For importing the vector files produced by the CorelDRAW vector editor (1.5.2 CorelDRAW), Inkscape can use the open source Python-based UniConvertor utility. On Linux, simply install the package python-uniconvertor from your distribution’s repository, and it will fetch all necessary dependencies. On Windows, a copy of UniConvertor is packaged with Inkscape and uses Inkscape’s own copy of Python, so you don’t need to install anything. Further information and new versions of UniConvertor can be found at http://sk1project.org.
Currently, UniConvertor can handle most of the aspects of CorelDRAW files with the exception of text objects. The specific Corel formats it supports are: CDR (CorelDRAW versions 7 to X4), CDT (CorelDRAW template files), CCX (CorelDRAW Compressed Exchange files), and CMX (CorelDRAW Presentation Exchange files).
