What it does
Abaqus Geometry is an agent skill from Cai-aa/CAE-Agent-Hub. Create and manipulate Abaqus geometry - parts, sketches, extrusions, CAD import. Use for any geometry creation task including box, cylinder, or STEP/IGES import.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `UPSTREAM.md` and `metadata.json`).
The licence is MIT.
When your agent uses it
- Any geometry creation task including box
- STEP/IGES import
Example prompts
- “/abaqus-geometry”
Requirements
- Pre-approved tools (allowed-tools): Read, Write, Edit, Glob, Grep, Bash(abaqus:*)
Workflow steps
8 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 194ef49. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditGlobGrepBash(abaqus:*)
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Abaqus Geometry loads about 1.1k tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 467 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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
Show full SKILL.md (188 more words)Show less
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
