AI tools · Plugin for CSI software
Axiom

Build, edit, and query CSI models using AI directly inside ETABS, SAP2000, and SAFE.
Axiom brings conversational agents and targeted tools into your workflow, so models can be created, modified, and understood without leaving your software.

Overview
Two types of AI capability.

Axiom brings AI into your CSI software in two distinct ways. MCP Agents are conversational systems that act on your model. AI Plugins are focused tools that perform a specific task.

MCP Agents — conversational
Claude reads your brief,
builds your model,
extracts your results.

Describe your structure or upload a design brief — the agent builds the model, defines loading, runs analysis, and lets you query and modify it through conversation. The model remains active in your software as you work

AI Plugins — task-focused
Targeted AI tools
for specific workflows.

Seven plugins each handle one engineering workflow: generate a model from a natural language prompt, edit an existing model with text commands, convert a PDF structural drawing to an ETABS model, or ask questions about your model in plain language. Each plugin installs separately inside the relevant CSI software and runs as a panel alongside your existing workflow.

Axiom requires an AI API key from Anthropic (Claude) or OpenAI (GPT-4). Your key is entered once in the Axiom settings panel and used for all AI requests. You connect your own AI account, giving you direct control over usage, cost, and data. Axiom does not store or access your API key or AI data.
MCP Agents
Build and query models
through conversation.

Two agents currently available. Both work with ETABS and SAFE. Each requires the Axiom MCP Agent plugin installed in your software and a valid API key.

Agent 01
Model Builder

Feed Claude a design brief, a set of design criteria, or a plain description of your structure. The agent reads the document, creates the full ETABS or SAFE model — geometry, section assignments, material properties, load cases, load combinations — and keeps the model open for further conversation.

Reads design briefs and criteria documents (PDF, text)
Creates geometry, sections, materials, supports
Defines load cases and combinations per code
Runs analysis on request
Continues conversation — modify, refine, redefine
ETABS
Team
Agent 02
Result Extractor and Viewer

Connect Claude to an analyzed ETABS or SAFE model. Ask questions about results in plain language — identify critical members, extract forces and moments, generate plots, compare load cases, and export findings. Works with models built by the Model Builder agent or any existing analyzed model.

Query analysis results in natural language
Identify members by demand/capacity ratio, stress, or deflection
Generate plots — envelopes, diagrams, comparisons
Compare results across load cases and combinations
Export results to tables or structured reports
ETABS
Team
Using both agents together: Start a session with the Model Builder to create and analyze a structure. Then switch to the Result Extractor in the same conversation to query and visualize the results. The model context carries through — you do not need to reload or re-describe the structure.
AI Plugins
Focused AI tools.

Each plugin is built for a specific workflow within CSI software - focused, purpose-driven tools that do one thing well.

Model Generation
2 plugins
Prompt-Based Model Generation
ETABSSAP2000Bridge ExpressSAFE

Describe a structural system in plain language, and the plugin creates the model with geometry, materials, sections, and basic loading.

Pro
Prompt-Based Editing
ETABSSAP2000Bridge Express

Change section properties, add or remove elements, adjust loads, update boundary conditions — described in a prompt.

Pro
Design Assistants
2 plugins
Interactive Prompt-Based Design
Bridge Express

Iterative, conversational design workflow. Describe design intent, review suggestions, refine interactively.

Pro
AI-Based Beam Design
ETABS

Use machine learning to predict beam design outcomes and suggest section configurations based on loading and span parameters.

Pro
Converters
1 plugin
PDF Drawings to ETABS Model
ETABS

Upload a structural drawing PDF. The plugin reads grid lines, column positions, beam spans, and floor levels using AI recognition and creates the corresponding ETABS model elements. Results should be reviewed carefully before use.

Pro
Installation
One installer per plugin per software.

Each plugin installs independently within its CSI software, creating a modular setup that keeps your tools streamlined, focused, and aligned with your workflow.

1
Get your AI API key
Axiom requires an API key from Anthropic (Claude) or OpenAI. Create an account on the provider's website, generate an API key, and keep it ready for step 4.
2
Download the plugin
From the sections above, download the installer for each plugin you need. Each is a separate file — one per plugin per software.
AxiomPlugin_ModelExplorer_ETABS_v1.exe
3
Run the installer
Close your CSI software. Run the installer — it detects your software installation and places the plugin in the correct location.
4
Open your CSI software and enter your key
Restart your CSI software. The Axiom panel appears in the toolbar. Click Settings and paste your API key. This is a one-time setup.
Axiom → Settings → API Key
5
Open a model and start
With a model open, click the Axiom panel. For plugins — type a prompt and run. For MCP Agents — start a conversation, describe your structure or upload a brief.
6
For MCP Agents — use Claude desktop
MCP Agents run through the Claude desktop application. Install Claude for desktop, connect the Axiom MCP server, then open ETABS or SAFE and start your session from within Claude.
Claude → Add MCP Server → Axiom
System requirementsSystem requirements: Windows 10 or 11  ·  ETABS v21+, SAP2000 v24+, Bridge Express v1.0+, or SAFE v22+ must be installed  ·  Active internet connection for AI requests  ·  Claude for Desktop required for MCP Agents
