     3This tutorial is designed to show you the basics of LeoCAD. You will learn how to browse the pieces list, add pieces to a model, move and rotate pieces, create a model with multiple steps and change the camera position.  Through these exercises, you will create a race car and driver.

    5 To do that we'll create a racing car and driver. First, start the LeoCAD application. You should see a window that looks like this:
     5Keep in mind that the user interface is different between Operating Systems, so if you're not running the MS Windows version of LeoCAD your screen may differ slightly from what's shown here.

    9 LeoCAD presents a standard user interface: a titlebar, menus, and toolbars at the top, a status bar along the bottom, and a workspace and tool-windows in the center. The large square white area to the left is the main drawing area, where one or more views of your model are displayed. To the right is a tool window showing a list of available pieces, with a picture of the currently selected piece and a palette of available colors. There are additional tool windows available for other operations, but they won't be featured in this tutorial.

     11LeoCAD presents a standard graphical user interface: a titlebar, menus, and toolbars at the top; a status bar along the bottom; and a workspace with tool-windows in the center. The left-hand portion of the workspace area is where one or more views of your model are displayed. To the right is a tool window showing a list of available pieces, with a picture of the currently selected piece and a palette of available colors. There are additional tool windows available for other operations, but they won't be featured in this tutorial.

    15 Start the model by adding a blue 1x4 plate.  First, expand the "Plates" category in the pieces list (alongside the right edge of the screen by default) by clicking on the [+] icon next to "Plates". Then scroll down and select "Plate 1 x 4". Next click on the blue rectangle in the color palette near the bottom right of the screen to set the current color to blue. Notice that the image in the top right corner changes as you select pieces or change colors, to reflect your current choice.

    17 Now add the brick to the drawing area: Click the Insert [[Image(brick_icon.png, nolink)]] tool.  It's located on the drawing toolbar, which by default is docked near the upper left of the LeoCAD application window. The mouse cursor will change to the insert image [[Image(brick_icon.png, nolink)]] to indicate Insert Mode. Move the mouse over the drawing/view area, and click the left mouse button to add the new piece to the model. Alternatively, you can press the Insert key to add a new piece, or you can drag it from the piece list and drop it in the drawing area.
     17First, expand the ''Plate'' category in the pieces list (by default, this is displayed along the right edge of the workspace) by clicking on the [+] icon next to ''Plate''.

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 [wiki:CoordinatesDisplay X/Y/Z location] of the currently selected brick is shown on the lower right corner.''

    25 Next, select "Plate 2 x 4" from the list of pieces to add it next to the first piece. After you add a piece the mouse cursor changes to an icon that looks like four arrows [[Image(arrow_icons.png, nolink)]], that means that if you now keep the mouse button pressed and move the cursor the objects that are currently selected will be [wiki:MovingPieces 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.

    35 We 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".
     40Step 3: Add a blue 2x8 plate in a new step

    37 Since 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 [[Image(next_step.png, nolink)]] 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.

    39 Add 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 [wiki:RotatingPieces rotate] it until it's in the correct position. Select the "Rotate" icon from the toolbar [[Image(rotate_piece.png, nolink)]], the cursor will change and then drag the mouse until the brick is rotated 90 degrees.
