🎯Point

A point load is a concentrated force (and optionally a moment) applied at a single point of the structure. In Alpaca4d this is typically used to represent loads from columns, machines, connections, or other localized actions.

The Grasshopper component is Point Load (Alpaca4d) and creates an Alpaca4d.Loads.PointLoad object.

Inputs

• Point: Rhino Point where the load acts in space. This point will be associated with the nearest structural node during assembly.

• Force: Rhino Vector with the load components ([Fx, Fy, Fz]) in global coordinates, in units of ([Force]).

• Moment (optional): Rhino Vector with the moment components ([Mx, My, Mz]) in global coordinates, in units of ([Force·Length]). If omitted, only the force is applied.

Output

• Load: A generic Load object that can be connected to a load pattern component and then to the Assemble component.

Usage notes

• Use point loads when the area of application is small compared to the structural dimensions (e.g. a column reaction on a beam).

• The force and moment direction are always defined in the global axes, regardless of member orientation.

• Multiple point loads can be combined in the same load pattern to form a load case.
