Maybe if you explained what you want to do you might get some reasonable
suggestions.
CorelDraw is a pretty complex program that can do lots of things.
The Graphics app in Open Office isn't even close to CorelDraw version 3 from
the early 90's.
Zoner Draw may be worth a look...never tried it myself so can't comment.
Some folks here have noted Pixia as a good one and I'm sure there are
others. Perhaps you could check SOS' site for a few hints...
