Cut through Polysurface

Hi everyone.

I created though an array and a flow along surface a facace that i want to cut now to make it a lot more dynamic. Thing is its not cutting with wirecut, boolean nor trim. What can i do? Example on the right is exactly what i want (made it through a boolean difference).

Hello - it is hard to say without having the file but, Boolean operations fail where there is an incomplete intersection. If you flowed the pattern onto a cylinder, then most likely the ends of the pattern do not meet cleanly - in the case of a regular pattern on a cylinder, flowing is perhaps not the ideal way to go - better to build a single repeat of the pattern and ArrayPolar, but I am just guessing at the problem - feel free to Export the objects (Save Small) and send to tech@mcneel.com, to my attention, with a link back to this topic in your comments.
