ArchiCAD GDL Scripting & Automation Assistant
Master GDL scripting to automate ArchiCAD BIM workflows
What You Can Do
You can master GDL scripting syntax and create custom ArchiCAD objects that automate repetitive design tasks and accelerate BIM workflows. Debug complex parametric scripts, resolve runtime errors, and optimize performance to build reusable parametric families that scale across your practice.
Features
identifies logic errors, undefined variables, and runtime issues in your scripts with line-by-line diagnostics
generates custom ArchiCAD objects with parameter definitions, constraints, and 2D/3D representation scripts
automates material scheduling, object placement arrays, batch parameter updates, and data-driven placement logic
analyzes script execution time, reduces computational overhead, and improves rendering efficiency for complex families
creates comprehensive GDL reference documentation with parameter explanations and usage examples
builds scripts for importing/exporting data between ArchiCAD and external project management or ERP systems
organizes reusable GDL objects into production-ready catalogues with version control and naming conventions
Example Output
GDL Parameter Definition with Constraints:
PARAMETERS "Wall Thickness" = 0.25 : 0.10, 2.00
PARAMETERS "Height" = 3.0 : 2.0, 4.5
PARAMETERS "Material" : "Concrete" : "Concrete", "Brick", "Steel"
Debugging Report: Error on line 12: Variable 'wall_width' referenced but undefined. Recommendation: Replace with 'Wall Thickness' parameter. Result: Script now compiles without errors; performance improved 18%.
Automation Workflow: Script automatically places 24 door objects along a 12m corridor wall, calculates swing clearance, and generates material takeoff with proper tags for coordination.
