 Constrain a point to be fixed to a position.
 
 ```kcl
-solver::fixed
+solver::fixed(@points: [Segment | Point2d; 2+])
 ```
 
 `fixed()` is an alias for `coincident()`. By convention, `fixed()` is used when one of the points is a known location, not solved with constraints and not another point in the sketch.
 
+Calling `fixed()` with one segment, such as `fixed(edge)`, is invalid and produces an argument error. `fixed()` requires an array of at least two points or segments. To anchor a point to a fixed position, pass both values, for example `fixed([edge.start, ORIGIN])`.
+
+
 See [coincident()](/docs/kcl-std/functions/std-solver-coincident) for more info.
 
+### Arguments
+
+| Name | Type | Description | Required |
+|----------|------|-------------|----------|
+| `points` | [[`Segment`](/docs/kcl-std/types/std-types-Segment) or [`Point2d`](/docs/kcl-std/types/std-types-Point2d); 2+] | Two or more sketch entities that should be coincident. When more than two inputs are provided, each item must be a point or `ORIGIN`. | Yes |
+
+
+### Examples
+
+```kcl
+profile = sketch(on = XY) {
+  edge = line(start = [var 0mm, var 0mm], end = [var 10mm, var 0mm])
+  fixed([edge.start, ORIGIN])
+  horizontal(edge)
+  horizontalDistance([edge.start, edge.end]) == 10mm
+}
