A macro is simply a recording of your keystrokes, or entries. It is not hard to do.
- Go up into your Tools > Macro menu and and make a short program.
- Press “start record” (enter the name of program), then create a cube, or draw a line, or do something like that, even something more complex, and then press “stop recording”.
- Then delete what you created (or press “undo” until gone) and replay the macro.
It is really nice when the NX macros that you use often are added to a tooolbar. Simply press a button to make it go.
There are some programming things where more code is involved. But macros are really quite easy.
