Opened file again, and able to repeat it, two attempts two fails.
I sent off the error report when it happened, I didnt attach the file as its valuable and confidential so need some written assurance it will not leak out into the world. Then I am happy to submit it.
The file features 3D rivet heads in a circular array and this saw V5 freeze twice when attempting this along with rest of fuselage as a three view make2D. Doing it alone it took 40 secs per view. Its repeated rivets Rhino hates when not as block instances and I had to explode these so as to colour them up.
I can send an example of the bits that form a Make2D line created in V5.
If I send an email to you maybe you can reply to it., then I can send the spinner.
I can do so after I have downloaded and run a sim I purchased a year ago , as it requires Steam online and steam wrecked a flight sim with an update no one expected so I need to be sure it doesnt do so again. I have backed up PC and await the go ahead on steam but cant access emails meanwhile else backup is out of date and cannot be then used to recover pc.
