One command. Scan your drawing. Get a score out of 100 — and fix it in one click.
When you receive a drawing from a consultant, or before you submit your own — do you actually know how clean it is?
Receive drawing from contractor
→ Messy layers, unpurged blocks, objects on Layer 0
→ File keeps getting larger, slower, unstable
→ No idea what's wrong or what to fix first
→ Run PURGE once, not sure if it did anything
AutoCAD's built-in AUDIT and PURGE are single-point fixes. Nobody has ever put a score on the whole thing. You can't answer: how healthy is this drawing?
Type DHS. A diagnostic dashboard pops up:
- Overall score 0–100 — know the health of a drawing instantly
- 8 individual checks — see exactly what's wrong and how bad it is
- Check the fixes you want, click Run Fix Now — runs silently in the background
- Auto re-scans after fixing — shows exactly how many MB were saved
- Download
DrawingHealthScore.lsp - In AutoCAD, type
APPLOAD - Load the file
- Type
DHSto run
Tip: Add it to AutoCAD's Startup Suite for automatic loading every session.
Type DHS. The dashboard opens automatically after scanning.
The window shows:
- Top: Overall score and status
- Middle: 8 diagnostic results with [GOOD] / [WARN] / [FAIL] labels
- Bottom: Fix options with checkboxes — click Run Fix Now to execute
After fixing, the tool re-scans automatically and shows before/after comparison with MB saved.
