Also check the message that comes up in the commandline i.e. before you proceed to the problem drawing in draft, put in the commandline:
ALPH LOG /C:\TEMP\DRAFTERROR.TXT OVER
The events preceding the runtime will then be logged in this logfile. Lets see where does it take us!
No, It's not yet solved............But one temporary solution is that this particular zone is having 20 Structures.... I extracted draft for first 12 structures in one view and remaining 18 in another view. Later i combined both the views in Autocad that's it.....!!
If add the 13 th structure in first view it is showing the Same FATAl Error vice versa...........
