...Employed early Corel Graphics Suite vector drawing versions rendering them; cut teeth with Micrografx Draw c,1994-98, lightweight & fast though limited editing tools. open source GNU Image Manipulation Program (GIMP) raster good "no cost" Corel substitute though vector best for graphic object editing. I still pine rendering original 1941 CONVAIR B-36 design in pre-1942 "silver bird" USAAF livery though don't relish shelling out buying vector software just to render it alone nor am up to nerve-racking effort doing so, hopefully somebody has or will render it 3-D sparing me the anguish!
