Grid Plane Surface



A Grid Plane Surface is used by Grid Loads.

A grid plane defines the geometry of a surface, and the load behaviour of the grid plane is defined by a grid surface.

In Grasshopper, a Grid Plane Surface contains both the information of what in GSA is known as a Grid Plane and a Grid Surface

The Grasshopper plugin will automatically create a fitting Grid Plane Surface when using the Create Grid Point Load, Create Grid Line Load or Create Grid Area Load components.

Grid Plane Surfaces can also be created independently using the Create Grid Plane and Create Grid Surface components.
