Sau khi tôi chia sẻ code lisp cắt dim trong autocad, thì bây giờ tôi sẽ chia sẻ cho các bạn lisp nối dim trong cad, khi thiết kế đôi lúc chúng ta cần phải nối các dim lại với nhau thành một, ví dụ 2 kích thước 45 ta muốn nói thì 90 thì sử dụng lisp này

Lisp nối dim trong cad join dimension

Lisp nối dim trong cad hay còn gọi là nối kích thước lại với nhau, có nghĩa là lisp này sử dụng để nối cách kích thước cạnh nhau lại thành một kích thước

Cách sử dụng lisp nối dim trong cad

JD => enter => Click chọn dim thứ 1 => Click chọn dim thứ 2 => Xem thành quả

3 thoughts on “Lisp nối dim trong cad join dimension

    1. Nối nhiều dim là sao bạn, có phải click chuột chọn tốt cả các dim rồi enter là nó sẽ nối tất cả lại đúng ko, ok, nếu đúng thì ad viết code cho

      1. đúng rồi đó ad, quét chọn (click chọn thì lâu quá) các dim nó sẽ nối lại làm 1 đó. (thủ công là quét xóa rồi dim lại khá mất thời gian)
