LIST OF LISP COMMANDS CODE

This check can be helpful if your routines depend on the definition of a function from a previously loaded file. The list returned is useful, but can take a while to sort through as it is not in alphabetical order or an order that will make much sense.Īs mentioned previously, you can use the ATOMS-FAMILY function to test for the existence of a symbol, function, or variable by passing in a list of the items you want to see exist. "VLA-GET-SHOWPLOTSTYLES" "VLA-GET-NUMCELLSTYLES" "AI_RETURN" "C:SAVEALL") ("ACTOOLBARDOCKBOTTOM" "ACET-VAR-SETVAR" "ACVIEWPORT4" "AC3IN_1FT" "VLA-ADDBOX" Symbol_list - Optional List of symbols, variables, or functions to search for.Įntering (atoms-family 1) at the Command prompt returns a long list that might look like the following. Valid values are 0 for Symbols or 1 for Strings. This ability to check for the existence of previous definitions is helpful if you want to see which functions are exposed before loading an AutoLISP file.įormat - Determines how the values in the returned list are formated. You can also use the function to check to see if a specific symbol, global variable, and/or function is currently defined or set. The ATOMS-FAMILY (not the Adams Family) function returns a list of all the symbols, global variables, and functions currently defined for use by AutoLISP.

cmpinclude.AutoLISP is one of the oldest and easiest ways of extending AutoCAD, but did you ever wonder what functions are currently defined or which global variables are already set?.
