Repeat or loop

[BrianTFC]

Hi All,

 

I have figured out to combine my three Lisp rputine but it still need works, i need to repeat the last part of the routine until right clicked and i can't figure it out it's driving me nuts. Can some one please help me. Also is there a way to use the the results from the first part of the routine to run the rest of the routine?

 

Thanks, Brian

Hi Brian,

 

You seem to have a good handle on the auto/visual lisp functions. Could you please explain what exactly you are trying to achieve with your program?

 

Regards

I thought I recognised some of that code

Wow... that is old...

Hi,

 

When the lisp routine runs it does the first two parts just fine but when it gets to the last part it only lets me pick one line then ends the command, what i would like to do is pick as many lines that i need to and then right click out of the command. any thoughts.

Hi Lee

 

Yes Lee it does have a part of the PLLEN.lsp routine you wrote along time ago. Thanks to people like you we novice can learn how to write routines that work for what we need done. Many Thanks Lee.

I agree with you! http://www.cadtutor.net/forum/showthread.php?756-offset-multiple-objects

 

Brian, you should post a short notice, if you barrow code from others. People spent their time to offer routines for free, at least leave their names for the posterity.

Hi,

 

I didn't mean to offend anybody. When i was combinding them together i just used the lines that pertained to the function of the lisp routine. Many apolyogies. I will remeber that for the future.

No offense was taken, it was just a friendly word of warning. If you will keep that in your mind for the future, that's good.

Brian, both fuccaro & Lee are right in the leading pack of those who have donated mind blowing amounts of code, expertise and energy to helping others on this site and elsewhere for years now. Presumably you noticed the reference to fuccaro's posted code too? :wink:

[fuccaro]

Thanks Dadgad!

I think we can consider this issue belonging to the past. I just post here a link to a thread about copyright, and now myself I consider this subject closed.
