+5FME Desktop 2022 Build 22311: The AutoCAD “island detection style” property appears not to be available in FME,
I wanted to filter based on “island detection style” type (normal, outer, and ignor) but appears that this property is not available in FME
The dwg file is attached

@jamal In Autocad you have the variable HPISLANDDETECTION.
In FME it is translated to autocad_hatch_style with the same values HPISLANDDETECTION (System Variable) | AutoCAD 2016 | Autodesk Knowledge Network
@nielsgerrits Hatches in Autocad can have donuts (inner and outer boundaries) but be displayed as area (outer boundary only). FME reads them as donuts as it detects all the boundaries and you have to remove the inner ones.
The term for these geometries in FME is "donut". If you expose the attribute fme_geometry you can test or filter on "fme_donut".
+5But how to identify if the hatch is normal, outer or ignore type?

+5Thank you for the help.
Right. The auotcad_hatch_stype appears to store the hatch type as below:
0: normal
1: outer
2: ignore
