Why Custom CAD Software Development Matters

Off-the-shelf CAD tools are powerful – but often too generic for complex, real-world projects.

Engineering teams face daily challenges:

  • Wasted hours on repetitive tasks like routing, tagging, or annotation
  • Disconnected workflows between CAD, ERP, simulation, and procurement
  • Manual input of spec data into tools like CAESAR II or HYSYS
  • Limitations of rigid plugins that don’t match internal standards
  • Difficulty scaling or adapting tools to project-specific needs

Custom CAD software bridges these gaps – automating design logic, integrating systems, and aligning tools with your workflows.

At InStandart, we build exactly what your engineers need – not what off-the-shelf platforms assume.

Our Expertise

CAD Plugins & Extensions

AutoCAD / Plant 3D / MEP – automate drawing generation, routing, annotation, spec-based component placement
Revit – develop project-specific add-ins for BIM data management, export, clash tagging, parameter validation
AVEVA E3D & Diagrams – PML-based modules for attribute handling, spec compliance, and model customization
Intergraph Smart 3D – model automation, reporting, and integration extensions (on request)

BIM Automation & Toolsets

Custom Revit tools for MEP layout, family insertion, and space zoning

Success Stories

Integration of CAD/BIM with SAP for a Midstream Gas Processing Plant

A gas processing plant had constant mismatches between their AVEVA E3D models and SAP. Engineers transferred data by hand, which caused frequent BOM errors and delayed procurement. The wrong materials showed up on site — and the right ones arrived late.

We built a sync tool that connects E3D directly to SAP. It auto-tags assets, validates specs against master data, and keeps both systems current throughout the project.

Result: 85% better data sync. 70% fewer data-related reworks. 60% faster procurement readiness.

Operator Training Simulator for an Air Separation Unit Built from Detailed Design

Traditional training took 4-6 months with safety incidents during hands-on practice. Emergency scenarios couldn’t be practiced on live equipment – too dangerous. New operators felt unprepared when emergencies actually occurred.

We built a Unity-based 3D training simulator from their P&IDs and process models. Operators practice normal operations, startup/shutdown procedures, and emergency responses in a safe virtual environment – making mistakes and learning without real-world consequences.

Result: Training time cut 50% (4-6 months → 2-3 months). Safety incidents reduced 80%. Emergency response readiness improved 70%.
