Node Parameter

WARNING

GSA-Grasshopper plugin [GsaGH] is pre-release and under active development, including further testing to be undertaken. It is provided "as-is" and you bear the risk of using it. Future versions may contain breaking changes. Any files, results, or other types of output information created using GsaGH should not be relied upon without thorough and independent checking.

Description

In GSA, Nodes are the only objects containing spacial geometrical information (X, Y, Z coordinates). The Node numbers are then referred to by Elements and Members in their topology lists. This is possible because everything belongs to a single model, and the information does not need to be duplicated in the Elements and Members.

In GsaGH, on the other hand, all parameters (Nodes, Elements and Members) exist independently from each other. For instance, an Element1D in GsaGH internally keeps a copy of its start and end points. You don't need to know about this, the plugin takes care of that for you in the background. You almost only need to use Nodes for defining supports.
