Grasshopper
EleFront
EleFront is an add-on that allows the user to bake geometry, annotations and blocks with user defined attributes and or Rhino attributes. Rhino objects can be referenced and filtered dynamically, to be used in Grasshopper.

Add Attributes to Geometry directly in Grasshoper without Baking?
Hi,
does anyone know if there is a way to add attributes to geometry directly in Grasshopper? The only way I figured out so far is to bake the geometry with its attributes into Rhino and then reference it back into Grasshopper.
I am aware of the BIG concept using multiple Grasshoper scripts and Rhino files as data exchange platforms. But for not-so-complex projects, I feel a component that takes geometry&attributes as inputs and gives extended geometry as output could be useful.
Or am I missing something here?
I attach a file with an attempt to model reinforcement bars for concrete structures. The idea is to create one single rebar, and then aggregate a number of them into a "compound" object.
Best regards
Stefan

The problem with assigning attributes to grasshopper geometry is that object attributes are not consistently preserved while passing through grasshopper components. Also, any modifications made to these attributes are applied upstream, which goes against grasshopper logic.
To mitigate this, the latest EleFront has a full suite of components to create and modify attributes independent from host geometry.
You can filter these attributes by certain values, while filtering the geometry in parallel.
All you need to do is maintain the attributes in parallel to the geometry. This approach will give you full control over which attributes to inherit from which objects at any geometric operation.
