Hello
Has anyone done the "Try to change it so the bigger rectangles change into an ellipse of the same dimensions and color." part of the comparisons tutorial? I'm sure its pretty simple but have made a mess of it so far! Have included the attempt.

Regards Matthew

   Hello Matthew,

   a cull node takes the original list and uses the compare nodes list to eliminate all false values. So connect your original list to the list and the compared list with the booleans values to the booleans list port. The resulting list is the list you want.

   hello and thanks for your reply Lucas

   I think i have yet to understand how nodes work and inter relate before being able to work this out. At least I knew a cull node was probably needed. Not sure how to use the resulting list resulting from the cull.

   Hi,
   i think you make it more complex than needed. I included an example with a subnetwork containing multiple shapes. The node that changes the shape is a switch node with a index (0 being a rectangle 1 being an ellipse).

   Yes, done finally, thanks for this, it seems a long leap, but it is making more sense now.
   Regards Matthew
