Gear Maker:
Hey, thanks. You're right about AP not having a stroke panel equivalent. (Well, there oughta be one! )
My solution: I opened the EPS logo in AD, found the stroke panel (clearly I don't use AD as much as AP), checked the Stroke With Object and scaled the logo down to roughly what I need it to be. Then I copied and pasted it into my AP illustration. Strangely, I can now scale the logo WITH appropriate stroke proportionality in AP, so now I won't have to rasterize it. I still can't choose if I want the stroke to scale or not within AP. But this works for me right now.
I hope Affinity is taking notice that I shouldn't have to open a totally separate app just to be able to scale a vector object the way I need it. They also should include better documentation with the apps.
Thanks, forum people!
