This is an issue that I am dealing with since started using Rhinoceros 6. I use Rhinoceros for creating technical drawings, or documents that may be considered as data-sheets in a simpler way. Since I am much more comfortable with Rhino, I create all my elements like text etc. in it and then export an Illustrator file to continue working on. But exporting to ai deletes all paragraph formatting and set default position to lower left.
On left you can see Rhino attributes for texts, on the right notice little orange squares placed lower left which means all text are aligned left instead of center. And changing font, text, size, or making them bold or italic completely makes it a mess. I searched the settings and forums and couldn’t find a solution. It was not working that way in Rhinoceros 5 and early betas as far as I remember.
