GET THE FIRST CURVE FROM THE COLLECTION OF CURVES¶
Extracts the first curve from a multi-curve collection. Use this worker when a downstream step requires a single curve and you want to select the leading entry from an ordered curve group.
When to use¶
Classification: process.
Tagged: collection, curve_group, curves, first_curve, selection, transform.
Inputs¶
| Label | ID | Type | Default | Required | Description |
|---|---|---|---|---|---|
| Curve Group | curvegroup | vector | — | Ordered collection of curves (vector/multi-curve group) from which the first curve will be extracted; must contain at least one curve — leave unconnected only if the curve group is empty and no output is needed. |
Outputs¶
| Label | ID | Type | Description |
|---|---|---|---|
| curves_firstcurve_output_1 | curves_firstcurve_output_1 | vector | The first curve extracted from the input curve group, returned as a single vector curve ready for downstream processing. |
