Hi,

Dear All, i have attached a zip file it seems to be diffilcult for me to model this, seeking for some help regarding this(addition of tutorial would be an asset).

i think no one can make this, using creo.

I don't do .rar files, so if you could include an image that would help.

Nice Darek. Welcome to the forum.

I learned a new trick about splines in sketches... select dimension and click the end of the spline, then place the dimension. Enter 0.5. This is Radius of Curvature.

Trick 2: select dimension; click the spline, click the end of the spline, click a line reference, and place the dimension. Enter an angle.

These tips have some dependencies but as a freshly created spline, you can do both of these.

Jasir, Darek's file was created using a variable named trajpar available in sweep sections. These are Variable Sweep Sections, or VSS. Very powerful capabilities for this type of challenge.

However, since each cell has a true planer-square, you have more options. In fact, there is a hidden command, Section Dome that might be useful. These challenges can take on a life of their own when you involve the industrial design people who want very specific curvatures. You need to take this into account when deciding how best to create a model such as this and how much flexibility you require.

It is possible to create the pattern by sweeping a curve along a curve. The enclosed example is built using two planar curves and a sweep. The second curve is swept along the first with a constant normal direction. This geometry is using two sinusoidal functions. The curves were created by equation where both sinusoids are expressed in parametric equations. You can change the shape by manipulation of the equation parameters. This is a single quilt that can be trimmed and matched to an arbitrary perimiter shape. Creo 2 model enclosed for reference.
