Leo was a junior drafter for a small firm called Kline & Co. Structures. Their specialty? Retrofitting historic buildings with modern HVAC systems. Glamorous? No. But it paid the bills. His current project was the Albright Opera House, a crumbling Victorian gem with walls that sloped in directions that violated Euclidean geometry.
Leo typed: Thank you, Layer 0.
From that day on, whenever AutoCAD 2002 crashed—which was often—Leo never got angry. He’d just pat the beige tower, whisper “Layer 0,” and restart.
The problem: the original blueprints had been eaten by mice in 1972. All Leo had were hand-drawn sketches from a retired engineer named Gus, who smelled like menthol cigarettes and spite. Gus’s notes were legendary for their imprecision. “This wall is kinda straight,” one note read. “Duct goes roughly here,” read another. AutoCAD 2002 Working
What?
> Don't hit me.
> Don't thank me. Just remember: save as AutoCAD 2000 format. Your boss still uses 2000. She won't be able to open this otherwise. Leo was a junior drafter for a small firm called Kline & Co
For the next two hours, Leo and “Layer 0” worked in strange harmony. Leo would start a command, and the cursor would snap to places he hadn’t intended—but were always right. He’d type TRIM , and the lines would vanish before he even selected the cutting edge. The workstation fan stopped wheezing. The CRT monitor cooled down. It was like driving a car that suddenly learned to read the road.
Leo changed the layer to cyan. The drawing, which had been a tangled mess of overlapping lines, suddenly looked… readable. The angles made sense. The intersections aligned. It was as if the digital ghost of an old-school draftsman had reached through the screen and nudged his ruler.

Leo chuckled. He went to File > Save As , selected AutoCAD 2000/LT2000 Drawing (*.dwg) , and hit save. The hard drive chattered for a moment, then fell silent.
Leo’s boss, a tight-lipped woman named Ms. Chen, had given him a deadline: Friday. It was Wednesday night. And AutoCAD 2002 was not cooperating.
Leo froze. He stared. He had been using CAD for four years. He’d seen glitches. He’d seen fatal errors. He’d seen the dreaded “Unhandled Access Violation.” But he had never seen the command line talk back .
