    9 The program has a standard user interface with toolbars and menus. The big white area on the left is the main drawing area and on the right there's a list of available pieces with a picture of the currently selected one and list of colors.
     9LeoCAD has a standard user interface with toolbars and menus. The big white area on the left is the main drawing area and on the right there's a list of available pieces with a picture of the currently selected one and list of colors.

    1111Note that user interface is different between Operating Systems so if you're not running the MS Windows version of LeoCAD your screen won't look exactly like the screenshots here but they will be still close.
     
    2121TIP: You can use the grid to help you see better where each piece is located. You can do that by  choosing "Preferences" under the "View" menu, then going to the "Drawing Aids" tab and checking the box "Base Grid". Also note that the X/Y/Z location of the currently selected brick is shown on the lower right corner.

     25Now select "Plate 2 x 4" from the list of pieces and add it next to the first piece. After you add a piece the mouse cursor changes to an icon that looks like four arrows, that means that if you now keep the mouse button pressed and move the cursor the objects that are currently selected will be moved. If you look at both bricks, you’ll see that the new brick has a blue outline, that means that it is selected and it will be modified when you drag the mouse.
     26
     27While holding the left mouse button down move the mouse and position the new piece 2 "units" from the first piece like the next picture.

     30
     31TIP: To move pieces one axis at a time you can click on the axis arrows (1), or use the keyboard (default keys are the arrow keys, Page Up and Page Down).

    27 === rewrite the rest ===
     35We want to make instructions in a way that people can see the order that we added pieces to the model so we need to split the building instructions in "steps".
    2836
    29 Now select "Plate 2 x 4" from the list of bricks and add it near the first brick. After you add a brick the mouse cursor changes to a four arrows icon, that means that if you now keep the mouse button pressed and move the cursor the objects that are currently selected will be moved too. If you compare both bricks, you’ll see that the new brick has a blue outline, that means that it is selected and it can be modified.
     37Since now we'll be adding pieces on top of the existing pieces it's a good time to do so in another step, so click on the the right arrow icon (1) on the top right toolbar. If you look at the status bar at the bottom of the screen, you’ll see that it now says "Step 2" on the right side (2).
    3038
    31 While holding the left mouse button down move the brick so that it stays 2 "units" from the first brick. You can also use the arrow and page up/down keys to move the bricks if you prefer.
     39Add a "Plate 2 x 8" just above the first pieces, we are going to use it to hold the first two bricks together so we will have to rotate it until it's in the correct position. Select the "Rotate" icon from the toolbar (3), the cursor will change and then drag the mouse until the brick is rotated 90 degrees.
     40
     41'''Picture goes here'''
     42
     43TIP: Just like moving, you can also rotate around one axis at a time by clicking on the circles that appear around the currently selected piece, or by using the keyboard (default keyboard shortcut is hold the SHIFT key down while pressing the arrow, Page Up or Page Down keys).
     44
     45----
     46
     47Now go to step 3 of the project and let's keep building our car. We need to add a steering wheel and mudguards next but if you're not familiar with naming convention of the Pieces Library it can take a while to find out which category a piece belongs to but luckly we can quickly search for pieces.
     48
     49Type "Car Mudguard" in the search box (1) and press Enter. LeoCAD will search all piece names for the text you typed and display the results in the category tree under "Search Results" at the bottom of the tree.
     50
     51Select "Car Mudguard 2 x 4 without Studs" and add it to the model, then do the same for the steering wheel and you’ll have something like this:
    3252
    3353'''Picture goes here'''
     
    3555----
    3656
    37 Now let’s go to the second step of our project, so advance 1 step by clicking on the icon on the toolbar (1). Take a look at the status bar at the bottom, you’ll see that it now shows "Step 2" on the right.
     57Advance the instructions another step and add a "Slope Brick 45 2 x 2" above the mudguard and another to the front of the car.
    3858
    39 Add a "Plate 2 x 8" just above the first bricks, we are going to use it to hold the first two bricks together so we will have to rotate it until it’s in the correct position. Select the "Rotate" icon from the toolbar (2), the cursor will change and then drag the mouse until the brick is rotated 90 degrees. In the beginning it will be difficult to rotate using the mouse so you can use the keyboard instead, hold the SHIFT key down and press the Page Up key 3 times.
     59Let’s also add another "Plate 1 x 4" to the car, LeoCAD remembers that you recently added one so you can quickly go back to it by clicking on the arrow to the right of the search box (1) and selecting it from the list of recently added pieces.
     60
     61Here’s the picture of the almost complete car:

    45 Go now to step 3 of the project, and let’s add some other elements to our car. We’ll need a steering wheel and a mudguard now but as you don’t know where to find those, just type "Car Mudguard" in the search box (1) and the program will show you where it is. Select the "Car Mudguard 2 x 4 without Studs" and add it to the drawing. If you scroll the list a little you’ll find the steering wheel just below so add it too and you’ll have something like this:
     67There's one very important thing missing in our car: the wheels, but before we add them we need to add the wheel holders so let's do that on step 5. It's not going to be easy to see the bottom of the car from the current camera position so we should rotate the camera around the car but we don't want to change the camera position for the previous steps.
     68
     69To make changes not apply to previous steps LeoCAD uses a concept called keyframing, that means that any changes made to a key frame won't affect previous steps, and changes done to steps before the key frame won't affect steps after it.
     70
     71Turn keyframing mode on by clicking on the "Key" icon on the toolbar (1), then select the "Rotate Camera" icon (2). Now drag the mouse until you can see the bottom of the car from a good angle. If the car is not centered on the screen, you can also use the "Pan" and "Zoom" tools to adjust the camera.
     72
     73Once you get a good camera position turn keyframing mode off by clicking on the "Key" icon again and then add two black "Plate 2 x 2 with Wheels Holder" to the car:
    4674
    4775'''Picture goes here'''
     
    4977----
    5078
    51 Advance one more step on the project and let’s go to step 4. Select now the "Slopes" group (1), and choose the "Slope Brick 45 2 x 2", add one above the mudguard and another to the front of the car.
     79=== begin rewrite here ===
    5280
    53 Let’s also add another "Plate 1 x 4" to the car, you might not remember that it was the first brick you added but the program does so click on the arrow to the right of the search box (2) and you’ll see a list of bricks you have already used. You can select the "Plate 1 x 4" from there and save some time searching for it again. Here’s the picture of the almost complete car:

    59 There’s one thing missing in the car, the wheels so let’s use step 5 to add the wheel holders. It’s not going to be easy to see the bottom of the car from where we are so we’ll have to change our view position. We don’t want to make changes to the steps we did on the past so first click on the "key" icon on the toolbar (1) and then select the rotate camera icon (2). Now drag the mouse until you can see the bottom of the car from a good position. If the car is not centered on the screen, you can use the "Pan" tool to adjust it or you can Zoom in/out to make it better. Just select the tool you want to use, hold the left mouse button pressed and move the cursor.
    60 
    61 Now change the current color to black and add 2 "Plate 2 x 2 with Wheels Holder" to the car:
    62 
    63 '''Picture goes here'''
    64 
    65 ----
    66 
    67 Now all we need to do is add the wheels so go to step 6 and change the viewing position to a better angle. Add a gray "Wheel Centre" (select the first one from the list) and a black "Tyre" to the first wheel holder.
     82Now we can finally add the wheels to the car, so go to step 6 and change the camera position to an angle close to what we had on the first steps of the instructions. Add a gray "Wheel Centre" and a black "Tyre" to the first wheel holder.
    6883
    6984Change to the front camera by pressing the "F" key and zoom in, if you take a close look you’ll see that you can’t move the wheel to the correct place. That’s because the program is moving the bricks only to fixed places so turn 3D Snap off (1). Now select both the wheel and the tyre by choosing the "Arrow" icon (2) and clicking on the pieces while holding the CTRL key down and you’ll be able to move both pieces at the same time to the correct place.
