  1. Bác cho em xin cái link download với ạ. Em có bản vẽ thằng Đài Loan nó block dạng Minsert nên bó tay không phá được

  2. chào ban! Bạn cho mình hỏi. Bạn có thể cho mình Lisp sửa nhanh đối tượng Attribute mà không chạy 7cad được không? vì mình chạy Block có các đối tượng Như ” +0.450″ thì nó cứ chạy “.45” nên nó mất tính năng. cảm ơn bạn nhiều.

    • Bạn click double vào attribute >>> như lệnh cũ của AutoCAD >>> hộp hội thoại Attribute Edit mở ra

      Tạm thời bạn có thể bỏ 7cad khỏi StartUp rồi mở lại bản vẽ. Lỗi này tớ sẽ sửa sau.
