Hi,
I start learning dynamo, and I create my first file. i want to create an element on ich intersection between walls and ducks.

to do it, I creat one list with all walls and one with all ducks. Next, i want to intersect all geometry off the two list.

using " geomatry.intersect" dynamo intersect the first element of ich list, next the second one of ich list,…

But with “geomatry.intersectAll” is the same result. in my exemple I normaly have four intersection but dynamo only find two.
