Module Pricing
Different modules have different tool costs based on complexity and resource requirements.Mathcad Module
Included in Base Model
Generate, edit, validate, and QC Mathcad Prime 9+ calculation sheets
Tool Cost Structure
- ✅ Up to 10 tool calls per request: No additional charge
- Every 5 additional tool calls: +1 request
Common Tool Usage
- Simple Calculation
- Complex Calculation
- QC Mode
Tool Usage: 5-8 toolsCost: No extra charge (within 10 free tools)Example:
- Generate a basic beam design calculation
- Simple anchor design per ACI 318-19
- Load calculation with code lookup
Most calculations complete within 10 tool calls, meaning no additional request charges beyond your initial prompt.
RISA 3D Module
Private Beta
Read, analyze, and extract data from RISA-3D models
Activation
Request access at bhosh@stru.ai (no additional charge during beta)Tool Cost Structure
- ✅ Reading RISA files: No charge
- Editing/Interaction: 0.25 requests per tool
Example Workflow
1
Open Model
“Open Lateral_System.r3d and extract column forces”Cost: 1 request (read-only operation)
2
Extract Data
“Extract forces for 12 columns from the ‘1.2D + E’ load combination”Cost: 1 request + (1 tool × 0.25) = 1.25 requests
3
Generate Calculations
“Generate Mathcad calculations from extracted forces”Cost: 1 request (Mathcad tool costs apply)

Frequently Asked Questions
When will RISA 3D and SAP2000 be generally available?
When will RISA 3D and SAP2000 be generally available?
Both modules are currently in private beta. General availability is planned for Q2 2025.To join the beta:
- Email bhosh@stru.ai with “RISA Beta” or “SAP2000 Beta”
- Describe your typical workflow
- We’ll contact you about beta access
Will modules cost extra after beta?
Will modules cost extra after beta?
During beta, both RISA 3D and SAP2000 modules are available at no additional charge.After general release:
- RISA 3D: Included in Pro and Enterprise plans
- SAP2000: Included in Pro and Enterprise plans
- Custom Tool Integration: Premium service, quoted separately
Do I need the software installed?
Do I need the software installed?
RISA 3D: No, the Agent can read .r3d files directly. You don’t need RISA installed.SAP2000: Yes, SAP2000 must be running on your machine. The Agent connects via the SAP2000 API.Custom Tools: Depends on the tool. We can host cloud-based tools, or they run on your machine.
Can the Agent modify my models?
Can the Agent modify my models?
RISA 3D (Beta): Currently read-only. The Agent extracts data but doesn’t modify .r3d files.SAP2000 (Beta): Yes, the Agent can modify open models, re-run analysis, and extract results. Save your work before Agent operations.Future: Exploring “what-if” scenarios where Agent creates temporary copies for parametric studies.
What other software integrations are planned?
What other software integrations are planned?
We’re actively developing integrations for:
- ETABS (similar to SAP2000) - Q2 2025
- SAFE (foundation design) - Q3 2025
- RAM Structural System - Q3 2025
- Revit (read geometry, extract loads) - Q4 2025
How much do Mathcad tool calls typically cost?
How much do Mathcad tool calls typically cost?
Most calculations use 5-10 tools, which means no additional charge beyond your initial request.Only complex calculations with 15+ tool calls incur extra costs, typically 1-2 additional requests.During Beta: Unlimited tool calls are waived for testing.
