Since your using Cadworx, I assume you want vector software. Logo's for a number of reasons are best done as vector anyway.
Inkscape is free and very capable. It imports most things, but not perfect every time.
Gravit is free but maybe not so great at import.
Illustrator is not free, somewhat costly but most of the world uses it. It is certainly capable. Good import abilities, great if you consider most of the stuff your going to get is probably in an Illustrator format already and it just opens, not imports.
CorelDraw is not free, somewhat costly, capable, and imports well, (import is rarely perfect.) It is my current favorite.
Some cutting software if your using a cutter has design abilities and imports well. Vinly Master and the Flexi series come to mind.
Xara pro has a following, capable and can import.
Affinity Designer is note worthy in its low cost.
