Tornado DWG Scanner after scanning 44 AutoCAD drawings: the report chain with its settings at the top, the results grid below with old DWG versions, missing xrefs and a missing font flagged in amber and red. — The report chain builds your columns. The grid below fills in as Tornado scans, with off-standard values flagged.

Hurricane changes drawings. Tornado reports on them.

Tornado is the sister tool to Hurricane, the batch script generator CAD teams have trusted since 2003. Where Hurricane makes changes across a whole drawing set, Tornado audits it: point it at a tree, filter to the problem drawings, and export the list. Load that list into Hurricane's Queue to fix them, then re-run Tornado to confirm the fixes cleared. The lists hand off both ways automatically.

Build your own report

Drag the checks you care about into a report chain and save it as a reusable recipe. 80 checks across 12 categories, tailored to what your AutoCAD install supports.

Enforce your standards

Set the expected value and a plain report becomes pass or fail: flag any drawing whose units, LTSCALE, DIMSCALE, plot style, current layer, or version is off standard.

Results you can act on

Sort and filter, click a row to open or reveal the drawing, see its preview, and export to Excel with the flag colors intact, or to CSV or JSON.
