Pangolin
(by Consteel)
Provides components for building structural models to be analysed in Consteel, and two-way connection between Grasshopper and Consteel.

Using Pangolin you can create complex steel structural model definitions that include details such as beam haunches, highly configurable cold-formed sections with stiffeners, surface loads with load transfer surfaces distributing them onto beams, load combinations made up of loads in load cases, and so on.

The created model then can be saved out as a file for later usage or sent directly over to Consteel by the connection component, for analysis with Consteel’s unique calculations.

Currently supported objects:

  1. Geometry: Lines, arcs, polygons
  2. Structural members: Beams, plates, supports, rigid bodies, diaphragms, link elements, haunches
  3. Sections: more than 7000 predefined from Consteel section bank, or custom defined by section macros, including cold-formed sections with stiffener definition support
  4. Custom structural attributes: release stiffness model, support model, material properties
  5. Loads: Nodal, line, uniform and linearly changing surface loads
  6. Load configuration: load combinations, load groups, load cases, load transfer surfaces
  7. Organization: Layers, and structural groups
  8. I.O. : Load from file, load from Consteel, save to file or Consteel
  9. Integrated parameters for unambiguous definitions, avoiding the use of nebulous generic parameters

Other noteworthy features of Pangolin:

  1. Integrated implicit data conversions: eg.: connecting a beam created with Pangolin into a Grasshopper plane parameter will automatically get the beam’s local plane, connecting it to a curve parameter will get the beam’s reference edge and so on.
  2. Detailed component error messages and warnings: every component gives out detailed error messages if it is incorrectly used, and warnings, when the usage is not incorrect, but possibly problematic.
  3. The plugin is runnable without the presence of Consteel, free of charge, including saving export files for later consumption. Consteel is only needed for performing the analysis and design on a model.
  4. The exported file will be useable in the upcoming Steelspace cloud solution.
  5. Iterative modification: if a model is sent over to Consteel multiple times during a work session, the model will be modified according to the changes instead of duplication. In later work sessions, the components can be synchronised with the actually open Consteel model to allow for continued modifications after Rhino and/or Consteel was closed and reopened.
