Pipeline by selected objects?

Grasshopper

Hi,

In Grasshopper, instead of using Pipeline to get the objects from a layer is it possible to use something to get the objects that are currently selected and have them as input?

Thank you!

Wow, this is so useful for quick geometry evaluation, checking areas, sketching. And fun to have such instant input.
Should be part of the Pipeline component. In GH2 maybe?

Fantastic solution!
Anyone knows how to translate this to python SDK mode?

Yes, I can only state once more that Pipeline Selected could be very useful, kind regards!
