3D Shapes: Spiral Generator
 |  Igor Idzik

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 Spiral Generator. As you can see, Spiral 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 Spiral 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 Spiral 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: Top radius

Top radius is one of the features responsible for changing the overall size of the Spiral, and it allows you to set the size of its upper end. You can change its value by manipulating the slider, or by simply typing in the value into the text-box.

 

 

 

 

 

 

 

 

 

Customize: Bottom radius

Bottom radius is the second feature responsible for changing the overall size of the Spiral, and it allows you to set the size of its lower end. If there is a difference in size between the top and the bottom, the software will render a nice transition between them, slightly deforming it in the process.

 

 

 

 

 

 

 

 

 

Customize: Height

Height is the last feature responsible for changing the overall size of the Spiral, and it allows you to set its size on the Y-axis. A thing to look out to is that changing the height will impact its density.

 

 

 

 

 

 

 

 

 

Customize: Revolves

Revolves allows you to set the extent of rotation of the spiral. It will increase not only its overall length but its density as well. Just like before, you can change its value by moving the slider, or by directly typing the values into the text-box.

 

 

 

 

 

 

 

 

 

Customize: Top Thickness

Top Thickness is one of the features responsible for changing the width of the profile of the Spiral, and it allows you to set its size at its upper end. You can change its value by manipulating the slider, or by simply typing in the value into the text-box.

 

 

 

 

 

 

 

 

 

Customize: Bottom Thickness

Bottom Thickness is the second feature responsible for changing the width of the profile of the Spiral, and it allows you to set its size at its lower end. If there is a difference in thickness between the top and the bottom, the software will render a nice and smooth transition between them, so you don't have to worry about any sharp edges.

 

 

 

 

 

 

 

Customize: Edges

Edges is one of the two settings responsible for the overall shape of the Spiral, and with this feature, you'll be able to manipulate the shape of its profile. By increasing the number of edges, the profile will become more and more rounded.

 

 

 

 

 

 

 

 

 

Customize: Radial Segments

Radial Segments is the second setting responsible for the overall shape of the Spiral, which in this case, translates roughly to the roundness of the object. By increasing their number, you will make the spiral look more rounded, as well as add more details to it.

 

 

 

 

 

 

 

 

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

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 Spiral 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!
