Hi Jay, I am using DXF files. It will handle a few other file types but I have not experimented with them yet. Right now I'm learning to use a program called AutoSketch. It works well as long as you know how to use it. I know many people do use CorelDraw. Some others use Inkscape. All of them are new to me so using any of them involves a learning curve which I'm experiencing right now. I'm getting better the more I use it though.
As is the case with anything else....time is the issue for me. Work, plus....I have too many different hobbies I guess. I play with the laser one evening, then the organ the next , then the lathe the next, then flat woodworking the next, then an evening of yard work and other honey do items, then before you know it the whole week is gone. One of these days..........I hope to slow down and spend all day doing whatever I want.
I suppose I need to download Corel and see how I would like using it.
