Cara Gambar dan Render Hexagonal Mur dan Baut di AutoCAD

Summary

In this tutorial, the presenter demonstrates how to draw and render a 3D hexagonal bolt in AutoCAD. Starting from creating the bolt head with a hexagonal polygon, the video covers extruding, applying chamfers, and adding a thread profile using a helix. The process also includes creating the bolt's body and hexagonal nut with similar steps. The tutorial provides detailed instructions for visualizing and rendering the final product, ensuring users can replicate the 3D design and achieve realistic renderings with AutoCAD’s material and environment settings.

Takeaways

• 😀 Introduction to creating and rendering a 3D hexagonal bolt in AutoCAD, with the final result shown after rendering.
• 😀 Encourage viewers to like, subscribe, and share the video for support and to reach a wider audience.
• 😀 The AutoCAD settings used include 3D modeling workspace, auto-snap, and top view for the drawing.
• 😀 The process starts by creating the head of the bolt using a polygon with 6 sides, setting the correct radius, and extruding it to a height of 7.5.
• 😀 After setting the head, the next step involves adding a circle on top, extruding it downward at a 45° angle for the beveling effect.
• 😀 A cylinder is created for the bolt shaft with a 5 mm radius and a length of 35 mm, then chamfered at the bottom.
• 😀 To create threads, a helix is drawn using a 5 mm radius and a pitch of 1.2 mm, then extruded to form the threading along the shaft.
• 😀 The helix is aligned and adjusted for proper placement using the 'best point' option for smoother creation.
• 😀 The bolt profile is sweated along the helix to create the thread, which is completed by adjusting and finalizing the extrusion.
• 😀 The process for drawing the nut involves a similar approach, starting with a hexagonal polygon, creating an inner circle for the hole, and extruding it.
• 😀 The tutorial concludes with the final rendering of the bolt and nut, where materials are assigned (e.g., aluminum) and environment settings are adjusted for a clean render result.

Q & A

What is the main objective of this tutorial?

The main objective of the tutorial is to teach how to draw and render a 3D hexagonal bolt using AutoCAD.

Which AutoCAD settings are used in this tutorial?

The tutorial uses the 'Workspaces 3D Modeling' view, with Auto Snap, Snap, and Ortho Snap settings enabled for easier drawing precision.

How do you create the hexagonal head of the bolt in AutoCAD?

To create the hexagonal head of the bolt, the 'Polygon' command is used with 6 sides. The inscribed circle option is selected, and the radius is set to half the dimension of the bolt head (17mm, so the radius is 8.5mm).

What is the method to extrude the polygon into a 3D shape?

The 'Extrude' command is used to pull the polygon vertically. A height of 7.5mm is set to create the 3D head of the bolt.

How is the conical shape for the bolt's head created?

A circle is drawn on the top surface of the polygon, extruded at an angle of -45°, and then the 'Intersect' command is used to form the chamfered edges.

What is the process for creating the bolt's cylindrical shaft?

The 'Circle' command is used to create a circle with a 5mm radius (for an M10 bolt), and then the 'Extrude' command is used to extend it to a length of -35mm (downward).

How is the thread of the bolt represented in AutoCAD?

The 'Helix' command is used to create a helix with a pitch of 1.2mm, and then a profile of the thread is drawn using the 'Line' command, followed by the 'Sweep' command to apply it to the helix.

What is the method for creating the nut to match the bolt?

The nut is created by drawing a hexagonal polygon with a radius of 8.5mm, similar to the bolt's head. A hole is created in the center using the 'Circle' command, and then it is extruded and subtracted to form the inner hole of the nut.

How are the nut and bolt aligned in AutoCAD?

The 'Copy' command is used to duplicate the nut, and the 'Move' command with Ortho mode ensures the nut is aligned vertically to the bolt. The nut is then rotated by 90° to fit onto the bolt.

How is the final rendering of the 3D bolt and nut achieved?

The final rendering involves selecting the appropriate material (e.g., Aluminum), setting the background to solid white, adjusting the rendering size (3300x250px), and then executing the render command to visualize the 3D model.
