hello
as far as what I've read, spatial joins & model builders arn't easy to handle...

My problem is, that I want to make a spatial join (point to polygone) by using aggregationmethod 'sum' - does anybody has experience with this? I havent found a solution so far...
Thanks

Are you looking to get the sum of a field in your point feature class into your polygon feature class?  For example, if you have a Cities feature class with the field Population, and a States feature class.  You want each state to have a field that represents the sum population of all cities that are within that state?

Take a look at the Tabulate Intersection tool.  This will create an output table that you can join back to your polygon feature class, and then calculate over the summed values.
