Export the current view as DXF
Choose File → Export Current View as DXF…, choose whether to omit hidden edges or export them as dashed lines, then choose Export DXF… and a destination. The hidden-edge choice is remembered between runs. The Japanese menu is ファイル → 現在の表示をDXFでエクスポート….
The drawing uses the camera when Export is pressed, including roll, the world's up axis and perspective. Only shown bodies are exported, at their current component/occurrence placements. Hidden bodies neither draw nor hide other bodies. The complete projected geometry is exported, including geometry beyond the viewport's edges. Grid, sketches, dimensions, selection highlights and other overlays are excluded. Turn off section analysis before exporting.
Coordinates are 2D, Z=0, in millimetres. Orthographic views retain 1:1 dimensions in the view plane. Perspective views retain foreshortening, projected onto the plane through the camera target; they are intended for illustrations rather than dimensioned fabrication. Curves and curved silhouettes are approximated with straight segments at a default model-space chord tolerance of 0.01 mm. This is not an exact analytic curve export.
The AutoCAD 2000 ASCII DXF contains VISIBLE (continuous) and, when requested, HIDDEN
(2 mm dashes / 1 mm gaps) layers. Hidden curves use connected LWPOLYLINE entities with
continuous linetype generation so the pattern does not restart on each chord. The pattern
is embedded in the file. The polyline flags follow the
Autodesk DXF reference.
Edges are split where another surface occludes them, including partial occlusion by another body. Hidden edges are never included in omit mode. Triangle diagonals and smooth seams are excluded; curved-body silhouettes are included. Very complex drawings fail with an error rather than returning an incomplete export. If geometry crosses the perspective camera's eye plane, zoom out before exporting.
Programmatic callers use file.export_view_dxf with camera: Camera, hidden: "omit" or
"dashed", optional tolerance (0.0001–1 mm) and optional path. Without path, the
command returns the DXF text. The command does not modify the design or its undo history.
