Get a comprehensive high-level summary of a DXF CAD drawing. Returns: DXF version, units, layer count, block count, entity breakdown by type, total entities, and bounding box.

List all layers in a DXF drawing with properties (name, color ACI/Hex, linetype, lineweight, status on/frozen/locked, entity count).

List all block definitions and their usage/instance count in modelspace.

Query entities in the drawing with optional filtering by type (e.g. 'LINE', 'CIRCLE', 'LWPOLYLINE', 'TEXT', 'INSERT') and/or layer. Returns coordinates, dimensions, layers, and properties for each matched entity.

Extract all textual annotations, notes, and labels (TEXT & MTEXT) with exact coordinates, heights, rotations, and layers.

Create a new blank DXF CAD drawing file.

• dxf_version: e.g. 'R2018', 'R2013', 'R2010', 'R2007', 'R2000'

• units: 'mm', 'cm', 'm', 'in', 'ft', or 'unitless'

• layers: optional list of initial layers, e.g. [{"name": "WALL", "color": 1, "linetype": "CONTINUOUS"}]

Add a new layer or update an existing layer in a DXF drawing.

• color: ACI number (1-255), color name ('red', 'cyan', 'green'), or hex ('#FF0000').

Batch add geometric entities to a DXF drawing's modelspace.
Supported entity types:
- line: {"type": "line", "start": [x1, y1], "end": [x2, y2], "layer": "WALL", "color": 1}
- circle: {"type": "circle", "center": [x, y], "radius": r, "layer": "HOLES"}
- arc: {"type": "arc", "center": [x, y], "radius": r, "start_angle": a1, "end_angle": a2}
- lwpolyline: {"type": "lwpolyline", "points": [[x1, y1], [x2, y2], ...], "is_closed": true}
- rectangle: {"type": "rectangle", "corner1": [x1, y1], "corner2": [x2, y2], "layer": "FRAME"}
- text: {"type": "text", "text": "Label", "insert": [x, y], "height": 3.5}
- mtext: {"type": "mtext", "text": "Multi

Line", "insert": [x, y], "height": 3.5} - point: {"type": "point", "location": [x, y]} - ellipse: {"type": "ellipse", "center": [x, y], "major_axis": [dx, dy, 0], "ratio": 0.5} - dimension_linear: {"type": "dimension_linear", "base": [x, y], "p1": [x1, y1], "p2": [x2, y2], "text": "100mm"} - block_reference: {"type": "block_reference", "block_name": "DOOR", "insert": [x, y], "scale": 1.0, "rotation": 0.0}

Delete entities from a DXF file by handle list, or by layer/entity type filter.
