I am experimenting with using VisualARQ Dynamic Blocks for naval architecture. Currently, I’m working with a concept that takes a planar path curve and a deck surface as geometry input parameters, along with a bunch of numeric parameters, to generate a curved bench that extends to the deck. I think it makes the most sense to make this a VA object by creating a Wall grasshopper style, considering that the input is a plan curve that I want to be able to manipulate.
So, I go to the GH wall style wizard, select the GH doc, and proceed through the steps. But, I am having some issues with the input parameter for the deck surface. This is the behavior I’m experiencing:
- (GH) Geometry Param → (VA) Doesn’t show up in Param list at all
- (GH) Surface Param → (VA) Shows up in Param list with type “Unknown”, Can’t any pick object
- (GH) BRep Param → (VA) Shows up in Param list correctly, allows picking, but won’t allow picking the surface, but I can pick a closed BRep.
The VA docs suggest that the Surface and Geometry Params should both be a valid input params for a Grasshopper Style. Further, I would think that the single surface would be able to be cast to a BRep, so it is unclear to me why I can’t select the surface.
Can anyone offer some insight about how these input params are meant to work?
Here are the documents I’m working with:
