Perfect orthographic front elevation of a modern sliding steel gate, total width 350 cm and height 200 cm, with a 6 cm thick rectangular steel frame.
On the left side, there is a sequence of vertical raised steel slats (3 cm deep) with these exact widths (in this order):
• 2 slats of 7 cm
• 2 slats of 6 cm
• 3 slats of 5 cm
• 3 slats of 4 cm
• 4 slats of 3 cm
• 4 slats of 2 cm
Each slat is separated by a 2 cm gap.
After this slat section, the remaining right side is a flat solid steel panel.
All slats must be clearly different in width, visibly decreasing, and precisely spaced.
The image must show a perfectly flat, straight-on orthographic front view, with no perspective, no vanishing point, no depth distortion — as in a technical architectural elevation drawing.
Material finish: dark antique matte gray steel with soft, even lighting, neutral plain background, and no visible shadows.
