class keysight.ads.de.tech.DerivedLayer

Represents a derived layer.

A derived layer is a (virtual) layer that is formed by operations on shapes from one or more other layers. Derived layers typically don’t have any shapes.

The derived layer contains all the shapes that result by performing the sizing operation on all the shapes from the source layer. The sizing operation uses the distance parameter to change the size of each shape from the source layer.
