VVC: internal error - WC:Internal error Autocad 2015

[Grant]

Found this a problem with Acad 2015 - if you get this error go into your code and look for 'mapcar' then within that look for 'command' and change to 'command-s'

 

(if plst

(progn

(mapcar

'(lambda (X)

;turn layer on

(if (> (cadr X) 0)

(command-s "._-LAYER" "_ON" (car X) "")

);i

);l

plst

);m

);p

 

Hope this helps some people as it was hard to find
