AutoCAD 3D Nut How to Draw Nut, Nut 3D Training Beginner, 3D Modeling

Introduction

This tutorial will guide you through the process of creating a 3D nut in AutoCAD. It's designed for beginners who want to learn basic 3D modeling commands and techniques. By the end of this tutorial, you'll have a solid understanding of how to use essential AutoCAD commands to create a 3D nut.

Step 1: Start with a Circle

1. Open AutoCAD and create a new drawing.
2. Use the C command to draw a circle:
   • Type C and hit Enter.
   • Specify the center point by clicking on the desired location in the drawing area.
   • Enter the radius of the circle (e.g., 10 units) and hit Enter.

Step 2: Create the Nut Profile

1. Use the POL command to draw a polygon:
   • Type POL and press Enter.
   • Specify the center point of the polygon at the same center of the circle.
   • Enter the number of sides (6 for a hexagonal nut) and the radius (ensure it fits within the circle).
2. After creating the polygon, use the EXT command to extrude the shape:
   • Select the polygon.
   • Type EXT and hit Enter.
   • Specify the height of the extrusion (e.g., 5 units) and hit Enter.

Step 3: Create the Inner Hole

1. Draw another circle inside the polygon:
   • Repeat the C command to create a smaller circle at the same center point.
   • Enter a smaller radius (e.g., 5 units).
2. Use the SUBTRACT command to create the hole:
   • Type SUB and press Enter.
   • Select the extruded polygon first, and then select the smaller circle.
   • Hit Enter to create the hole in the nut.

Step 4: Adding Threads (Optional)

1. Use the HELIX command to create a thread-like feature:
   • Type HELIX and press Enter.
   • Specify the base point (start from the edge of the nut).
   • Set the height of the helix and the number of revolutions to simulate threads.
2. Adjust the helix parameters as needed to fit your design.

Step 5: Rotate the Nut

1. Use the ROTATE3D command to position your nut:
   • Type ROTATE3D and press Enter.
   • Select the nut.
   • Specify the axis of rotation and the angle of rotation as required.

Conclusion

In this tutorial, you learned how to draw a 3D nut in AutoCAD using basic commands like circle, polygon, extrude, subtract, helix, and rotate3D. With practice, you can create more complex models and designs. Explore additional features in AutoCAD to enhance your 3D modeling skills further. Happy drafting!
