Contours is one of those neat features of Draw that I keep finding uses for. I like how you can apply, say, an outside to a complex group and Corel will give you just one solid shape to work with. Very useful for labels and screen graphics-- and it's another one of those things that takes a lot longer to do in AI.
Hey, if you prefer to try and construct your drawing in CDraw and handoff in AI, you should really take a look at Oberon.com's AI Clipboard macros. It's great. I've got these now as toolbar buttons, that's how much I like them.
Basically, this set of macros extends CorelDraw's usefulness by allowing you to cut and paste via the Adobe clipboard standard back and forth between Draw and AI, ID, and Photoshop. It gives you a choice of AI8, PDF or EPS (or all three) settings. The first time I used it to bring some logo directly into InDesign AS EDITABLE VECTOR PATHS, I was amazed. It really opens up CorelDraw flexibility. Keep in mind that it doesn't support all the 'exotic' attributes that Corel is capable of, but if it can be put into a PDF, it will come through. And even as a handoff, it's a lot more reliable than the AI export filter (from Corel's side) or the CDR import filter (from the AI side).
That macro set (and a whole lot more) is available here:
