Hey there!
We would like to implement your newest feature of selecting a geometry in the 3d view and further process this in grasshopper. Because the grasshopper calculation can only be made when the âfacadeâ is selected, we thougt of splitting the input (geometry and data) and selection and the output in two pages. But we are stuck at this stage. How do we define the pages in our controller and how do we make a geometryview that is only for selecting the facade without processing it? (processing should be done in the second page)
This is our state of the script:

Thanks for your help!
The geometry selection works and we got 2 separate steps now, yeah!
