CAD Customization & Automation Services
Extending CAD to Do Exactly What You Want It to Do
Custom plugins, automations, and toolchain workflows built around your engineering reality. We make multi-tool workflows easier, extend your CAD capabilities, and automate tedious manual steps.
What We Specialize In
Multi-Tool Workflow Gaps
We connect data from CAD to analysis and downstream manufacturing tools, so the workflow stays consistent and faster to execute.
Missing or Domain-Specific Functionality
We build the plugins and automation tools that your engineers wish existed inside their CAD tools, tailored to your products and processes.
CAD-to-PLM Pipelines
We build export, translation, and validation tools that make your CAD workflows enterprise-ready.
Automate Repetitive Workflows
Streamline CAD workflows by automating routine tasks like feature generation, model cleanup, and drawing creation, so engineers can focus on high-value design.
CAD Kernel API Integration
Build high-performance tools with kernel-level access for B-Rep extraction, geometry repair, custom features, and simulation prep using Parasolid, ACIS, CGM, and CAD APIs.
CAD Tools & SDKs We Customize
We work with a wide range of CAD platforms and SDKs to create plugins, automations, and interoperability workflows tailored to your tools and teams.
