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 remains a professional decision
- It does not professionally sign off the DXF or its geometry
- It does not establish 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 establish coordinates, professionally sign off 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 confirmed?
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 professional sign-off tool.
