Really?
The OP shows where it could be of importance to know whether the text will be cut correctly or split up in pieces, and where a quick look in wireframe/outline mode would be an easy way to find out.
Regarding "hidden objects" that was mentioned, I have noticed over the years that files created in Illustrator have a tendency to have invisible/hidden objects and empty text blocks (when the user has accidentally clicked or dragged with the text tool) on and outside the drawing area, and the wireframe mode in Draw is also here a quick and easy way to find and get rid of them, even if they should be behind text.
And (FWIW) in addition to the wireframe mode, Ctrl+clicking a layer's color bar in CorelDRAW's Object docker will make that particular layer show in colored wireframe mode. Very useful.
Maybe there's something similar in Illustrator now, but I have not been able to find it in my old CS5.
Yes, really.
In the opening post, he asks one question, which was answered using various methods. He asked to see
BEHIND the letters, not how they're created.
Then, he later shows and admits it's another case of needing to know. Totally different, because that was not created in either/or program, so he's introducing a completely new request.
You, yourself also mentioned about things appearing, but they were all created by committing mistakes, which I already said, he or someone is doing something(s) wrong.
For us the hidden mistakes are usually created by another person's designer, who does things their way, by using 1,200 masks or the big one is fonts, we don't have.
Many ways to make things look like they'll work, but normally only sign designers/computer operators will do it to your liking. A designer who's background is doing things for websites, magazines and other non-sign related formats use their programs how they see fit. Then, you have the weekend warrior designers who do everything in raster and just call it a vectorized file.
Oh yeah, don't forget little Sally, the owner's niece who was good at etch-a-sketch and got an 'A' in art class.
