Do you know any program (aplication, lisp etc.) to protect all elements in drawing dwg against changing, copying, making new layouts.. everything without clean printing (but not to vector graphic, file) and measuring?. But I don't think about apllications like cadlock, cadvault, whitch need installing program and which does't block making new layouts. I meen sth like functions of acrobat, where I can change rights of file (f. ex. only print without password, but editing and saving as diffrent name with password)
