    At the trade shows, all three of the major CMC makers provide classes on the software they use. Wizard and Gunnar have their own proprietary software, and their classes are always full. I don't know if their classes would apply to the commercially-available software programs, but Valiani has provided classes on Corel Draw, because that's the program they recommend for their CMCs.

    Janet, I tried unsuccessfully for seven years to find shortcuts in the CAD learning process. My suggestion is to buy software compatible with your CMC and learn how to use it. No matter what you want to do with the software, you have to learn the fundamentals -- which is what takes the time initially. After that you can progress on our own.

    Mark, do you offer CAD classes at the trade shows?

    One of the reasons that Wizard's CAD class is full is that I take it. Every trade show. Every time. I think I have done it at least 5 times. I listen, I take copious notes, I get home, sit down at the computer, and VOILA! All my notes have turned to Sanskrit!

    I am taking the webinar in May, desperately hoping that someone walking me through it while I am sitting at a computer will finally lodge the information in my brain.

    Maybe I should have my 8 year old grandson take it.....
    If you'd do what I told you the first time, I wouldn't have to be so bossy.

    If my memery serves me correctly you had a problem that would take a image and draw the cutting program. We are going to get the new Wizard 9000 the first week of May and would like to be ready to design without our old pathtrace program.

    Everyone has very good points. CAD is a three letter word in the art industry. Art is a right brained activity while CAD is a left brained activity. When I am speaking about CAD I don't mean 3D shaded programs like SolidWorks ($3000-$8000). I use this to design parts for your CMCs. I mean 2D programs like DoubleCAD (Free at DoubleCAD.com). DeltaCAD will work too.

    CAD is just a electronic version of graph paper. To use CAD for picture framing you need to learn how to draw lines and arcs and how to erase. Yes, you will also need to know how to save your file and create a file, typically DXF, that your CMC software will understand. You do not need to know every bell and whistle in your software. Learning the bells & whistles can come later.

    Someone mention splines. Splines are like Baskin-Robbins ice cream - there are more flavors, or types, than you can count. Some programs like Wizards PathTrace and GUNNARs new GMC software understand certain types of splines. Most programs understand a basic type of spline called a Cubic Bezier Spline. If you're interested in the details on this animal just search Google and Wikipedia. This is cutting edge for the CMC business. This is a topic for a whole other thread.

    I can provide on site CAD training. (Please don't kick this thread to the Commercial Post just because wrote that.) I am contemplating a CAD class at a trade show but I think that this type of training is more one-on-one hands on training. Educationally the trade show class is excellent to introduce you to the possibilities of using CAD but it not the forum for teaching you how to use CAD.

    One other topic that you need to know about is "Tangent". What makes a line tangent to an arc, or an arc tangent to another arc. Again, search Google and Wiki for this answer - it bigger than this post.

    Once you can draw a line, an arc, trim, and erase, make one item tangent to another, save, and export a DXF files - You can draw and cut anything. The rest is just icing on the cake.

    P.S. a laser does kick a$$ over a CMC for detailed cutting.

    Thank you for that information; I'll be trying out DoubleCAD soon! It's been a long time since I took CAD in college (as a design major, we worked more in the Adobe suite, so I'm more familiar with Illustrator than anything) but find that PathTrace doesn't have the tools I need to really experiment.

    The right-brain/left-brain comparison might be an issue with me as well, but I have no problem creating paths using Adobe Bezier pen tools, maybe because it's as though I'm technically drawing them out.

    I look forward to trying out DoubleCAD. Thanks again for posting that out. Between Corel and Adobe in what I do, Adobe's more practical; the DoubleCAD will be an affordable (free) alternative.
