Hello James,

After some problems in my life or with my wife, I had to find a new orientation - I think a well known problem. Now it's getting better and better and I see the light at the end of the tunnel - I hope it's not a train;-)

To your problem:

At first: I think removeduplicate needs a second input - a tolerance value, but that won't solve the problem alone. I suspect that this factory don't give a geometry list back - it works directly to the geometry database. So we have to use a workaround - 1. write the input to the database. 2 call the factory. 3 delete the input list (otherwise the database locks removing). 4. commit the factory 5. get the left objects (singletons) back and copy them in a list. 6 delete the singletons also from the database. 7 give the list to the output.

It's only a first idea - give me some days please and I will have a closer look.

I hope you are well and remain with kind regards!
Karsten
