Hello everybody,

Thanks in advance for any help or clue guiding to find a solution.

I am sure next question will be opening a excel file have a look at Getexcel.lsp a good reference with lots of functions.

Also another Denon Deterding, ALx Functions Creator has various excel functions for autocad.
