Dirac

CAD-to-build automation for manufacturing

Overview

Dirac builds BuildOS, an AI manufacturing platform that converts CAD files into executable work instructions, MBOM, and bill of process. Engineers upload design files and get proposed assembly order, 3D step animations, and production-ready build content faster than manual authoring, then refine the remaining details for the shop floor. Operators follow versioned digital instructions at the station while teams capture performance feedback and maintain a single source of truth across instructions, routings, BOMs, quality, and tooling. BuildOS is used in aerospace and defense, industrial equipment, agriculture and construction machinery, and other complex manufacturing environments where precision and repeatability matter. Customers range from suppliers to OEMs that need design intent translated into consistent execution. Business model is B2B SaaS for manufacturing engineering and production teams. Official website is diracinc.com and brand is Dirac for CAD-to-build automation.

Simplify's take

What believers are saying

  • Anduril cut work-instruction authoring 87.5% and is rolling BuildOS companywide in 2026.
  • Dirac launched Azure Marketplace availability in August 2026, unlocking budgeted enterprise procurement.
  • AWS GovCloud support and ITAR handling open defense programs that reject generic SaaS tools.

What critics are saying

  • Anduril enterprise rollout risks platform dependency if its 2026 deployment stalls or changes vendors.
  • Microsoft and AWS partnerships deepen distribution, but also let hyperscalers disintermediate Dirac's software layer.
  • If CAD-to-instruction accuracy breaks on a major program, aerospace customers will abandon BuildOS quickly.

What makes Dirac unique

  • BuildOS unifies CAD, PLM, MBOM, BOP, and operator instructions into one living model.
  • Dirac ships GovCloud-ready deployments and Marketplace procurement for regulated aerospace and defense buyers.
  • Operator+ and automatic assembly ordering convert engineering knowledge into station-ready execution faster.

Dirac and AWS launch BuildOS to cut production ramp-up times in half with AI-driven process design

Dirac and Amazon Web Services are partnering to bring AI-driven process design to advanced manufacturers, particularly in defense and aerospace sectors. The collaboration delivers Dirac's BuildOS platform on AWS infrastructure, including AWS GovCloud for handling controlled data. The platform addresses a critical bottleneck in modern manufacturing: whilst engineering teams iterate quickly, design changes trigger hours of manual rework reconciling CAD models and updating production instructions. Bain reports aerospace and defense programme cost overruns have surged to nearly $46bn, with delivery timelines stretching from 8 to 11 years. BuildOS replaces document-driven production with an automated, model-based system. Customer Anduril has already compressed work instruction authoring by nearly 90%. However, adoption challenges remain: whilst 89% of manufacturers plan to implement AI in production, only 16% have achieved their AI-related targets, according to BCG.

Dirac brings AI process planning platform to Microsoft Azure, cutting work instruction time by 95%

Dirac has achieved co-sell ready status with Microsoft, bringing its AI-driven manufacturing platform BuildOS to enterprise manufacturers via Azure. The platform targets aerospace, defence, industrial equipment, and machinery sectors. BuildOS serves as an AI-native process planning system that works directly from CAD and PLM data. It generates process plans, work instructions, and manages engineering changes that traditionally required multiple enterprise applications and manual documentation. Customers report significant efficiency gains: up to 95% reduction in work instruction creation time, 85% faster engineering change cycles, 85% faster first-pass builds, and 95% faster operator onboarding. The platform runs on Microsoft Azure infrastructure, utilising GPU-enabled virtual machines for CAD processing and Azure database services. It is now available in Microsoft Marketplace, allowing manufacturers to deploy it against existing Azure commitments.
