This is something that I should know but use illustrator export so infrequently, if I did know at one time I have forgotten. And Illustrator just as infrequently.
Let’s say I create an R in Rhino with curves and export it to illustrator. It comes in fine but all the curves are outlined and I want it to be a ‘solid’ black R and not outlined. If I fill it in illustrator the ‘hole’ also fills black. How do I remove that hole in the R so that it is part of the R and not a seperate piece which fills in black?
