Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
3 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by Cai-aa on GitHub. Read the source before you install it.

Installation

Install the Abaqus Geometry AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/Cai-aa/CAE-Agent-Hub/tree/main/Skill/abaqus/modeling/abaqus-geometry
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/Cai-aa/CAE-Agent-Hub.git /tmp/CAE-Agent-Hub
mkdir -p .claude/skills
cp -r /tmp/CAE-Agent-Hub/Skill/abaqus/modeling/abaqus-geometry .claude/skills/abaqus-geometry

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Abaqus Geometry in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Abaqus Geometry on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Abaqus Geometry is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Abaqus Geometry Skill

Create parts, assemblies, and import CAD files for finite element analysis.

When to Use This Skill

Route here when user mentions:

"create a box/beam/plate/bracket"
"draw geometry", "make a cylinder/tube"
"import STEP/IGES file"
"extrude", "revolve", "create assembly"
"position the parts", "build a component"

Route elsewhere:

Meshing the geometry -> /abaqus-mesh
Defining materials/sections -> /abaqus-material
Applying loads or BCs -> /abaqus-load, /abaqus-bc
Full analysis workflow -> /abaqus-static-analysis

Key Decisions

1. How to Create Geometry?

Shape	Approach
Box, plate, beam	Sketch rectangle + extrude
Cylinder, tube	Sketch circle + extrude
Pipe, disc, shaft	Sketch profile + revolve
Complex/existing	Import STEP/IGES
Quick prototype	Primitives

Decision guidance:

Simple prismatic shape? -> Sketch + extrude
Axisymmetric part? -> Sketch + revolve
Existing CAD model? -> Import STEP file

2. Where to Place Origin?

Origin Location	When to Use
Corner (0,0,0)	Asymmetric parts, easier coordinate math
Center (0,0,0)	Symmetric parts, rotation about center

3. Part vs Instance Coordinates

Context	Use
Geometry creation, section assignment	Part coordinates
BCs, loads, sets, finding faces	Instance/assembly coordinates

Important: After creating an instance, use instance.faces.findAt() not part.faces.findAt().

What to Ask User

If unclear, ask:

Shape type? Box, cylinder, imported CAD?
Dimensions? Length, width, height in mm
Origin location? Corner or center?
Import file available? Path to STEP/IGES?
Features needed? Holes, fillets, chamfers?

Workflow

Step 1: Create Model and Part

Create the model container, then a 3D deformable part.

Step 2: Define Geometry

Choose approach based on shape:

Sketch + Extrude: Draw 2D profile, extrude to 3D
Sketch + Revolve: Draw profile, revolve around axis (360 degrees for full solid)
CAD Import: Open STEP/IGES, create part from geometry file

Step 3: Add Features (Optional)

Add secondary features if needed:

Cut holes using cut extrude
Round edges with fillet
Partition cells for BC/load regions

Step 4: Create Assembly Instance

Create root assembly with Cartesian datum, then create instance from part.

Step 5: Create Sets and Surfaces

Create named sets/surfaces on instance (not part) for:

BC regions
Load application surfaces
Design regions (for optimization)

Finding Entities

Two methods to locate faces/edges:

findAt() - Exact coordinates (point must be ON the entity)
getByBoundingBox() - Tolerant box search (better for automation)

Combine multiple entities with + operator.

Common Pitfalls

Problem	Cause	Solution
"Sketch is not closed"	Gap in sketch entities	Ensure lines connect to form closed loop
"Cannot find face at coordinates"	Point not exactly on face	Use bounding box or verify coordinates
"Part has no cells"	Sketch not extruded	Call BaseSolidExtrude or similar
"Instance already exists"	Duplicate name	Use unique name or delete existing

Validation Checklist

Before proceeding to mesh/analysis:

Part created with correct dimensions
Geometry is watertight (no gaps)
Instance created in assembly
Sets created on instance for BC/load regions
Partitions added if needed for region selection

Units

All dimensions use consistent units (mm-tonne-s-N-MPa):

Length: mm
Coordinates: mm

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Abaqus Geometry AI skill do?

Create and manipulate Abaqus geometry - parts, sketches, extrusions, CAD import. Use for any geometry creation task including box, cylinder, or STEP/IGES import.

Why use Abaqus Geometry on TypingMind?

Because you install it once and use it with any model. Abaqus Geometry is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Abaqus Geometry in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/Cai-aa/CAE-Agent-Hub/tree/main/Skill/abaqus/modeling/abaqus-geometry. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Abaqus Geometry?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Abaqus Geometry?

As many as you like. As long as a model supports skills, you can use Abaqus Geometry with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Abaqus Geometry AI skill free?

Yes. It is published on GitHub by Cai-aa under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
