If I select three entities in Rhino with the Geometry Parameter!

So, I have the 3 items, one is a Point, the second one is a curve and the last one a Solid = BRep.

So I have a list with these 3 items, how can I select only the BREP, in other words, how can I filter the list and find the only Solid = BREP.

Thanks for your help!

With the List Item component.

Thanks Luca, I like your solution, but may I add something new, how about if you do not know the INDEX number of the Brep? How can you filter, find the BRep?

Thanks!

Provided you don't have a closed Planar curve you could simply pass the geometry list into a BRep Param component which will Error when trying to convert the curve and point to a BRep, but the output will only be the BRep. If it is a closed planar curve then this will be converted to a planar srf. Otherwise you could use something similar to this: http://www.grasshopper3d.com/forum/topics/extracting-a-specific-ite...

I think this is the best I can do.

Thanks Danny!

This is a slightly modified version of Danny's function.

I have a slight different problem to the same topic.

I have 3 sets of each 3 items. In the first set the item is in position 2 in the second set in position 3 and in set 3 in Position 1. How can I erease the non needed balance?

It might help that the not needed lines are always equal but not overlapping.

This would be applied in a further instance to 1400 triangles with each 3 sets.
