Open Source CrossPlatform Repo – Develop for Revit/Dynamo & Rhino/Grasshopper from a Single Code Base

From GitHub:


This repo hosts the sample code written for the BiLT EUR 2018 Cross-platform development : from Revit/Dynamo to Rhino/Grasshopper and the web hands-on labs. The lab was accompanied by a lenghty handout that is available on the BiLT website for registered people.


Be a reference, source of inspiration & education for others.

What is it

It's a sample of how to build cross-product libraries for AEC apps, with a focus on
  • re-using as much code as possible
  • demonstrating some SOLID principles in action
  • supporting as many apps as possible

The solutions is made of up of 2 things : a common library and specific application implementations.

Crossplatform Library

This is the shared functionality that is product-agnostic & re-usable.

It holds the
  • geometry & BIM element definitions
  • interoperability/conversion routines

App implementations

Distinct applications that bring the  Crossplatform.Libraryto  each platform :
  • Revit app
  • Dynamo app
  • Rhino app
  • Grasshopper app

What does it do


It's a bare-bones geometry-sharing library, with definitions for
  • Point
  • Line
  • Wall

You can convert To & From the  Crossplatform.Geometry  objects in Revit, Dynamo, Rhino & Grasshopper. You'll also note that not all conversions are straight-forward : there's no Wall in Rhino, so that conversion shows how to think about translating non-compatible objects.


All has a simple  WhoAmI  command that has a single implementation for all products, but still manages to be a bit product-specific.


developed over 2 days before BiLT, so don't expect crazy-good code, I'm aiming for decent here
this is not in active development, but modifications (pull requests, PRs) are welcomed if they add to the educational value of the repo
