How to Export Site Context to DXF for AutoCAD Using Atlasly

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.

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.

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.

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.

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 for the evidence boundary.
