Select all objects in a layer

Hi,

First of all, I'm fairly new to grasshopper, have been messing around with it for almost two weeks and has already changed my workflow in quite a bit.

Before I started using GH, I had a brief experience writing Lisp routines for autocad. That sums up my scripting experience really.

I'd like to know if there is a way to get all objects from a layer in rhino and use them in GH. If I draw new geometry in that layer, the script "live updates" and that new geometry is automatically used in a GH definition.

For instance, let's say I have a circle and I draw cutting lines in the layer "Parcels". Those lines would cut the circle in diferent parcels withou me having to do the "set multiple geometries" routine everytime I feel like changing something.

I´ve found this script, but just can't manage to adapt it to the script in GH.

Any thoughts? Is it even possible?

Thanks in advance.

David,

Is there a piece of example code that can be used to detect a layer object change for c#?

Rodrigo,

I put a definition together which is kind of a hack but works well for me when adding new objects to Rhino space without selecting in GH. Not live update, but uses a toggle.

To test, try adding new points to rhino space and then hit the boolean toggle. The object should be updated.

Requires Horster reference tools.

Also, I haven't been able to download the new GH yet, so this is made using the old one.
