I've been using TurboCad Deluxe for about 7 months. As a recently retired computer systems engineer, I am used to learning new software applications and evaluating software. I was a complete CAD novice when I started. By using their tutorial/training guide I was able to get a working knowledge, enough to begin the design on my current project. (See my thread "Greg's French 75 mm Field Artillery Model"). But I found the training less than satisfactory and the software difficult to use. TurboCAD Deluxe is the low-end product, several times the tutorial directed me to do something, it didn't work, and after checking the online reference manual, found the functionality in question was only in the much more expensive Platinum editions. Good news: they have pretty good customer support, helping with a problem I had when upgrading to Windows10, Bad news: you'll probably need that support, TurboCAD has a very complex user interface and mediocre documentation.
For the past 3 weeks, I've been test-driving Autodesk's Fusion 360. This seems to be an excellent product with a very good online tutorial. It is not an intro-level package, it is the full 3D CAD with more functionality than I'll need, yet their interface is much cleaner. It is supposed to be free for non-commercial users, I'll find out in a week when my trial expires.
I will probably switch over from TurboCAD as soon as I see how to make drawings from solid models.
