How do cutting patterns which go over the model?

I want do do X cuttings across my whole surface. But im getting errors for cuttings that go over the model. Tutorials doesn't show how to do such patterns

One way to accomplish this is to approach it from the top, making a linear pattern of the angled lines that extends enough to cover the entire top surface. Use the sketch Use tool to capture the top perimeter and trim the lines that extend beyond the top and Extrude/Remove the resulting parallelograms down. - Scotty example

@dominik_panas , try turning on the "Reapply features" checkbox in the Linear pattern dialog

@dave_lapthorne Yes! that was it! Thank you. I assume that this option does not just copy the feature re-apply it accordingly to current shape right

@dominik_panas: you are correct: it will apply that extrude time and time again. and because it calculates the feature and resulting geometry one by one, it is not the fastest loading way.

If I were you, and only if it matters, i'd actually model just one of those rombus features, use a face pattern across a rectangular block that's actually too big so all the rombusses will fit on the top face. then intersect that block with a new extrude to cut it to the final shape.

I expect that to be quite a bit faster
