QISMACAD // PRO
3.0.0-dev [DEVELOPMENT_BUILD]
INTEROPERABILITY SPECIFICATION // I/O ARCHITECTURE

Comprehensive Format & Data Interoperability

Detailed entity coverage, cadastral libretto parsing, and openBIM schema compliance across technical standards.

CAD Standards: DXF & DWG Specifications

Bi-directional drafting interchange and native binary parser architecture.

IN DEVELOPMENT

AutoCAD® DXF (ASCII & Binary)

Support designed across R12 through R2018 specifications with layer mapping and RGB 24-bit color fidelity.

Supported Entities: LINE, POINT, CIRCLE, ARC, LWPOLYLINE, POLYLINE (2D/3D), 3DFACE, TEXT, MTEXT, SOLID.
IN DEVELOPMENT

Native Autodesk® DWG™ Parser

Native Rust reader under active development. Parser coverage testing conducted across historical R14-R2024 drawing specifications.

Development Notice: Coverage testing in progress on 3D ACIS solids and complex proxy entities. Export functionality planned for future release.

Topographic & Cadastral Formats

Precision surveying instruments, total station libretto parsing, and point clouds.

IN DEVELOPMENT

Italian Cadastre Pregeo DAT

Deterministic parser for Italian land agency libretti with direct trigonometric fiducial coordination (TAF).

Parsed Row Types: Row 1 (Instrument station), Row 2 (Target angles & slope distances), Row 7 (Boundary lines & parcels), Row 8 (TAF coordinates).
IN DEVELOPMENT

Point Cloud (ASCII XYZ / CSV)

High-speed streaming parser for coordinate text streams (X, Y, Z, Intensity, Class code). Binary LAS/LAZ planned.

Infrastructure & openBIM Standards

Terrain surface meshes, parcel alignments, and buildingSMART IFC schemas.

IN DEVELOPMENT

LandXML (v1.2)

Support designed for TIN surface definition (<Surfaces>), boundary lines, and parcel alignments (<Parcels>).

IN DEVELOPMENT

openBIM® IFC (IFC4 & IFC4x3)

Spatial site structure export: IfcProject, IfcSite boundary, and faceted boundary representation (IfcFacetedBrep) for DTM terrain models.
