3 - Axle Holes & Supports

Welcome. You would have completed your model to this stage, thus far.

We will now insert the axle holes and support structures around them.

Create a New Sketch on the shown planar face in the rear wheel housing recess.

Select the Circle tool and Centre circle diameter from the Sketch menu.

Place a 6mm circle on the planar face/surface, as close to the centre as you can.

Select Sketch Dimension and position your circle centre 11.5mm from the top of your model (Y-axis), and 20.5 from one side.

This will position your axle hole centrally within the space.

These types of dimensions are called constraints, and they keep your geometry in place in case of accidental moving later on.

Repeat the process positioning the front axle at X167mm, Y10.5mm from the origin.

The axle hole is again 6mm in diameter.

Select the Extrude tool.

Select both circles using the Shift key.

Cut to a depth of -10mm.

Create a new sketch on the inner planar face of the wheel well recess.

Select the Centre Rectangle from the Create tab dropdown.

This is a special rectangle that is located around a centre point, such as the centre of the axle hole.

Create a Centre Rectangle at the centre of the axle hole.

The rectangle should be 14mm in width, and 12mm in height.

Use the Dimension tool to identify the second axle hole.

Place an identical Centre Rectangle over the front axle hole.

Click Finish Sketch

Extrude the axle supports outwards 2mm from the body.

Ensure the Extrude type is 'Join', and that the rectangles are 'joining' to the body, not 'cutting'.

Congratulations, you have completed this stage.
