Lisp help - lts before plot

[M_c3d]

I'm trying to write a lisp to set the lts to 1 before plotting;

(command "_.undefine" "Plot")
(defun C:Plot () (ltscale;1;) (command "_.Plot"))
 
It does the lts part properly, but it says unknown command "PLOT"

Any ideas what I'm doing wrong? or if this is at all possible?

Thanks,

I'm surprised anything about that code works.  Try starting vlide at the command line.  Then paste your code into a new window.  Notice how the sem-colons comment out the code?

There is no ltscale lisp function.  Everything after the first semicolon is ignored.

Try:

(command "_.undefine" "Plot")
(defun C:Plot () 
  (setvar "ltscale" 1) 
  (command "_.Plot")
)

You can only use semi-colons in menu macros.

Lisps aren't my strong point, so I appreciate your help on this.  I'm also surprised any of my previous attempt worked!  It was a modification of a previous lisp.

It works perfectly, I've added in (initdia) to get the plot dialog up

(command "_.undefine" "Plot") (defun C:Plot () (setvar "ltscale" 1)  (initdia) (command "_.Plot") )

Is it possible to add a regenall into it after the "ltscale" 1 to get it to update the display (it plots fine)

Copied your logic and added (Command "regenall") to before the (initdia) and it works perfectly.

Thanks for your help

Glad it worked for you.  I have my own plot redefinition function but it doesn't focus on ltscale. Rather it flags me if any xref needs reloading or is unable to be loaded.  Generally I keep LTSCALE, PSLTSCALE, and MSLTSCALE set to 1 so there is never a need to check them.  Sometimes though, I get annoyed with how picky it is and override my own command redefinition by entering .plot. I always plot to a PDF rather than to an actual printer so there is usually a cycle of plot, review, repeat until all(hopefully) the kinks are out.
