+# Dimension Tools (5)
+
+All dimension tools return entity info with handle. Dimensions are placed on the current layer unless `layer` is specified.
+
+---
+
+## dimension_linear
+Linear dimension between two points (horizontal or vertical measurement).
+
+| Param | Type | Description |
+|-------|------|-------------|
+| `x1, y1` | `float` | First extension line origin |
+| `x2, y2` | `float` | Second extension line origin |
+| `dim_x, dim_y` | `float` | Dimension line position (controls placement) |
+| `layer` | `str \| null` | Target layer |
+
+## dimension_aligned
+Aligned dimension — measures true distance between points regardless of angle.
+
+| Param | Type | Description |
+|-------|------|-------------|
+| `x1, y1` | `float` | First point |
+| `x2, y2` | `float` | Second point |
+| `distance` | `float` | Offset distance for dimension line |
+| `layer` | `str \| null` | Target layer |
+
+## dimension_angular
+Angular dimension between two lines meeting at a vertex.
+
+| Param | Type | Description |
+|-------|------|-------------|
+| `vertex_x, vertex_y` | `float` | Angle vertex point |
+| `start_x, start_y` | `float` | First line endpoint |
+| `end_x, end_y` | `float` | Second line endpoint |
+| `dim_x, dim_y` | `float` | Dimension arc position |
+| `layer` | `str \| null` | Target layer |
+
+## dimension_radius
+Radius dimension for circles and arcs.
+
+| Param | Type | Description |
+|-------|------|-------------|
+| `center_x, center_y` | `float` | Circle/arc center |
+| `radius` | `float` | Radius value |
+| `angle` | `float` | Leader angle in degrees (where arrow points) |
+| `layer` | `str \| null` | Target layer |
+
+## dimension_diameter
+Diameter dimension across a circle.
+
+| Param | Type | Description |
+|-------|------|-------------|
+| `x1, y1` | `float` | First point on diameter |
+| `x2, y2` | `float` | Opposite point on diameter |
+| `layer` | `str \| null` | Target layer |
