Confirm units, coordinate reference, origin, layer contents and a known dimension. Exported context is an early-design input; it does not establish a measured survey, legal boundary, heritage curtilage or complete constraint search. ## Introduction A useful CAD handoff carries both the geometry and enough information to interpret it. The file should be checked against the intended site and the evidence used to create it before it becomes the base for design drawings. This guide was reviewed against the repository’s export coordinate and validation code on 12 September 2026. It describes a verification workflow rather than promising identical layers, formats or export times for every site and account. ## Prepare the boundary and available context Locate the site and confirm the area intended for the export. Review which layers have loaded and whether their sources and dates are suitable. A visible map is not proof that every underlying feature is present in the exported file. Keep ownership boundaries, planning application boundaries and a user-drawn study area distinct. A terrain or building dataset is not a measured topographic survey. Mapped heritage records do not establish the legal curtilage of a listed building. ## Choose an available export and retain its settings Open the export controls available in the current product and choose DXF where offered. Check the account entitlement and the formats and settings actually shown. Retain any export summary, source information, coordinate setting and warnings. Do not assume a fixed layer inventory, contour interval or delivery time. If a layer is missing or a file is unexpectedly small, inspect the result and source coverage before continuing. The presence of a successful download alone is not a quality check. ## Check units and coordinates before combining files Open a copy in the target CAD application. Confirm the drawing units and compare a known dimension. Inspect the origin and coordinate system; local planar, latitude/longitude and projected coordinates are not interchangeable. Do not assume every export is British National Grid merely because the site is in Britain. Before combining the context with survey or consultant information, establish the agreed coordinate reference and any transformation. Check at least two identifiable locations as well as scale and orientation. Keep the original export unchanged so subsequent transformations are traceable. ## Inspect layers and geometry Review the layer list and turn layers on separately. Check the site extent, closed boundaries, overlapping lines, building footprints and any elevation information. Confirm that expected context appears in the file and that labels correspond to the intended features. Use separate layers for indicative context and verified survey information. Label limitations in the drawing package, especially where map boundaries or estimated heights could be mistaken for measured evidence. Avoid tracing a planning buffer as a definitive legal extent. ## Make a controlled design handoff Record the export date, site boundary, format, coordinate settings and checks performed. Identify unresolved discrepancies and the survey information that will replace early context. If the site area or source data changes, issue a revised context reference rather than silently overwriting the old drawing. The workflow can support early AutoCAD drafting, but compatibility with a particular version, imported entity type or other CAD application should be tested on the actual file. See [Atlasly’s methodology and limits](/blog/atlasly-site-analysis-methodology-and-limits) for the evidence boundary. ## Illustrative example Illustrative scenario: A team reopens an exported context file in its intended design application and checks units, two known distances, location and layer contents. Missing or altered elements are recorded before the file is used as a design reference. ## Frequently Asked Questions **Is an Atlasly DXF a measured survey?** No. Verify source accuracy and obtain an appropriate measured survey for decisions that depend on it. **Are exports always in British National Grid?** Do not assume that. Inspect the coordinate settings and metadata and confirm the target reference system. **Does the heritage layer show legal curtilage?** A mapped record alone does not establish legal curtilage. Review the listing and relevant evidence separately. **Will every layer or CAD format always be available?** Availability depends on the workflow, source coverage and entitlement. Inspect the actual export and test it in the target application. ## Conclusion Treat the export as a controlled context handoff. Check coordinates, units and features, retain source limitations and replace indicative information with verified survey evidence where the design depends on it. ## Related Reading - https://atlasly.app/blog/pre-construction-site-analysis-complete-guide - https://atlasly.app/blog/uk-planning-compliance-checker-architects - https://atlasly.app/blog/biodiversity-net-gain-2026-architects-guide-free-calculator - https://atlasly.app/blog/best-ai-tools-uk-architects-2026 ## Sources - [Planning Practice Guidance](https://www.gov.uk/government/collections/planning-practice-guidance) — GOV.UK - [Planning Portal](https://www.planningportal.co.uk/) — Planning Portal --- Source: https://atlasly.app/blog/how-to-export-site-context-dxf-autocad-atlasly Platform: Atlasly — AI site intelligence for architects, engineers, and urban planners. https://atlasly.app
