Recently I was working to create GHPython plugin for welds' design to speed up steel structures design in Grasshopper. There is no other software used beside Grasshopper. For graphs and text display I used Conduit plugin. Now I'm switching from IronPython to C#, so it'll be much easier to maintain all components' code and to test it all. Unit tests were made inside components with unittest. It'll be much easier to do testing and test code coverage in C# with Visual Studio, xunit and other tools. Contact: w.radaczynski@gmail.com
