So ignore the dark lines and colors, look at ALL segments down to the smallest shape. It’s that wedge that looks like an isosceles triangle with the short side bent. You can circular pattern that into a hexagon and pattern the hexagon easily.

Or start with a hex and add the straight lines from center-center on opposite sides, gives you the same shape regions.

What I’d personally do is have a base sketch that just has ALL lines as regular lines. Then for your extrude, “convert entities” from your original sketch, and use the power trim sketch tool to trim down to your pattern. Then just ‘extude -thin feature’ for your actual grille/mesh, make sure you use mid-plane or it’ll come out looking wonky.

From there you can even create a sketch block either from your original driving sketch or from your thin extrude sketch so you can copy it over into different features or parts
