I have an equation driven sketch that I have wrapped (emboss) over tube. This wrap feature is then circularly patterned around the axis three times to form a ring. This ring is then linearly patterned along the axis thirteen times. At either end of the stent, the linkages that connected the rings together need to be trimmed off. However, I am running into a hang up in getting rid of them. I have tried copying the first sketch and wrapping (deboss) this onto the outer face of the part before circularly patterning the deboss feature. The deboss feature works fine to eliminate one of the tabs, but the circular pattern does not remove the remaining two tabs. When I click an axis to pattern around and then the green check on the circular pattern tool, Solidworks does not give me an error, just refuses to execute the command.

I thought about trying to create a surface that intersects where I want to trim the part and then using the split feature. My issue is that the area to create a surface is curved in multiple directions (around the axis and following the sketch pattern). I am not sure how do this. Additionally, I am afraid doing this route may be even more difficult to handle with an equation driven model. Does anyone have a suggestion how to resolve this? I am also open to other solutions on how to tackle removing the linkages at either end of the part. Thanks in advance for your help.

Black rings in picture are the linkages to remove and the green is where it has been removed by the deboss feature.
