In this tutorial, we are going to make chain link using Array modifier and adjust it using the curve modifier, the chain links will be connected to each other. We will see how another object can cause the Array to change. Blender 2.90 is used.
Open Blender, delete the default cube by pressing
Add a torus by clicking
Add > Mesh > Torus on the top left
We can see that torus is not in the form of a chain link, we can change that by modifying it.
It will be easy to edit it from a side view.
On the top right, Click
Y-Axis on the Coordinate. We will switch from perspective to
Edit mode by changing from top left menu. OR, press
In the edit mode, all of the vertices are selected, click anywhere on the blank space to deselect everything, we only want to select half of the vertices. Wireframe mode will make this easier for us.
Wireframe mode by clicking the wireframe icon from Viewport Shading.
When the wireframe mode is on we can see or select the vertices that are behind the mesh. This makes our selection easier.
Select half of the vertices.
Now select the
Move tool from the left toolbar.
X-axis arrow( Red arrow) to extend the vertices.
Now our object has shape of a chain link. Go to
Object mode by pressing
Tab key. Change the Viewport Shading to
As we can see that the origin of the object is not in the center.
Press Right Mouse Button, the
Object Context Menu will appear. Click
Set Origin > Geometry to Origin.
Using Array Modifier
From the properties panel on the right side, click on the Modifiers. Properties and click
Count to increase the number of chain links.
Array modifier has an option which allows us to change the Rotation, Size and Location of the objects based on properties of another object. Right now, the chain links are not connected to each other. We will connect them with the help of an Empty object. Empty objects do not have any geometry, they cannot be rendered but they are very useful.
Add > Empty > Sphere.
Select the chain link and in the Array properties, enable the
Object Offset and under it click the
This will link the Empty sphere and the chain link.
Select the Empty sphere, and click
Since the Empty is linked with the chain link. Changing its orientation will change the orientation of the links.
Click and drag the red circle( X- axis) and type
This will rotate the object 90 degrees around X-axis.
Keeping the empty selected, select
Move tool, and then move the empty object along the X-axis to the point where the chain links look connected. This can be done better from a side view.
