Why 20,000 as the upper limit? This is a legacy soft-cap built into many of AutoCAD’s array, tiling, and segmentation functions. While modern computers can technically handle more, Autodesk engineers determined that 20,000 iterations of most command operations (like copying in a polar array or dividing a line) is the practical performance ceiling before the software becomes unstable or the file size becomes unmanageable. Most AutoCAD errors reference geometry ("line not closed") or objects ("no selection set"). This error is different. It feels modal and numerical . It interrupts your spatial, visual workflow and forces you into a pure mathematical mindset. You aren't thinking about your building elevation anymore; you are wondering, "What number did I accidentally type three commands ago?"
If you have spent any significant time drafting in Autodesk AutoCAD, you have likely encountered a moment of frustrating confusion. You are in the flow, typing a command, entering a coordinate, or setting a parameter, when suddenly the command line barks back: autocad please enter an integer from 1 to 20000
A: Create multiple arrays. For example, two arrays of 15,000 instead of one array of 30,000. Or use a dynamic block with a pattern. Why 20,000 as the upper limit
