compas_cem.supports ¤

Supports that anchor the nodes where the trails of a topology diagram end.

Classes¤

NodeSupport ¤

NodeSupport(node, **kwargs)

A support that anchors one node of a diagram.

Parameters:

  • node –

    The key of the node to support.

Notes

Supports are where the trails of a topology diagram end. The form-finding algorithm walks back from every support to an origin node to build them.

Methods:¤

from_point classmethod ¤
from_point(point)

Create a support from a point.

Parameters:

  • point –

    The coordinates of the position to support.

Returns:

  • support –

    A support with no node key, positioned at the given point.

Notes

The support binds to a diagram node whose coordinates match the point. If no node sits there, the support is not assigned.
