DXF export for reviewed survey linework

SurveyMarkup prepares feature-coded linework for DXF handoff and runs advisory checks first — codes, geometry and CRS metadata — so issues surface before the file reaches a drafter. The DXF is a reviewable working file, not a survey deliverable.

Advisory only

Advisory and unverified — not for survey deliverables. A registered surveyor must confirm any output before it is relied on.

What SurveyMarkup can flag or organise

  • Codes that are missing before export
  • Geometry worth a manual check
  • CRS metadata mismatches

What it cannot prove or certify

  • It does not certify the DXF or its geometry
  • It does not verify coordinate correctness
  • It does not replace CAD drafting review

Why a review step before DXF handoff

Missing codes, stray geometry or a CRS mismatch are cheaper to fix before a file lands in CAD. A short advisory review keeps handoffs clean.

  • Feature codes mapped to layers
  • Geometry sanity prompts
  • CRS metadata surfaced for review

Feature-coded layers for drafting

Linework is organised by feature code so the receiving drafter gets structure, not a flat dump. You stay in control of what the codes mean.

Limitations

DXF export is an advisory handoff aid. It does not verify coordinates, certify the drawing, or replace a drafter's review in AutoCAD, Civil 3D or 12d.

Worked example · synthetic

Coded linework is prepared for a DXF handoff to a drafter in AutoCAD.

What SurveyMarkup surfaces

  • Feature codes mapped to layers for review
  • A zero-length line and a duplicate point
  • CRS metadata surfaced before export

Reviewer's call: The drafter opens the DXF, confirms layers and geometry, and treats it as a reviewed working file — not a survey deliverable.

Frequently asked questions

Will the DXF open in AutoCAD or Civil 3D?

The export targets standard DXF for review and handoff. Treat it as a working file and confirm it in your CAD package before any professional use.

Are the exported coordinates verified?

No. Coordinates remain unverified. The export is an advisory handoff file that a registered surveyor must confirm.

Does this replace my drafter?

No. It is a pre-handoff review aid, not a drafting or certification tool.
