Custom AutoCAD & Autodesk Plugins: Automate 3D Modifications with AI

Architects, mechanical engineers, and civil engineers spend 30-50 percent of their time on repetitive modifications inside AutoCAD, Revit, Fusion 360, and Inventor. TechNexusGen builds bespoke plugins that automate these workflows—often integrated with AI to generate parametric variants, run clash detection, or auto-dimension drawings.

Plugin Technologies We Use

• AutoCAD .NET API (C#) and ObjectARX (C++)
• Revit API for BIM automation
• Fusion 360 Add-Ins (Python and JavaScript)
• Inventor iLogic and API
• Autodesk Forge / Platform Services for cloud integrations

Example AI-Powered Plugins We Have Built

A precast concrete manufacturer asked us to auto-generate hundreds of beam variants from a single template—our plugin uses parametric rules plus an LLM to interpret natural-language design briefs. A mechanical OEM uses our Fusion 360 plugin to scan imported STEP files, identify weldments, and auto-place bill-of-materials annotations.

How AI Enhances CAD Workflows

Modern AI lets us go beyond rule-based macros. Vision models can identify drawing components from raster PDFs and auto-rebuild them in 3D. LLMs can read engineering specifications and produce parametric inputs. Generative design algorithms create thousands of viable geometries within engineering constraints.
