Initial Setup: Before we start, please ensure that you grid settings are as follows:

• Major Grid spacing: 50mm

• Minor Subdivisions: 5

To change these at any time you can go to the 'Grids and Snaps' tool on the bottom toolbar, then 'Grid Settings'.

Step 1: Press the R key on your keyboard to enter the RECTANGLE command.

Select the plane that you would like to start sketching on. In this instance we will use the XY plane (the floor).

Step 2: Draw a 2-point rectangle.

Left-click where the green and red lines overlap to place the first corner of your rectangle.

Drag out and enter a dimension of 200 mm for the width. Press tab to move to the height and add a dimension of 150 mm for the height.

Alternatively, count 20 squares wide (X) and 15 squares high (Y) on the grid and then left-click again (the dimensions should be 200mm x 150mm)

Tip: You may find that the edges of your rectangle extend out of your screen and that you may need to select the ‘fit’ button to fit the rectangle within your screen.

Step 3: Press the E key on your keyboard to enter the EXTRUDE command.

Select the rectangle you created in step 3. Enter a dimension of 3mm.

You have now created the chassis blank.

Step 4: Now we will create cutouts in the chassis for wheels.

Press the R key on your keyboard to enter the RECTANGLE command and select the top face of the chassis blank.

This will change the view to the top view (plan view).

Starting 4 squares from the bottom left corner, use the grid squares to measure a rectangle that is 5 squares wide and 2 squares tall (50 mm wide and 20 mm tall).

Repeat this process one square from the bottom right corner (you will notice a green dashed line that indicates the shapes are aligned).

Step 5: Repeat this process on the other side of the chassis. Please note that the rectangles will ‘snap to grid’.

Complete this stage by selecting ‘stop sketch’.

Step 6: Press the E key on your keyboard to enter the EXTRUDE command.

Select the four rectangles that you have just drawn. Enter a dimension of -3mm and press Enter to complete the cut-outs.

Step 7: We are now going to add an arc to the front of the vehicle. Click on the sketch icon and select the top of the vehicle chassis.

Select the 'Create' dropdown menu > Select Arc > Select 3-Point Arc

Select the corner of the wheel cutout. as shown > Select the second corner of the wheel cutout as shown

Place the arc on the centre point as indicated with a green cross > Left-Click to place the arc.

Press 'Stop Sketch' to complete the arc.

Step 8: Press the E key on your keyboard to enter the EXTRUDE command.

Select the material on the outside of the arc > Enter a dimension of -3mm

Press Enter to remove material.

Step 9: Press the C key (Hot-Key) on your keyboard to create a CIRCLE from a center point.

Navigate to the side of the vehicle chassis > Select the inside edge of the cutout for the wheel.

Use the green guideline to help you select the very center of the wheel cutouts.

Place the center of the circle and then select a size of 2mm > Press Enter > Press Stop Sketch.

Step 11: Press the C key (Hot-Key) on your keyboard to create a CIRCLE from a center point.

Repeat the circle process to draw a new circle on the end of the axle. The new circle should measure 40mm in diameter.

Step 12: Press the E key on your keyboard to enter the EXTRUDE command.

Extrude the circle that you drew in step 11 by a distance of 10 mm.

Step 13: Press the O key on your keyboard to enter the OFFSET command.

Select the cylinder (then circle) that you created in Step 12 and then drag the handle inwards to create a new parallel shape inside. Press Enter.

Size should be between around -10 mm but is not vitally important.

Step 14: Press the E key on your keyboard to enter the EXTRUDE command.

Extrude the circle that you drew in step 6 by a distance of -5mm. Press Enter.

Step 15: Select the CONSTRUCT drop-down menu and then select MIDPLANE.

Select the one side of the chassis.

Select the ORBIT tool from the navigation menu at the bottom of the page.

Left-click and hold the button down anywhere on the screen. Move your cursor or trackpad to spin the model around. Press escape to exit the orbit tool.

Select the other side of the chassis.

Press enter to complete the midplane.

Step 16: Select the CONSTRUCT drop-down menu and then select MIDPLANE.

Select the inside-left face of the first cutout.

Select the ORBIT tool from the navigation menu at the bottom of the page.

Left-click and hold the button down anywhere on the screen. Move your cursor or trackpad to spin the model around. Press escape to exit the orbit tool.

Select the inside-right face of the last cutout.

Press enter to complete the midplane.

Step 17: Expand the Bodies tab and select the axel and wheel.

This should be body 2.

Step 18: With Body 2 still selected, go to the CREATE dropdown menu and select MIRROR.

From the mirror options window, click on the mirror plane select arrow.

Select the midplane you completed in step 15 to complete the mirroring process.

Step 19: Expand the Bodies tab and select Bodies 2.

Hold the CTRL key and also select Body 3.

Step 18: With Body 2 and Body 3 still selected, go to the CREATE dropdown menu and select MIRROR.

From the mirror options window, click on the mirror plane select arrow.

Select the midplane you completed in step 16 to complete the mirroring process.

Step 19: We will now draw a new rectangle on the back of this chassis.

Start by pressing the letter ‘R’ to activate the RECTANGLE tool. Select the top surface of the chassis that we just created > Draw a new rectangle towards the back (between the back wheel arches).

Step 20: Press the E key on your keyboard to enter the EXTRUDE command.

Select the four rectangles that you have just drawn. Enter a dimension of 50 mm and press enter.

Step 21: Select the MODIFY drop-down menu and select CHAMFER.

Step 21: Select the top two corners of the cuboid created in step 20.

Enter a dimension of 15mm, or similar.

Step 7: Now we will create a cutout in this new shape using the Offset tool.

Press the letter ‘O’ and select the rear face of the shape we have created > Select the outside line > Enter the dimension – (minus) 3mm > Press Enter > Finish the sketch to return to the isometric view.

Step 8: Press the E key on your keyboard to enter the EXTRUDE command.

Drag the arrow backwards to remove the internal part of the shape.

Extension task: Press the A key on your keyboard to enter the APPEARANCE command.

Select the paint material from the list and drag this directly onto the model.
