Greetings to all. In this class, we will learn how to use 3D warehouse to get models and place this in our model. Because the open source models may not be in the size that we need, we will use a Scale Tool to fit the model in our drawing. We may need to modify it a little bit, for this, we will use Rectangle Tool and the Move Tool. Let's get started. Now to draw the rolling door, we first click file, then select 3D warehouse, then get models. Here, we input rolling door first and then we look for a suitable rolling door model. Once we find the rolling door model, we click the download button in the bottom right to insert this model directly into the model. We will rotate the door to the right direction. We know that the rolling door should be 300 by 355 centimeters. So we choose the Scale Tool. Click the upper middle point and input 300 cm. Then click the side middle points and input 355 cm. Next, we double click the wall to enter the wall group. First, we choose X-Ray style for editing our model more easily. Find a position of rolling door, then use rectangle tool. Start from the side and input 355,300. Next, we push this to create a hole where we will fill the rolling door. After this, we do this process again on the other side of the wall. Draw the rectangle, input 355,300 and push it. Now we use Move Tool and from the bottom left of the rolling door, we move it to the hole we just created. We can zoom in to do this precisely. Then we copy the rolling door to the left side. Press control key and move it to the left side like this. We've finished placing the rolling door in our model. In this class, we learned how to download models from the sketch of 3D warehouse. Now we can use and modify other models or get inspired by those open source model, and improve our models. Remember that those models are not going to be at the same scale or fully completed to you, you may need to modify them to make them work in your model. Let's stop for now. Goodbye.
