| Challenge | Cause | Solution | |-----------|-------|----------| | | XML converters see blocks as groups of lines, not smart objects | Use FME or AutoCAD's DATAEXTRACTION to export block attributes to CSV, then convert CSV to XML separately. | | Curves become faceted lines | XML schemas like GML require straight segments | Increase arc resolution in export settings (e.g., set chord tolerance to 0.001 units). | | Coordinate system mismatch | DWG uses local coordinates; XML expects WGS84 | Reproject using FME, GDAL ( -t_srs EPSG:4326 ), or AutoCAD's GEOGRAPHICLOCATION command. | | Huge file sizes | XML is verbose; every coordinate is in plain text | Compress XML (GZIP) for storage, or convert to a binary XML variant like EXI. | | Missing layer information | Converter ignored layer tags | Verify that your converter supports layer extraction. GDAL requires -skipfailures flag to capture layers. |
A dialog box titled "Export to LandXML" appears. Navigate through the tabs: convert dwg to xml
