Need help creating a circular cutout mesh around a cylindrical shape

Hello. I made a wrap pattern on a patio heater design, which I would like to circle pattern all around the cylinder by roughly 140 times. And although it shows on the preview, solidworks crashes when I attempt to confirm. Just even trying repeat the pattern 3 times takes almost a minute. Is there something wrong I am doing, or a better way of achieving the result that I want? Please see the attached files, and any help is appreciated, thank you.
