3D Shapes: Screw & Nut Generator
 |  Miłosz Skubis

Welcome to the article dedicated to SelfCAD's 3d modeling tool called 3D Shapes, in which I'm going to explain the process of creating and customizing shapes with the help of the Screw & Nut Generator. As you can see, Screw & Nut has been placed in the section below the divider, which marks it as one of the more complex shapes available in SelfCAD. Because of this complexity, the customization process is much more complicated than it was in the case of basic shapes.

Adding shapes

There are two ways you can follow to add shapes to the grid. The first of them is by simply selecting the Screw & Nut from the drop-down list and then dragging it to any place in the grid. It’s the quickest way to add shapes, but the downside of this method is that it skips the customization process and adds its basic version.

 

 

 

 

 

 

 

 

 

The second option is by selecting the Screw & Nut from the drop-down list and simply clicking on it. This way, you’ll open the Tool Setting Panel on the left side of the screen, with all of the customizable features available for it. To finish the customization and add the model to the grid, you have to confirm the changes by pressing the tick button at the top of the panel.

 

 

 

 

 

 

 

 

 

Customize: Hide all objects

Hide all objects is a feature enabled by default, and as its name suggests, it hides every other object previously added to the grid. It allows you to customize the current model without other models overshadowing it.

 

 

 

 

 

 

 

 

 

Customize: Generate Screw & Nut

Generate Screw and Generate Nut - there is no need to explain what each of them does. What's worth noting about them, however, is the fact that you can easily model both of them at the same time, as both models will complement and fit each other.

 

 

 

 

 

 

 

 

 

Customize: Radius

Radius is one of the features responsible for setting the size of the Screw & Nut. The only thing worth noting about it is that it always measures the radius of the screw, so during the creation of the nut, it will measure the size of the screw that goes into it.

 

 

 

 

 

 

 

Customize: Pitch

Pitch is the second feature responsible for the size of the model. It's very straightforward, as it only sets the height of both the screw and the nut. You should remember, though, that increasing the length of the screw will dilute its thread.

 

 

 

 

 

 

 

 

Customize: Segments

Segments set the overall level of the details of both the Screw & Nut. Increasing this value will result in a much smoother object while lowering it, will make it cruder and deformed. Be aware that simplifying too much will make the Screw & Nut unusable.

 

 

 

 

 

 

 

 

Customize: Rotations

Rotations refer to the density of the thread of both the Screw and the Nut. You might want to increase it when you increased the length of the Screw & Nut, and its threads became too spread out.

 

 

 

 

 

 

 

 

 

Customize: Top Offset

Top Offset is a setting available only for the Screw Generator, and it allows you to customize its tip. The Screw is flat by default, but with this feature, you'll be able to add and model a little spike at the top.

 

 

 

 

 

 

 

 

Customize: Tip Scale

Tip Scale is a feature that allows you to change the thickness of the thread near its ends. It's available for both the Screw and the Nut. Be careful not to make it too thin, as it may break the thread during printing.

 

 

 

 

 

 

 

 

 

Customize: Tip Segments

Tip Segments is a complementary setting to the Tip Scale, which allowed you to create a thinner thread at the ends. Tip Segments, on the other hand, allow you to set the length of the thread that will be trimmed.

 

 

 

 

 

 

 

 

 

Customize: Thread Scale

Thread Scale refers to the thickness of the thread. Previous settings allowed you to customize the ends of the thread, and here, you can change its overall thickness, depending on the used value.

 

 

 

 

 

 

 

 

 

Customize: Outside Edges

Outside Edges is a setting available only for the Nut generator, and it allows you to set the number of edges on the outside of the Nut. Do be careful of making it too rounded, as it might make it hard to twist it tightly.

 

 

 

 

 

 

 

 

Customize: Position

You can use the Position feature to change the placement of the object within the grid. You're able to manipulate it by changing the values in the text-boxes, where each of them represents the position on one of the three axes. You can use both positive and negative values, which will change the direction of the movement on the axis.

 

 

 

 

 

 

 

 

 

Customize: Rotation

The Rotation feature allows you to set the angle of rotation of the object within the grid. You're able to manipulate it by changing the values in the text-boxes, where each of them represents the rotation on one of the three axes. You can use both positive and negative values, which will change the direction of the rotation around the axis.

 

 

 

 

 

 

 

 

 

And that's all there is to the Screw & Nut Generator. After reading this article, you should have a general idea about its creation and the customization process behind it. Of course, the graphics shown here were just examples, and any change in the settings will impact the overall shape of the object, but their underlying principles will always stay the same. And that's all I had for you. I wish you success in your future projects. See you, and stay tuned for more content to come!
