Curic face knife

I’m having an issue using curic face knife where it’s deleting the entirety of the object, rather than the chosen shape. Has anyone had this before? And would know how to rectify?

Do you know what this object looks like? What are its dimensions? Where are you trying to cut it? What shape?

Hey Mihai. It was an L shaped deck. I ended up just inputting every board manually.

I have it all grouped, not in components, would that be a factor? I just got it to work on a different project. The only difference was that I have the others as a component

It can also cut nested groups and components without any problems.
