Greetings to all. We have finished drawing all the structural elements for this building, but we need to make some adjustments. Into this class, we explore and fix all the problems in our building, so, all elements will intersect between them. Let's get started. Now, to adjust the walls height, we need to look at the wall group. Here, we will find lots of problems with the height, because if the wall intersects the beam, then the wall is high, we won't see the beams but the height. If the floor page shows that the walls and beams are intercepted, then the walls should be lower than beams in a 3D model. So, we have to lower the wall. You can see lots of the same cases in the structure. We use a line tool to draw the line and make the wall become two pieces. Here we cut the wall, because the height of the right part wall is correct, but the left part wall, should be lower than the beam. So, we push the wall down for 60 centimeters, since the beam height is 60 centimeters. Copy the view to adjust the wall one by one. This operation requires some experiences. It may seem nothing special, but you have to do it yourself. Without practicing, you may not do it differently. You have to be quite familiar with the operation so that you know how to cut, how to push, how to find the interference points. Eventually, you don't need to think, you can almost do it automatically. Last, check if the problems are fixed. After checking, we've finished the adjustment of the walls. Today, we finish the last class for the building structural module. We learned the best practice for drawing these kind of elements with the supporting tools provided by Sketch app. We also learn how to measure all of them using layers. And we also created a systematic procedure of drawings. Let's stop learning for now. See you in the next module.
