Connecting design and manufacturing: from drawings straight to the shop floor
We build custom software for manufacturing, CAD/BIM design, and GIS. By automating parametric modeling, sheet metal nesting, and smart BOMs, we help engineering teams cut repetitive rework and deliver accurate data directly to production.
Software that fits into how engineers actually work
We start from drawings, models, production handoffs, and fabrication constraints — then build the automation around them.
Core technical capabilities
CAD platforms, BIM and 3D engineering, mechanical CAE, spatial data, engineering AI, and system integration from design to validation.
Manufacturing & Fabrication
From engineering drawings straight to the shop floor. Parametric model updates, automated nesting, and smart BOMs eliminate manual data re-entry and deliver production-ready cutting paths directly.
Partner Ecosystem
We keep an open engineering software ecosystem and connect domestic and international CAD/BIM toolchains with care.

CAD
BIM / 3D
CAE / MFG
GIS
AI / Integration
Groundwork First, Long-Term Delivery
We test real drawing constraints and shop floor limits before deployment, ensuring tools enter daily production rather than staying as fragile demos.
Understand the workflow
Mapping drawing flow, modeling, calculations, and handoffs to pinpoint what saves the most engineering hours.
Validate with prototypes
Testing core algorithms against real production drawings and models to uncover edge cases and tolerances early.
Deliver and maintain
Delivering native plugins or standalone tools with clean packaging and version upgrades that keep pace with CAD/BIM platforms.
Frequently Asked Questions
Quick answers about scope, collaboration, and delivery boundaries.
Both, and they are clearly separated. /products lists ready-made tools you can download or try, while /solutions covers what we build for specific engineering workflows.
CAD: AutoCAD, ZWCAD, GstarCAD, BricsCAD. BIM and 3D: Revit, MicroStation, Unity3D, Unreal. GIS: ArcGIS, SuperMap, QGIS, GDAL, GeoServer, PostGIS.
We use AI only where there is a verifiable engineering task — drawing translation, order parsing, form automation, quantity takeoff, BOM generation. It is not a selling point on its own.
Confidential, defense, and internal customer projects are strictly anonymized. Case studies display only information cleared for public disclosure.
Bring us the workflow you want to improve
From repetitive drafting and BIM drawing output to CAE parametric work, GIS data processing, AI forms, and quantity takeoff, we help assess the practical software path.
