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 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.
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.
