Struggling to meet deadline then things going wrong sees my english become a bit shorthand at times.
I cannot justify annual fee of Illustrator for the day or two I might need it for testing per year. maybe an old version off ebay I could find.
Adobe pricing policy, also Autocad Inventor, and Spaceclaim, all assumes one is using the prog a lot and making money at the work. I use a variety of progs and its impossible to pay for them all with subscription and earn enough to afford it. Hate subs type progs with their sole usage and money making assumptions.
My aircraft was drawn and the fuselage side onto which my stencilling all goes is seen in front view, so of course I end up creating it all in front view. That explains why when opened into Affinity Designer I saw nothing. All vinyl cut services were able to see it though, I will ask them how.
Still not sure though why when I open the ai back into Rhino I get long lines running south east from what were simple triangles, such original triangles when exported to a new file and exported as ai, didnt create that glitch.
Its one of those occasions that occurs often where in context of the entire file it misbehaves, copy it out on its own and its ok.
I cannot post the original file here as its very valuable and I will lose all control over it, its marked up strictly copyright but one has control over bureaus as one knows which bureau received it, if I see it in use anywhere I know exactly who to take to court, but anyone can get hold of it on the internet.
I will remember to get it into top view then flatten it. Lucky all bureaus could read it, maybe they had ai !
I have now done the top view flatten approach, export as ai, open that in Affinity Designer (latest version), still see nothing, just a white rectangle.
