QA Checker

Beta — for testing

Check a drawing

Upload a DXF drawing and VerifyCAD will review it against standard CAD good practice and your own standard if you set one up.

What VerifyCAD checks

Always checked (no setup needed)

These run on every drawing automatically:

  • Content on reserved layers (Layer 0, Defpoints)
  • Duplicate tags — for P&ID and schematic drawings, where tags must be unique
  • Blank title block fields — drawing number, revision, date, drawn-by, checked-by (when a title block is found)
  • Drawing number not matching the filename
  • Degenerate geometry — zero-length lines, zero-size circles/arcs, collapsed polylines
  • Empty text — text boxes with nothing in them
  • Blank or default-named layers (e.g. “Layer1”, “New Layer”)
  • Placeholder notes left in — TBC, TBD, XXX, ???, “confirm”

Checked against your standard (when you set one up)

Set up your standard (upload a template or enter it manually) to also check:

  • Layer names against your approved list
  • Approved blocks / symbols against your library
  • Text styles, fonts and heights
  • Tag formats against your approved patterns
  • Line weights, linetypes and colours per layer (available, but off by default — real drawings often have deliberate per-entity overrides, so this is optional to avoid false alarms)

Nothing is changed in your drawing — VerifyCAD only flags, it never edits. BETA: we’re adding more checks over time.

  1. 1Set up your standard — upload your template drawing (recommended) or set it up manually.
  2. 2Choose your drawing type.
  3. 3Upload your DXF drawing and run the check.
  4. You'll get a report of any issues found — nothing is changed in your drawing.

Step 1 — Set up your standard

Upload your template drawing and we'll read your layers, text styles, linetypes and blocks automatically — or set your standard up manually using the form. Optional, but it gives you much deeper checks.

Set up your standard

Optional

Optional — you can skip this and go straight to uploading a drawing. Setting up your standard gives you deeper checks. Anything you enter stays in this browser session only.

Upload your template (recommended)

Uploading a template DXF auto-fills the structural parts of your standard — layers, text styles, linetypes and blocks. You can review and adjust everything in the manual section below.

How to get a DXF from your template

Your template is probably a DWG or DWT — here’s how to export a DXF:

  • AutoCAD: type SAVEAS, choose ‘AutoCAD DXF’ as the file type, and save.
  • Other CAD software (DraftSight, BricsCAD, etc.): use File → Save As and choose DXF.
  • No CAD software? The free ODA File Converter (opendesign.com) converts DWG to DXF on your computer.

Your files stay on your machine — you’re just saving a DXF copy to upload.

Set up or review manually

Build your standard from scratch, or adjust what the template extractor filled in.

Optional

Layers

The layers your drawings should use, and how each one should be set up.

Tag formats

How tags should be written. Give an example and build the pattern — we’ll tell you if they match.

Text styles

The text styles and heights your drawings should use.

Approved blocks

Block names that are allowed in your drawings. Anything else is reported.

Duplicate tags

How repeated tags should be treated in your drawings.

No two entities within the same drawing may share an identical tag. Cross-drawing duplicates (a tag reused across sheets in error) are flagged for manual review rather than auto-failed.

Advanced: see the rules file

You never need to look at this — it’s what gets sent with your drawing.

Step 2 — Choose your drawing type

So we apply the right checks — e.g. tag-uniqueness checks apply to P&ID and schematic drawings.

3

Step 3 — Upload your DXF drawing and run the check

Your drawing is checked against standard CAD good practice, plus your own standard if you set one up.

How to get a DXF file

VerifyCAD reads DXF files. If your drawing is a DWG, here’s how to export a DXF:

  • AutoCAD: type SAVEAS, choose ‘AutoCAD DXF’ as the file type, and save.
  • Other CAD software (DraftSight, BricsCAD, etc.): use File → Save As and choose DXF.
  • No CAD software? The free ODA File Converter (opendesign.com) converts DWG to DXF on your computer.

Your files stay on your machine — you’re just saving a DXF copy to upload.
