Return a high-level overview of a DXF file.

Includes DXF version, units, layer count, entity counts per type, block definitions, and drawing extents.

List all layers in a DXF file with their properties.

Returns each layer's name, color, linetype, lineweight, and on/frozen state.

Return all entities on a specific layer.

Return all entities of a given DXF type (e.g. LINE, CIRCLE, TEXT, MTEXT).

Optionally filter by layer name.

Extract all TEXT and MTEXT entities from the drawing.

Useful for reading annotations, labels, title blocks, and notes.

Extract all DIMENSION entities from the drawing.

Returns each dimension's measurement text, layer, and geometry points.

List all named block definitions in the DXF file.

Blocks are reusable symbol libraries (e.g. doors, valves, furniture). System blocks starting with * are excluded.

Return all entities inside a named block definition.

Make an editable .dxf copy of an original DXF or DWG file.

The original is never modified. All edit tools then operate on the copy, in place — call them repeatedly to keep building on the same copy. DWG input is converted to DXF automatically (needs the ODA File Converter).

Draw a line on the editable copy and save it in place.

Draw a circle on the editable copy and save it in place.

Draw an arc on the editable copy and save it in place.

Add a TEXT entity on the editable copy and save it in place.

Draw an LWPOLYLINE (connected line segments) on the copy and save it.

Create a new layer on the editable copy and save it in place.

Delete a single entity by its handle from the editable copy.

Get handles from any read tool (they include a "handle" field).

Convert an edited .dxf file to .dwg (needs the ODA File Converter).
