You can start with a simple plane.
First set modifiers to it:
Mirror on X and Y
Array on X (merge option checked)
Array on Y (merge option checked)
In edit mode grab the plane to set the origin point to bottom left.
Poke face CtrlF then choose 'poke'.
Select the outer edges.
Subdivide them W then choose 'subdivide'.
Select the bottom left and upper ...
Using the "Create Pattern" function that comes along with the TexTools add-on you can create the base for the pattern the following way:
Go in top orthographic view and make sure you are in Object Mode
Press Shift+A and select "Create Pattern"
Select the Diamond pattern and set the "Size" to "2", leave "Scale" at 1.0
Go in Edit Mode and cut the square once ...
You can replace the curve modifier by a simple deform modifier.
The point of interest is to augment the second array count until the holes stretching disappear.
Thanks to the deform modifier this is much more easy to tune than the curve modifier.
Add an empty at the same X,Y location than your grid.
Add a simple deform / bend with an angle of 360 and ...
You could go with the Bend, using limits and Axis/Orientation Empties in the modifiers, but IMO, you would get finer control over the curves using Curve modifiers throughout?
Excluding the flat region from the circular curve modifier
In order to keep the end of the folded-over region flat, it must remain unaffected either by the mapping of the entire ...
Click on the triangle with vertices icon - last one on top row of SubSurf modifier panel.
Not always you want to have it enable in Edit mode since it can be sometimes quite confusing moving vertices affected by modifier. SO if you will have difficulties disable it to check situation.
Thanks. I didn't think about starting it from a Circle. Total beginner.
I didn't figure out how to separate those vertices. I just select each one and pressed "V" to separate them one by one. I'm sure there's an easier way.
Anyway here's my final result. Thanks again :)
Bevel does not work very well in this case, even with only one boolean.
Though, for the second boolean a workaround is to use a mirror instead:
The empty set as mirror object is located at the sphere center and rotated 45 degrees around Z.
Use the [curve modifier].
See a video tutorial on the famous video website or search here at BSE.
You can also use [Simple Deform] modifier.
You can also use proportional edit.
You can also use an armature modifier.
I am not sure, but having multiple verticies may be the problem. Merge them Alt + M and then see what the results are.
Some other things to consider are what your edge flow is like at those positions. If there are no edge creases or loop cuts, then the subdivision modifier may round your objects at those locations. With lighting, normals etc, this may be ...
