So I tried making a door using hinges but uh it did not work.
So, if there’s any help you can give, please say so in the comments, thanks!

It looks like you are trying to attach Attachment 1, the edge, to Attachment 2, the center.
Try placing Attachment 2 at the same place of Attachment 1, but on the top of the door.
As @eatabler0ck stated, your HingeConstraint Attachments need to be at the same place.
I usually put them halfway up the door so they are centered. I also copy the WorldPosition of the Attachment I put in the right place, then paste it into the other Attachment’s WorldPosition. You don’t have to worry about Position alignment issues that way.
The model I linked is one I made to show other people how to have a scripted opening door with the HingeConstraint set to Servo.
