Corel DESIGNER is a vector-based graphics program.
It was originally developed by Micrografx, which was bought by Corel in 2001.
This program was later sold as Corel DESIGNER 9.
There are still a number of users who continue working with version 9.0, because newer versions of the product are based on a modified CorelDRAW rather than the original product.
[1] Corel DESIGNER is effective for the creation of engineering drawings, but also offers many functions for graphic design.
