It was the summer of 2002, and Leo Martinez thought he had finally tamed the beast. For three months, he’d been wrestling with AutoCAD 2002 on a refurbished Dell Precision workstation that wheezed like an asthmatic bulldog. The fan sounded like a leaf blower, and the CRT monitor hummed a low, ominous note that vibrated through his desk and into his bones.
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 .
> Stop drawing the ductwork in red. Red is for fire protection. You are not fire. Use cyan. Cyan is for air. It flows better.
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. AutoCAD 2002 Working
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.
He leaned back. The command line was blank. The cursor was just a cursor again.
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. It was the summer of 2002, and Leo
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.
Leo felt personally attacked by a piece of software. “Rude,” he muttered.
Leo typed: Thank you, Layer 0.
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.
Can you help me with the Albright ductwork?
> I've seen every mistake you've made. Your polylines have 47 extra vertices. Your blocks are nested seven layers deep. And you never, ever use object snaps properly. Leo froze
> Truth hurts. But yes. I can help. However. You must do something for me.
