try to open the rhino screen is black with a loading wheel on the mouse and stay like that for as long as I have the file open. It eventually turns gray a…

Thanks, that seems to have worked, looking now… @Tommy3 - so far it seems bad here too. I’ll have to send it to the larger brains. @Tommy3 - this did eventually open in V8 - I went off to eat lunch and forgot about it. Might have opened in 7 if I’d done the same. In any case, the blob of SubDs…

Hi Bill - [image] ambrose_bill: Having similar issue here At the very least, the SystemInfo output and a sample file is needed to be able to look into this. -wim

Thanks Wim, I did send the file yesterday using the link earlier in the thread. system info as follows. rescue3dm (analyse) flagged no errors but failed to import. I left it opening overnight and was able to use the file this morning to print from layouts etc… all worked fine I had to close and r…

Hi Bill - [image] ambrose_bill: I did send the file yesterday using the link earlier in the thread. Thanks for that, Bill. I let Rhino run overnight to get audit information but I ended that process now as it was hanging much of my system. I’ve put this on the list for a closer look by a dev…

Thank you Wim, I look forward to getting some sort of feedback eventually, if only so I can adapt my working practices to reflect. Appreciate you coming back to me

FYI I’ve heard back from McNeel Europe who say that the file opening time is unavoidable due to complexity of meshes. They also successfully opened after running overnight. I did run quad re-mesh on the mesh used (there is only one) and reduced it as much as I could w/o losing resolution - they ar…

Hi Bill - [image] ambrose_bill: FYI I’ve heard back from McNeel Europe who say that the file opening time is unavoidable due to complexity of meshes. Clearly, Rhino 7 did something differently… [image] ambrose_bill: How it then arrives at 2GB file I can’t say […] 2.73 GB ;] The Audit…

Thank you Wim, I will also see if I can recreate the file…and establish why/where the sudden jump in file size occurs

I’ve re-created the file from scratch (importing same meshes and re-creating the rest) and the file size is now a far more manageable 424MB. So I am bit perplexed as to what happened there. Would it be helpful to send the revised version for comparison purposes - as I explained they should be broad…

Hi Bill - [image] ambrose_bill: Would it b helpful to send the revised version for comparison purposes […] You can send it over and I’ll add a comment on the YT report. -wim
