Greetings to all. In this class, we will go through the procedure to apply the materials on the model components, and the procedure to finish the entire building by duplicating the entire floor. Let's get started. Now, we apply materials on the components. We first open layers and make floorslabs invisible so we can see the inner walls. And now, we paint the wall group. We choose a material to add on it. We can see all the inner walls have been painted. Next, we check if there is any wall face left behind. Moreover, if we are favored with various wall materials, we could click into the group and paint the wall one by one. Now, we apply materials on columns. We choose a brick material to add. We could zoom in to check whether the dimension is close to reality. We choose tape measure tool to check. We can see the results is about 20 centimeters. It is reasonable. Next, we check if there's any face left behind. Now, we apply materials on some beams. Steps are same with walls and columns. We choose a material to add and check if there's any face left behind. Next, we paint the components. We first paint the air-conditioner platform. Click into the components and color it. After finishing it, we can see other components has been changed too. Next, we paint window components. Follow the steps mentioned before. There we get the windows done. Now, we know how to add materials to components. So, the door component won't be the challenge. We also need to check if there's any face left behind. After we finish our floor, we open a floorslab layer and group them up to make the components. Same goes to second floor, the top floor and the foundation. Our building has five floors with a top floor. So, we can make copies of the second floor to create the above floors. Notice the reference points to create the copies. Our building has five floors so we create three copies. After duplicating the floors, we add our top floor and a foundation to it. And like this, we have our building basically done. In this class, we modified and duplicated the entire floor, and by this we have finished the building. There are other details that we need to correct and modify. Let's stop for now. Goodbye.
