+Default schema is `IFC4`.

+### Drawing and rendering tools
+
+#### ifc_plot
+
+Generate a 2D technical drawing of the loaded model and return it as an inline image.
+
+```
+ifc_plot()
+ifc_plot(selector="IfcWall", view="floorplan", scale=0.01, output_path="/tmp/plan.svg")
+ifc_plot(element_ids=[10, 11], view="floorplan")
+```
+
+Parameters:
+
+- `selector` -- ifcopenshell selector to restrict plotted elements
+- `element_ids` -- step IDs of elements to highlight; others are faded
+- `view` -- `"floorplan"` (default), `"elevation"`, `"section"`, or `"auto"`
+- `width_mm`, `height_mm` -- paper size in mm (default: 297 x 420)
+- `scale` -- model-to-paper ratio (default: 0.01 = 1:100)
+- `png_width`, `png_height` -- raster output size in pixels (default: 1024 x 1024)
+- `output_path` -- optional path to also save to disk (`.svg` for vector, otherwise PNG)
+
+Returns an inline PNG the LLM can inspect. Requires `ifcopenshell.draw`.
+
+#### ifc_render
+
+Render the loaded model to a 3D PNG image.
+
+```
+ifc_render()
+ifc_render(selector="IfcWall", view="iso", output_path="/tmp/model.png")
+ifc_render(element_ids=[10, 11], view="south")
+```
+
+Parameters:
+
+- `selector` -- ifcopenshell selector to restrict rendered elements
+- `element_ids` -- step IDs of elements to highlight; others are shown translucent
+- `view` -- `"iso"` (default), `"top"`, `"south"`, `"north"`, `"east"`, or `"west"`
+- `output_path` -- optional path to save the PNG to disk
+
+Returns an inline PNG. Requires `pyvista` and the IfcOpenShell C++ geometry bindings.
+
+### Shape builder tools
+
+#### ifc_shape_list
+
+List all available `ShapeBuilder` methods with brief descriptions.
+
+```
+ifc_shape_list()
+```
+
+#### ifc_shape_docs
+
+Show full documentation for a specific `ShapeBuilder` method.
+
+```
+ifc_shape_docs(method="extrude")
+ifc_shape_docs(method="create_ellipse")
+```
+
+#### ifc_shape
+
+Execute a `ShapeBuilder` method on the loaded model.
+
+```
+ifc_shape(method="extrude", params='{"profile": "42", "magnitude": 3.0}')
+```
+
+`params` is a JSON string; entity references are resolved by step ID (same coercion as `ifc_edit`).
