ZUNAVI · 図ナビ Find, connect and reuse your drawings. Drawing management for manufacturers

Drawings, specs, parts and BOM in one ledger. Zunavi Scan reads the title block, you search by OCR full text, view in 2D and 3D, compare revisions, find similar parts and approve changes. On-premise first, because your drawings are confidential.

Illustration with sample data

Drawings live everywhere except where they should

The official PDF is on a file share, the latest revision is in an email, the approval happened on a phone call.

Which revision is current?

Revisions scatter across shares and inboxes, and someone is always working from an old printout.

Have we made this before?

Finding a similar part means remembering it, or asking the person who left.

Who approved this change?

Approvals happen by phone or chat and never reach the record.

One ledger that connects everything

Open a drawing and see its revisions, specs, parts, QR label and approval state together.

  • Search by drawing number, name, material, dimensions or full text (OCR).
  • Revision history with an active-revision switch.
  • Specs, documents and BOM linked to the drawing.
  • A QR label opens the drawing in the mobile app.

Register drawings without retyping

Zunavi Scan reads the title block in the corner of the sheet and fills in the ledger for you.

  • Reads drawing number, name, material, scale and revision from the title block.
  • AI-read values are flagged for confirmation, so a person approves every entry.
  • Works on the PDF and CAD output you already produce, with no manual data entry.

See exactly what changed between revisions

Overlay two revisions in 2D, or compare drawings side by side.

  • The 2D overlay highlights every difference.
  • Design changes (ECR/ECO) go through approval.
  • View each drawing as a page, 2D CAD or 3D.

Illustration with sample data

Open the 3D model next to the drawing

Switch any drawing between page, 2D CAD and 3D without leaving the screen.

  • Rotate the model and jump to standard views with the view cube.
  • Fit to screen or go full screen for a closer look.
  • The 3D shape is also what powers similar-part search.

Illustration with sample data

Find identical and similar parts before you draw a new one

Start from any drawing and see which parts already match in shape, material and size.

  • Spot identical parts across drawings so the same part is never drawn twice.
  • Match on 3D shape geometry, then narrow down by material and dimensions.

Assistive feature: accuracy is still improving and a person confirms every match.

On-premise first. Cloud when you want it.

Built for drawings that must not leave the building.

On-premise by default

Drawings stay inside your network. Cloud deployment is a supported option, not the default.

Nothing leaves without consent

Any feature that would send drawing data to an external service has its own consent switch.

Built for Japanese manufacturing

Japanese-first interface, and handling for legacy CAD encodings and DXF, DWG and STEP files.
