GỘP 2 MẪU HATCH LẠI VỚI NHAU
- Mỗi lần bạn sử dụng một mẫu hatch, bạn phải sử dụng 2 hatch chập nhau. Ví dụ như khi bạn sử dụng hatch bê tông cốt thép, bạn phải sử dụng nét chéo (LINE) và nét gạch vỡ (AR-CONC). Làm sao để bạn nối 2 mẫu hatch này lại thành 1 mẫu mới?
- Bạn tạo 1 file mới có tên trùng với tên mẫu hatch mà bạn đặt với đuôi là .pat. Ví dụ: BE_TONG.PAT.
Bạn mở file Acad.pat trong thư mục support ra, tìm đoạn mà cad mô tả về gạch vỡ, copy vào file mới này, tìm đoạn cad mô tả về Line, copy vào tiếp. Save lại, sử dụng lệnh hatch là ok.
- Ví dụ:

Chú ý:cuối file BE_TONG.PAT này phải có một dòng trống.
coppy file be_tong.pat này vào thư mục support trong cad xong vào hatch/custom trong cad để lấy mẫu này
Hoặc có thể dùng lisp tạo hatch sau
đánh drawhatch để tạo sau khi tạo xong thì đánh savehatch
