Function exportAssemblySTEP

exportAssemblySTEP(
shapes?: ShapeOptions[],
options?: { modelUnit?: SupportedUnit; unit?: SupportedUnit },
): Result<Blob>
Create an XCAF document from shape configs and export as a STEP blob.

Builds an in-memory XCAF assembly with named, colored shape nodes, writes it through STEPCAFControl_Writer, and returns the file contents as a Blob. The XCAF document is deleted after export to avoid memory leaks.
Parameters
- shapes: ShapeOptions[] = []
  Shapes to include in the STEP file.
- options: { modelUnit?: SupportedUnit; unit?: SupportedUnit } = {}
  Optional unit settings for the STEP writer.
  - OptionalmodelUnit?: SupportedUnit
    Model unit; defaults to the write unit.
  - Optionalunit?: SupportedUnit
    Write unit (e.g. 'MM', 'INCH').
Returns Result<Blob>
Result containing a Blob with MIME type application/STEP.
Example
```
const result = exportAssemblySTEP(
  [{ shape: myBox, color: '#00ff00', name: 'box' }],
  { unit: 'MM' }
);
if (result.ok) saveAs(result.value, 'model.step');
```
