GeoStudio API (Python)

Hi everyone,

I’m automating SLOPE/W runs via the GeoStudio Python API and I need to access the reinforcements so I can read and modify, line-by-line, the Tensile Capacity and Pullout Resistance.I’m struggling to find the correct object tree/collection for reinforcements in the API.

What I want to do

• Iterate over the reinforcements defined in the model (either Line or Face mode),
• Read/modify TensileCapacity and PulloutResistance for each element,
• Solve the analysis and store the critical FoS, looping for combinations (sensitivity/reliability workflows).

Environment

• GeoStudio: 2025.1 (SLOPE/W)
• Python API: gsi-2025.1.0 (official wheel)
• OS: Windows 11 • Python 3.12 • grpcio up to date
• Project: .gsz file with reinforcements already defined in the GUI

What I’ve tried / what I can see

• I can open the project, select the analysis, and list CurrentAnalysis.GeometryItems (e.g., Regions, Boundaries, etc.).
• But I cannot find where the reinforcements live.
• === Scanning likely collections ===CurrentAnalysis.GeometryItems.Regions: 9 items=== Trying direct collections ===(no obvious 'Reinforcement', 'Nail', or 'Tieback' collection shows up)
• I also looked under Project.Library (materials/structures) but didn’t locate reinforcements there either.

Concrete questions

1. What is the correct path/collection in the API to access SLOPE/W reinforcements? (Something like analysis.Reinforcements, analysis.StructuralElements, Project.Library.ReinforcementTypes, …?)
2. How can I iterate by “line” (Line mode) or by face (Face mode) and, for each item, read/write TensileCapacity and PulloutResistance?
3. Are there API differences between Face-defined vs Line-defined reinforcement that I should handle (e.g., property inheritance by material/layer)?
4. Is there any official example (or code excerpt) that demonstrates reading/writing these two parameters specifically?
5. If reinforcements aren’t under GeometryItems, do they live under a Structural/Support elements node or in Libraries/Templates referenced by the analysis?

I can attach a minimal .gsz with 2–3 reinforcements if that helps.

Thanks!
