Tips & Tricks





Welcome to the article, in which we are going to learn about SelfCAD's 3D modeling tool called Inflate. I am going to explain all of its ins and outs and present its general applications. On top of that, I will share a few Tips and Tricks that you could use with Deformations.

Inflate is one of the basic Deformation tools available in SelfCAD, and you will find it in the main Toolbar, in the Deform drop-down list. As its name suggests, it allows you to deform selected figures or their regions by flattening them from the sides.

Deform is a unique category because tools in it rely heavily on the level of the detail of the objects. It means that by increasing their Resolution, you will achieve a much smoother and detailed deformation. On top of that, with the Advanced Settings such as the Symmetry, Origin, and the Local and Individual Transformation, you can customize the Inflate even further.

Follow this article to learn all about this tool!


Select the object

Selecting the object on which we will use the Inflate tool

The first step of using any modeling tool is selecting the object on which you want to use it. You can select objects by either left-clicking on them in the workspace or by selecting them in the Object Management section, in the right-side panel. The second option has an in-built search engine, which is extremely useful when you are working with multiple objects.


Activate the tool

Activate the Inflate tool by selecting it from the Deform drop-down list or using a shortcut

Once the object is selected, you can activate the Inflate tool by selecting it from the Deform drop-down list or use a shortcut by pressing the ‘D+I’ combination on your keyboard. This way, you’ll open a Tool Setting Panel with all of the customizable options for this tool on the left side of your screen. Activating the Inflate tool will also enable the Gizmo that you can use to Deform the object.



Inflate the selected model by dragging the gizmo

The first option to inflate the selected object in SelfCAD is by dragging the Gizmo mentioned in the previous paragraph. As you can see, it points in different directions, which indicate in which dimension and in which way you can inflate the object.

Inflate the selected object by typing values into text-boxes

The second way to inflate the object is by typing the exact values into the text boxes in the Tool Setting Panel. Furthermore, you can use the checkboxes to copy the same values between the text boxes. Each of them refers to one of the axes, whose position you can check on the 3D Coordinates Axis on the bottom right side of the grid.



Select a region

Select the region that we can use Inflate on

SelfCAD allows you to not only inflate the object itself, but you can also inflate some of its regions. To do so, you need to select them first. In the Right Side Panel, you will find an Interactive Rectangle, where you can enter one of the following selection modes: Face, Vertex, and Edge. Then, you can select the parts of the object that you want to inflate.


Inflate a region

Inflate the selected region by dragging the gizmo or text-boxes

Inflating a region works exactly the same as inflating the object itself does. After selecting a region or regions that you want to deform, you can either drag them with the help of the Gizmo or type in the values into the text boxes to inflate the selected region with the typed value.



Inflate a profile

In SelfCAD, there is an option to Inflate the Profiles as well, drawn with the help of the Freehand or 3D Sketch tools. The process is exactly the same as described above. After selecting the profile from the Object Management Panel, all you have to do is Inflate it with either the Gizmo or by typing values directly into text-boxes. Of course, most profiles consist of multiple regions, which means that you can Inflate them individually as well, as explained above.




Toggle to enable the symmetry setting for Inflate tool

Symmetry is the first option that you will find in the Advanced Settings of the Inflate tool after expanding the drop-down list. After enabling this feature, as its name suggests, you will inflate the selected object proportionally to the used axis.



Customize the point of origin for the Inflate tool

Within the Advanced Settings of the Inflate tool, there is an option called Origin. Origin sets the position of the Gizmo. In practice, you can use it to set a point from which the object will inflate. You can choose the point of Origin from the options available in the drop-down list.


Manual gizmo position

Customize the Manual gizmo position of the Inflate tool

Manual gizmo position is an extension to the Origin feature with only a single difference. While Origin allows you to set the vertical position of the Gizmo, here, you can manually set its horizontal position to any place in the workspace.


Local transformation

Toggle to enable the Local Transformation setting for the Inflate

Local Transformation is another feature available in the Advanced Settings of the Inflate tool, and it is available only when you are inflating the regions of the object. By enabling this option, you will move and rotate the position of the Gizmo, so it's positioned flatly on the selected region, which will allow you to deform it independently from the rest of the model. To use this option, you have to enter a specific Selection Mode and then select the region of the object that you want to inflate. You can go back to Select and Move a region paragraphs for a more detailed explanation.


Individual transformation

Toggle to enable Individual Transformation setting for the Inflate

Individual Transformation is another feature available in the Advanced Settings of the Inflate tool, and it is available only when you are inflating at least two separate regions of the object. As the name suggests, by enabling this option, you will inflate selected parts independently from each other. Again, if you need a reminder on how to select a region, you can go back to previous paragraphs for a detailed explanation.


Minimum Step Size

Customize the Minimum step size for the Inflate tool

Minimum Step Size is one of the most useful features when it comes to precise modeling, and you have to operate on strict values. It locks the tool at a specified value, and it will inflate the object by the multiplication of this value. For example, if you set this feature to 60, then you will be able to inflate the object by 60 units on any axis, which will be the first step. When you try to inflate it further, it will do so by another 60 and so on.




You can use up to four Viewports to see the changes made to the model from different perspectives.



And that’s about it for the Inflate. After reading this article, you should know the basics of the Inflate tool and how to use it, know about its different applications and how to implement and customize its advanced settings. Of course, the graphics shown here were just examples, and using this tool on other shapes will give you slightly different effects, but its underlying principles will always stay the same.  


That's all I have for you today. I wish you success in your future projects. See you, and stay tuned for more content to come!
