Hi @Matthias
May I know how to find and fix pattern intersection issue?
as this sample case, I using Klayout to create a polygon as this one.
I can open it in Klayout, but I can't opening or edge into other tools.
Look like I make a pattern have intersection to make some issue in other software.
Do you have any idea or solution to fix / find it ?

Hi @jiunnweiyeh
Basically, such polygons are valid ones in GDS, but some foundries or processing tools have trouble with these.
Another problem is self-overlapping or short-segmented paths like these:
DRC has a feature to find them:
To fix them, you can merge everything. For example in DRC:
However, that may be time consuming, flattens your layer (unless you use deep) mode and merges multiple polygons into one if they touch.
