| Tool | What It Shows | |------|----------------| | | Total RAM usage, AutoCAD process memory | | Resource Monitor | Hard faults/sec (high = paging to disk = slow) | | RAMMap (Sysinternals) | Standby memory, page table usage | | PERFMON (Windows) | Track Available MBytes over time | | AutoCAD’s STATUS command | Shows DWG size, objects, but not RAM – use (ver) + (mem) in LISP | autocad low memory

| Component | Memory Impact | |-----------|----------------| | | Entities, layers, blocks, dictionaries | | Undo/redo history | Can consume 3–5x the DWG size | | Object enablers | Custom objects (Civil 3D, MEP) | | Regen data | Viewport display lists | | Xrefs & images | Each attached file loaded separately | | Palettes & UI | Properties, tool palettes, DesignCenter | | Plugins (LISP, .NET, VBA) | Can leak memory over time | AutoCAD doesn’t fail because it’s “bad software” –
