[MUSIC] Greetings to all. In today's class we will create the walls of our building. This is very exhausting work but is necessary to give the shape to our building. Here, it's very easy to make mistakes. So we try to do it very carefully. Here again, we will use the Rectangle tool, Push/Pull tool and let's get started. Now, we draw the walls. We first add a new layer and we give the name wall. They would chose this as an active layer. The columns are all obstacle for us, but we're trying to draw the walls. So we make the column layers invisible to avoid problems while drawing. Now, we won't bother by the columns. After this, the use the Rectangle tool to trace the rectangle that forms the selection of the wall. Then we use Push/Pull tool to pull this up to 420 cm. We can convert Push/Pull cursor over the other face to make two face the same height. If the face we draw is gray, that means that's the inner part of the face. So when you right-click off the face and select Reverse Faces to switch faces and show the exterior out face. Then we can pull it, orbit to the outer side to make it easier to draw. Zoom into the place we want. The face that is fully surrounded by walls will also generate a new face. Here we click the generated face and then erase it. Put a wall up to 420cm. For the rest of the walls, we can click on it twice to pull it, too. The doors should also be drawn as part of the wall. The door has a space over it that is also part of the wall. So to make the drawing process easier we draw the wall first. Then we rest the wall space where the door will be placed. And then we insert a door in this space. Click twice to pull the wall to the previous height. Then, you raise the new generated face. Here's a tip to draw the wall. Draw the wall from inside to outside because if we draw the outside wall first, it will be harder to draw the walls inside due to obstruction created by the outside wall. So we usually draw the walls from inside to outside. Don't care about the doors and windows we will deal with those afterwards. Some places of the wall are disconnected this is the place for columns. When we make the columns visible later. We will seem them connected. We have to be patient, it's almost done. Last, check if the walls are all done. When we finish drawing the walls, we also need to grow them. To do that, we make other layers invisible, then we let all the walls. Right click and select Make group, and we finish the wall part. So we have finished one of the most tiring process of the entire course. Congratulations. Of course, there are more things to do next but for now let's stop. We will keep drawing in the next classes. Goodbye. [MUSIC]
