Bloxburg build mode doors

Hello! How do the developers of Bloxburg make their door system for build mode? What techniques do they use? I’ve looked around the dev forum and couldn’t find the answer I am looking for.

They might be using unions using an invisible part consisting of the entire door model’s physical regions as a negative part, or figuring out how big to set the negative part at runtime using the model’s boundary box (I forgot the actual term). Whereas the wall is the union, the invisible part from the door is part of that union. Try that.

Source: I’m in no way qualified. For all you know I could’ve made whatever I said up. But try.

I was once commissioned to make a similar system, which included doors.
You should look into GeometryService.
Keep in mind that it’s pretty advanced and requires a ton of math to work properly
