H�nh lập phương mở

- Để tiếp tục mở h�nh lập phương, h�y sử dụng c�ng cụ "Chọn" v� r� chuột. Khi cho c�c mặt tạo th�nh một mặt phẳng, ta sẽ tạo ra một m� h�nh được gọi l� h�nh trải (h�nh khai triển).

- Để mở từng mặt, ấn giữ ph�m Shift v� r� chuột.

- Để mở một (hoặc tất cả c�c mặt) theo bội của 15, ấn giữ ph�m Ctrl (hoặc ph�m Option tr�n m�y Macintosh).

Tạo v� in c�c h�nh mẫu (h�nh trải)

Cabri 3D cho ph�p bạn tạo ra c�c h�nh mẫu (lưới đa diện) từ c�c đa diện được dựng. Sau đ� bạn c� thể in ch�ng ra để từ đ� tạo c�c h�nh mẫu thực bằng giấy hoặc b�a cứng.
Cabri 3D lets you create patterns ("polyhedral nets") from the polyhedra you construct. You can then print these patterns and use them to create real models out of paper or cardboard.
Để c� được một h�nh mẫu như h�nh vẽ tr�n, h�y theo c�c bước sau :
- D�ng c�ng cụ "Chọn", chọn h�nh trải.
- Chọn bảng chọn "T�i liệu", chọn "Trang h�nh trải mới".
Sau đ� in h�nh trải ra v� với k�o cắt v� hồ d�n, bạn c� thể gấp ch�ng lại để tạo ra m� h�nh thực.
