The CPlane is the plane you create geometry on, and the TPlane is the plane the geometry is machined on. For most 3 axis work and/or indexer work, the two are generally the same: Top/Front/RSide etc. and don't require any modifications or actions to change. If you're doing multi-axis work, it allows you to define TPlanes independant of the CPlane, which lets you machine at angles. You can create planes (C and T) using several methods including solid faces, geometry, existing planes, and even existing views, or rotating the planes by a user defined angle. (If you have manually or otherwise rotated your part to a certain view, you can save that view and assign a TPlane and/or CPlane to it)
E-Stop, I kind of lernt the same way you did. I was several years into it before I ever saw a book or went to a class. It was just me and the help files, which I found to be lacking some basic fundamentals. Chances are you'll be able to find other ways of doing things you need to do. If there's some issues you're having, bring them up, maybe we can find easier/better ways of doing it. Do you have VBS? (v9.1 or later)
