Create orthographic views of the given 3D object based on the provided dimensions.

Front view:

• Overall height: 75.0
• Base width: 25.0
• Step height: 15.0
• Step projection: 12.5
• Hole diameter: 20.0

Top view:

• Overall length: 60.0
• Depth: 40.0
• Section lengths: 20.0, 30.0
• Hole diameter: 20.0

Side view:

• Heights confirm 75.0, 15.0
• Length 60.0, depth 40.0
• Additional hole? 10.0

• Draw horizontal line for length (60.0 mm).
• Draw 30° lines for depth (40.0 mm) and height (75.0 mm).
• Scale: true lengths along axes; circles become ellipses (minor axis = diameter, major axis = diameter / \cos 30^\circ = diameter \times \frac{2}{\sqrt{3}}).

• Front face: parallelogram 25.0 mm horizontal $\times 75.0$ mm at 30°.
• Top face: extend 40.0 mm at -30° from top edge.
• Side face: extend 60.0 mm horizontal from side edge.
• Bottom face if visible.

• Block 12.5 mm horizontal $\times 15.0$ mm at 30° $\times 40.0$ mm depth.
• Align with front view step position.

• Main hole ($ø20.0$): ellipse centered per front/top views, visible on front and top faces.
  • Axes: minor 20.0 mm vertical, major $\approx 23.1$ mm at 30°.
• Second hole if present ($ø10.0$): similar, position per views.

Isometric view constructed with L-shape: vertical back $75.0 \times 60.0 \times 25.0$ mm, forward step flange $15.0 \times 30.0 \times 40.0$ mm approx., holes at specified positions.
