How do you draw a furnace on a workbench?

To draw a furnace on a workbench, start by sketching a rectangular or square shape to represent the furnace body, adding details like a door and vents. Next, illustrate the workbench beneath, ensuring it has sturdy legs and a flat surface. Include tools and materials around the furnace, such as metal scraps or a hammer, to enhance the scene. Finally, add shading and texture to give depth and realism to both the furnace and the workbench.
