C03- Modeling- Book Rack
In few of the posts of Volume 2, we got our first look at blender. We learned how to use blender, we learned to create simple objects like Cube and also learned to scale and move the objects. So now lets start making our first model.
Before we start modelling let us make some preparations, create a folder named ‘Tingu’ in your computer. Inside ‘Tingu’ folder we will create 4 more folders; name them as follows: 01-Pre-Production, 02-Models, 03-Scenes, 04-Rendering. In the ’01-Pre-Production’ folder we can keep things like our script and story board. For creating and saving our models, we will use the ’02-Models’ folder.
We will start with a simple model, lets say the ‘Book Rack’.
You already know that this is how our set will look like. We will now look into how we are going to create the rack model. I am providing the dimensions of the rack here for your reference.
This image shows us the overview of the rack. Also shown are the planks, their orientation and their dimensions. Its width is 90cm and height is 98cm. The vertical planks of each compartment are 30 cm in height and 2 cm in thickness. You need not stick to the dimensions initially, try to achieve the same shape as the one shown in the figure. I’ll show you the dimensionally correct model.
We had seen in the previous post that each model is made up of different parts.This rack is also no exception. The rack is made from joining different planks. We can consider each plank to a single cube from Blender. Thus by changing the dimension of the cube, we can have different planks. This is a very simple technique to learn, so should we start?
We will start with the base plank of the rack. We can always use the basic cube which is already present in the viewport when we open blender. But as a revision we will start from scratch and adding a new cube. We had seen this before, cube can be created from the footer of the 3D viewport. 3D View> add> cube. This will create a new cube. We can perform the same action using another method. If you see on the right hand side panel of the viewport, you will see sections like ‘Tools’, ‘Create’ etc.. The ‘Create’ section directly provides buttons to create the basic objects. Her click on the button named ‘Cube’ to create a cube.
Now that the cube is created, we will set its dimensions. This cube is the base of the rack, isn’t it? So, lets set its length to 90 cm, breadth to 30 cm and height or thickness to 2 cm. To set these values of the cube, use the panel on the right hand side of the viewport.To open this panel, press the key ‘N’ on the keyboard. The ‘N’-Panel’ will pop up.
The N-panel has a section named ‘Transform’ wher you will find ‘Location, Rotation, Scale and Dimesion’ Settings. If you check here, Dimension parameters for x, y, z will be set to 2.000. This means that the Cube is set to 2 unit size. Right now, its just a value in units, how to set it in centimeter, feet or inches we can see it in a future post. Blender’s own Units are set in ‘Meters’ even if we dont see it. So now we can enter the cube dimensions in these fields. This will make 90 cm equals 0.9 m or 2 cm equals 0.02 m. Lets add these values into the dimensions parameters. To do this, type 0.9, 0.3 and 0.02 in x, y and z respectively. This will change our cube into a long plank. Check it out! you can rotate the viewport or zoom in and out to view it clearly. Remember to press, hold and drag the middle mouse button to rotate around the object. Use the mouse scroll wheel to zoom in and out. See what happens!!
We got our base plank, wasnt it easy to make! Lets move to the next planks. We will make a copy of the first plank and use it for the second one. Goto the Tools Section inside the panel on the left. Goto ‘Edit’, here you will find a button named ‘Duplicate’. After pressing this button, a copy of our base plank is created. You will have to move the mouse a little to see the new cube created. Now we will create the vertical plank on the left side. Its height is 98 cm i.e 0.98 m. The second plank is now selected which can be easily identified by the orange border around it. We will fill its dimensions in the ‘N-Panel’. Enter the values 0.02, 0.3 and 0.98 in x, y and z respectively. This creates a vertical plank. Lets place it in its position. To move the object press ‘G’ on the keyboard. Then press ‘Z’ key to move the object upwards.Blender is a very accurate software to work in but for now we will not be more precise.
The next plank, which is the second horizontal one from the bottom, is same as that of the base plank. So we will duplicate the base plank for this. To select the base plank, right click on it. Then goto the ‘Tool Panel’ and click on ‘Duplicate’ button the same like we had done earlier. Also move it up a little using your best judgement.
We will now create the remaining of the horizontal planks. Duplicate the plank again and move up. This plank is 60 cm long i.e. 0.6 m in length. For this, type the value 0.6 in x parameter of Dimensions. This will create the plank in the middle. Now duplicate this plank and move it up. Then in the x Dimensions type 0.3. This is our top most plank.
Lets move on to creating the smaller vertical planks. We will make use of the first vertical plank for this. Right click on the vertical plank to select it. We will duplicate it. On pressing the Duplicate, if you press the ‘X’ button next, the copy will move sideways in X axis. Set its X dimension at 0.3 instead of 0.9. Now I will not be telling you the names of the buttons. Lets see if you can do it!
The next two vertical planks are very easy, we just have to duplicate the previous one and move it up and then to the side, thats it!
Our first model is ready! Check the model from all side like before. In case you find that any of the planks are out of place then you can set it back to correct position. How will you do it? First, select the plank (right click, remember!) then press ‘G’ key to move. Move the mouse, then to move the object vertically, press ‘Z’ key. If you want to move horizontally, press ‘X’ key after pressing ‘G’. After you are done moving the object, press ‘Enter’ or left click.
Now our model is ready. But now one important action is not done yet. We need to save our file, don’t we? To save our object click on the ‘Save’ button in the file menu at the top left corner. A big screen will pop up. Here select the ’02-Models’ folder from the ‘Tingu’ folder. Name the file as ‘Rack-01’ and press ‘Enter’. The files save in blender get the extension as ‘.blend’. If you check your folder our file will be saved as ‘Rack-01.blend’ in it.
If you don’t understand any of the steps given, do not hesitate to ask in the Reply section blow. You can also use Advaita Studios Facebook page to post your questions. I will definitely answer them and will be happy to explain again. Check out posts from Volume 2 5, 6 and 7 Once you know some specific tools in Blender it will easy to learn more of Blender. I will also be there to explain more need it be.Let meet in the next part, till then try making the model yourself and share your experience with me.
