A place where I work does not have corel draw on my machine. So I download inkscape. I have found to to be very good. While I like corel better, inkscape is a viable alternative in a pinch.
It took a bit to get used to, but now I can use it almost as well as I can corel draw. It lacks some of the cool shortcuts corel draw has like centering.
One thing I do like is it can import many illustrator or corel draw files. So if you have an older version of corel draw and can't bring in an ai file. This might be your ticket.
Anyways,
Out out!
