gdsfactory.geometry.trim#

gdsfactory.geometry.trim(component: Component, domain: list[tuple[float, float]], precision: float = 0.0001, return_ports: bool | None = False) → Component[source]#

Trim a component by another geometry, preserving the component’s layers and ports.

Useful to get a smaller component from a larger one for simulation.

Parameters:

  • component – Component(/Reference).

  • domain – list of array-like[N][2] representing the boundary of the component to keep.

  • precision – float Desired precision for rounding vertex coordinates.

  • return_ports – whether to return the included ports or not. Ports are always renamed to avoid inheritance conflicts.

Returns: New component with layers (and possibly ports) of the component restricted to the domain.

import gdsfactory as gf
c = gf.components.straight_pin(length=10, taper=None)
trimmed_c = gf.geometry.trim(component=c, domain=[[0, -5], [0, 5], [5, 5], [5, -5]])
trimmed_c.plot_matplotlib()
