Everything Tornado checks
Build a report from 80 checks across 12 categories. Tornado runs your AutoCAD engine on each drawing, so the results are the real thing, not a guess from the file header. A check your install cannot run is shown grayed out with the reason.
The checks, by category
File and standards
DWG version, file bloat, edit time, drawing properties, custom properties (pull one, such as a project number, into its own column), password and digital-signature flags, units, INSUNITS, LTSCALE, DIMSCALE, plot-style mode, current layer.
Layers
Layer count and table, empty layers, objects on layer 0, non-standard names against your list, frozen / off / locked states, xref-dependent layers.
Blocks and attributes
Insert counts, title-block attribute extraction (your drawing register), all attributes of a block, dynamic, nested, anonymous, and unresolved blocks.
Xrefs and underlays
Attached count, every xref with its path, attach or overlay and nesting depth, missing references, circular references, absolute versus relative saved paths, PDF, DGN, DWF and raster image files and which are missing.
Text and fonts
Text and MText counts, text styles with their fonts, missing SHX, big font and TrueType fonts, and a full text dump you can search for a note, tag, or spec reference.
Dimensions and annotation
Dimension styles (and which are in use) and counts, wipeouts, revision clouds, exploded dimensions, annotation scales and how many objects use each, multileader styles, fields (including ones showing ####), hyperlinks.
Layouts and plotting
Page setups with paper size and plot scale, plot styles and named plotters (flagged when a layout has none or the file is missing), every viewport with its scale (odd scales flagged), named views.
Entity census
Total count, count by entity type, proxy objects that plain AutoCAD cannot edit, zero-length junk geometry, 3D objects.
Geometry and takeoffs
Line length and area by layer, hatch area by layer, and block quantity by block and layer, the quantity-takeoff hook.
Health
Read-only AUDIT errors, a purge preview (unreferenced blocks, layers, linetypes, styles), hard-coded properties, non-standard text styles, drawing compare against a baseline folder, and recovery flags.
What makes it an auditor, not just a reporter
Report chains and recipes
Drag checks into a chain, set each one's options, and save the whole thing as a recipe you reuse on every project.
Tunable standards
Most checks take an expected value or a threshold. Set your office standard once and Tornado flags every drawing that misses it.
Flag rules
Color any cell amber or red on your own conditions (greater than, missing, duplicate, and more), then filter the results to just the offenders.
Adapts to your AutoCAD
A one-time capability probe tailors the available checks to exactly what your installed AutoCAD version can do.

Search and filter
Find text across a set, count a single entity type, or list only blocks used at least N times.
Rows your way
One row per drawing, per layer, or per xref. Explode any list check (layers, blocks, attributes, viewports, page setups) into one row per item.
Standards and baselines
Check every drawing against your office standard, saved once as a recipe, or compare a set against an earlier issue to see what changed.
Exports
Save the current view to Excel with the flag colors intact, or to CSV or JSON, ready for a submittal or a QA record.
See it in action
Compose the report, then tune it
Drag the checks you care about into a report chain, in the order you want the columns. Most checks carry their own options right on the card: an expected value that turns a plain reading into pass or fail, or a threshold that decides when a number is worth flagging. Save the whole chain as a recipe and every project starts from your standard, not a blank sheet.
Flag the drawings that break your rules
On top of the built-in standards checks, add your own flag rules: color any column amber or red when a value is greater than, missing, duplicated, or off an expected setting. The grid lights up the drawings that need attention, and the Flagged view hides everything that passed. Export keeps the colors, so a reviewer sees exactly what you saw.
Drawing Explorer: open one drawing and look inside
Batch reporting tells you which drawings are odd. The Drawing Explorer tells you why. Open any single drawing, from a results row or on its own, and Tornado reads it live into six views:
- Blocks: every block with its insert count, attributed title blocks first. Expand one to see every instance, with its layer, layout, position and its own attribute values. Dynamic blocks show under their real names.
- Layers: color, linetype, lineweight, state, and how many objects of each type sit on each layer.
- Xrefs and files: xrefs with their saved paths, nesting and attach or overlay, plus raster images and PDF, DGN and DWF underlays, each marked found or missing.
- Layouts: page setups (plotter, plot style, paper, scale) and every viewport with its scale, lock state and frozen layers.
- Styles: text styles with their fonts (missing ones marked), dimension, multileader and table styles, and linetypes, each marked used or unused.
- Drawing: units, extents, key settings, dates, drawing properties, custom properties, and object counts by type.
Search across the view at once, export any view to CSV, and reopen a drawing instantly (Refresh reads it again). It is also the fastest way to build a report. Found the title-block tag, the layer or the custom property you were hunting for? Click the plus and Tornado drops a pre-filled check into your report chain, so you go from discovering a value to auditing it across the whole set in one step.
Export the report, and the file list
When the report is right, export the current view exactly as you see it, sorted and filtered, to Excel with the flag colors intact, or to CSV or JSON for a submittal or a QA record. You can also export just the file paths as a list, ready to hand to Hurricane.
The Hurricane loop
Audit a tree in Tornado, filter to the problem drawings, and export a file list. Load that list into Hurricane's Queue to batch-fix them, then re-run Tornado on the same list to confirm the fixes cleared. Tornado finds Hurricane's file-list folder automatically, so lists hand off both ways with no folder hunting.
