What Is CAD Automation?

CAD Automation is the use of programming, APIs, scripts, and software tools to automate repetitive or complex tasks inside CAD applications.

Instead of performing the same operation manually hundreds of times, engineers can develop an automated workflow that performs the task consistently.

For example, a CAD Automation application could:

• Create standard components automatically

• Generate engineering drawings

• Update design parameters

• Create assembly structures

• Generate BOMs

• Extract model information

• Rename and organise CAD files

• Export models into different formats

• Process hundreds of CAD files

• Validate engineering data

• Connect CAD with Excel, databases, PLM, or ERP systems

The objective is simple:
