Thanks for your help in advance, I am creating composite content, stacking polygons together from different 'surfaces' then clipping. This works as expected but it is almost exponentially creating additional vertices. This is an issue and as a result I need to generalize the output. Unfortunately when I use the generalizer tool the output geometry reports lots of invalid outputs, mainly 2d self intersections. Does anyone have any suggestions to help.

Many Thanks

Hi @olivermorris,

Changing the generalizer algorithm or settings may prevent the creation of the self-intersections.

The GeometryValidator transformer can be used to repair the self-intersections.
