Kemudian ubah pandangan pada auto cad dengan cara klik view pada toolbar:
Sehingga tampilan gambar seperti gambar
Kemudian gambungkan garis satu dengan yang lain supaya menjadi satu kesatuan.
Command: region
Select objects: Specify opposite corner: 10 found
Select objects:
1 loop extracted.
1 Region created.
Extrude gambar

Current wire frame density: ISOLINES=4
Select objects to extrude: 1 found
Select objects to extrude:
Specify height of extrusion or [Direction/Path/Taper angle] <41.0000>: 41
Kemudian lakukan perubahan pandangan lagi dengan menggunakan perintah yang sama yaitu klik view pada toolbar kemudian pilih NW Isometri.
Sehingga tampilan gambar menjadi seperti gambar.
Command: l
LINE Specify first point:
Specify next point or [Undo]:
Specify next point or [Undo]: *Cancel*
Kemudian ubah pandangannya lagi seperti langkah yang tadi yaitu klik view pada toolbar kemudian klik back menjadi seperti gambar
Kemudian buat lingkarannya

Current settings: Mode = TRIM, Radius = 5.0000
Select first object or [Undo/Polyline/Radius/Trim/Multiple]:
Enter fillet radius <5.0000>: r
Requires numeric distance or two points.
Enter fillet radius <5.0000>: 5
Select an edge or [Chain/Radius]:
Lakukan langkah tersebut pada sisi seperti gambar
Untuk yang belakang ubahlah pandangan menjadi SE Isometric
Lakukan pemotongan pada kedua sisinya
Command: _fillet
