Bring to front / send to back not working

In rhino 6 when I try to bring an hatch in front of a series of line to hide them (it would be very difficult for me to do otherwise) although I see it correctly in the view port when I go printing the lines comes back in front of the hatch.

Anyone knows why this is happening and if there is any workaround?

Thanks in advance

Hello - I think this may have been fixed -


This was recently fixed in the upcoming SR12 which we should be releasing an initial release candidate for next week.

Here’s the bug that I fixed that sounds similar to what you are seeing

If you need this functionality today, you can use one of our internal builds of SR12 that we produce every day. Just let me know and I can send you a link
