Pre a2k, I was able to have people logon with a specific user account so all drawings open as read only. I then had lisp open every cad file with "/b <script>"....everything worked out great. Acad post-14 won't do this anymore. There's an extra prompt for "Read Only BS" which script files can't handle. I've tried every suggestion on this board to no avail. I'm beginning to think that the vlisp "(vla-Open acadDocuments aDwgFile :vlax-True)" can't open a drawing with a /b switch. In the above example where aDwgFile = (strcat MyDwg " /b <script>") Is there a way to open a drawing as a read-only and run a script? If there is a solution, I know this group will have an answer. Thanks in advance.
