AutoCAD 3D Modeling Tutorial
📌 The tutorial focuses on creating a 3D model of a combination wrench (kunci kombinasi), specifically detailing the creation of the open-end wrench and the ring wrench parts.
📐 The open-end wrench handle's initial guide line is drawn with a length of 140 units, incorporating an initial helper line at 20 units length and an angle of 17°.
⚙️ The modeling process heavily utilizes Ellipse, Offset, Circle, Trim, Fillet, Extrude, Subtract, and Rotate commands to shape the complex geometry of the tools.

Wrench Head Detailing (Ring/Box End)
🔩 The ring wrench head profile involves drawing a 6-sided Polygon inscribed/circumscribed relative to a circle, followed by rotation and trimming to form the hexagonal opening for nuts.
🔢 The number "17" (likely representing a size designation) is created as text, exploded into outlines, and extruded by $-0.5$ mm (extruded downwards).
🛠️ The final detailing on the ring wrench head includes applying Fillet edges with a radius of $0.4$ to smooth the edges, which is done after Boolean operations.

3D Manipulation and Finishing
⬆️ After extrusion, the numbered text object is moved up by 6 units to sit on the surface of the wrench head, and the main wrench body is extruded by 65 units.
🔻 Two cones are created and used in a SUBTRACT operation against the ring wrench head: one cone with height $-5$ (pointing down) and another with height $5.5$ (pointing up), both with a radius of 11.
🔄 The ring wrench head (after subtraction) is rotated by 10° using the ROTATE command, and then moved up 1 unit to ensure proper alignment with the handle assembly.

Key Points & Insights
➡️ The creator maintains a supplementary blog at tukanggambar.tradeid.com where text-based tutorials are available, including email subscriptions.
➡️ Key geometric constraints were achieved using the @ notation for relative coordinates (e.g., `@20<17` for length and angle) and Shift + Right-Click for temporary object snaps (TOSNAP) like FROM.
➡️ Boolean operations like SUBTRACT are crucial for hollowing out complex features, such as creating the internal socket shape of the box end wrench.
