Patching lights

This depends a bit. If you're in a venue that has a permanent lighting rig that (mostly) doesn't change from production to production you can re-use a previous showfile where you delete everything that was show-specific, like cues.

Most of us, in that situation, use a starter showfile that has everything that stays the same all the time, so we don't have to take the last show's showfile and delete specific stuff from it.

Ok. I think I understand if I create a new showfile then they would have to be patched.

Correct. File>New will create an empty showfile, i.e. without patch

Makes sense now. Thank you
