We focus on quickly coding to verify our idea by selecting a single door, reading its properties, and writing to a parameter. I demonstrate how to handle errors and the importance of using transactions when modifying the model. By the end, you’ll see how to determine if a door is mirrored or regular, and I encourage you to test this functionality in your own projects. Stay tuned as we will expand this concept to all doors in the next session.
