The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.
boolean_models Combine CAD models ~55
Create a new model by union, difference, or intersection of two or more saved models.
| Name | Type | Req | Description |
|---|---|---|---|
| color | string | – | – |
| modelIds | array | yes | – |
| name | string | yes | – |
| operation | string | yes | – |
No output schema declared.
No examples provided.
create_model Create CAD model ~75
Create a separate new CAD model from a declarative parametric shape tree. Do not use this to modify an existing model; load it and call update_model instead. Supports primitives, extrusions, transforms, mesh input, and boolean operations.
| Name | Type | Req | Description |
|---|---|---|---|
| color | string | – | – |
| name | string | yes | – |
| shape | – | yes | – |
No output schema declared.
No examples provided.
delete_model Delete CAD model ~88
Permanently delete one saved CAD model. Call list_models or load_model first to identify the exact modelId, and pass expectedRevision when available to avoid deleting a newer edit.
| Name | Type | Req | Description |
|---|---|---|---|
| expectedRevision | integer | – | Current revision from load_model; rejects stale edits instead of overwriting them |
| modelId | string | yes | Saved model ID from list_models, load_model, or a prior tool result |
No output schema declared.
No examples provided.
duplicate_model Duplicate CAD model ~33
Create an editable copy of a saved CAD model.
| Name | Type | Req | Description |
|---|---|---|---|
| modelId | string | yes | – |
| name | string | – | – |
No output schema declared.
No examples provided.
export_model Export CAD model ~35
Export a saved CAD model as ASCII STL or OBJ data.
| Name | Type | Req | Description |
|---|---|---|---|
| format | string | yes | – |
| modelId | string | yes | – |
No output schema declared.
No examples provided.
generate_model Generate CAD model ~159
Generate a built-in parametric template: bracket, pipe, gear, enclosure, or bolt. To revise a previously generated model, pass its modelId and expectedRevision to regenerate it in place. Omit modelId only when the user wants a separate new model.
| Name | Type | Req | Description |
|---|---|---|---|
| color | string | – | Color for a new model, or optional replacement color when regenerating |
| expectedRevision | integer | – | Current revision from load_model; rejects stale edits instead of overwriting them |
| modelId | string | – | Existing model to regenerate in place; omit only to create a new model |
| name | string | – | Name for a new model, or optional replacement name when regenerating |
| parameters | object | – | – |
| template | string | yes | – |

No examples provided.
load_model Load CAD model ~64
Load a saved CAD model, including the modelId, current revision, complete editable parametric definition, and render mesh. Call this before update_model or delete_model.

| Name | Type | Req | Description |
|---|---|---|---|
| modelId | string | – | Model to select initially |
No output schema declared.
No examples provided.
transform_model Transform CAD model ~91
Apply an incremental translation, Euler rotation in degrees, or scale to a CAD model.
| Name | Type | Req | Description |
|---|---|---|---|
| expectedRevision | integer | – | Current revision from load_model; rejects stale edits instead of overwriting them |
| modelId | string | yes | Saved model ID from list_models, load_model, or a prior tool result |
| rotation | array | – | – |
| scale | array | – | – |
| translation | array | – | – |
No output schema declared.
No examples provided.
update_model Update CAD model ~189
Modify an existing saved model in place while preserving its modelId. Use patches for small edits (example: replace /shape/size/0), or shape to replace the complete definition. Load the model first and pass its expectedRevision. Never call create_model merely to revise an existing model.
| Name | Type | Req | Description |
|---|---|---|---|
| color | string | – | Optional replacement six-digit hex color |
| expectedRevision | integer | – | Current revision from load_model; rejects stale edits instead of overwriting them |
| modelId | string | yes | Saved model ID from list_models, load_model, or a prior tool result |
| name | string | – | Optional replacement name |
| patches | array | – | Targeted edits applied in order to the current model. Use add for a new field/array item, replace for an existing value, and remove for an optional field. |
| shape | – | – | Optional complete replacement shape; cannot be combined with patches |
No output schema declared.
No examples provided.
validate_shape Validate CAD shape ~56
Preflight a complete parametric shape without saving it. Reports static polygon/mesh topology errors and warnings, then asks the CAD kernel to verify the solid. Use this before create_model or update_model for complex shapes.
| Name | Type | Req | Description |
|---|---|---|---|
| shape | – | yes | – |
No output schema declared.
