The tips included in this book come from everyday CAD operators looking to solve problems encountered on a daily basis. This HOT item also contains all new tips and tricks in the book and a disk. CAD Corner Canada also has an upload link where you can share some of your own Autolisp routines and help out others. As AutoCAD users, we have all run into situations where it would be great to reduce repetitive tasks.

If the symbol exists, the argument returns a symbol name otherwise it returns nil. The optional symbol argument is used to check whether each symbol in the symbol list exists in the current editing session. The format argument specifies whether the symbols will be returned as symbols or strings: 0 returns a list of symbols and 1 returns list of symbols converted to strings. This way you can know what symbols have been defined in the drawing session. The atoms-family function returns a list of all the symbols currently defined, called the atom list. They will not be added to the atom-list and will only be retained in memory while the function is executing. Or they are the ones you must supply for the function to work. The optional arguments are the variables that you will want permanently assigned in a drawing session. A variable can be declared exclusive to a given function. All variables in use in a session of AutoCAD are stored in the atom list. Another good clarity practice is to keep the track of the variables you use as symbols and make sure you do not leave them active in AutoCAD if they will impact another routine. This makes a smoother interface between your LISP routine and the main package. Make the routine as easy to use as possible. Use error control such as the iniget and getkword functions.

They automatically insert tabs and spaces where needed to give you added clarity and help you track parentheses. When creating AutoLISP routines, the programmer should keep in mind not only correct syntax, but also a well-structured program that is easy to comprehend, forgiving of mistakes, easy to debug, and easy to edit.
