This Custom Block filters out a point map by excluding the result of the points near CAD faces.

Used to filter out stress concentrations that appear on boundaries, which are typically simulation artifacts rather than real structural hotspots.
Uses the Keep Out Distance (KO distance) to define a buffer zone around the CAD faces — any points within this distance are excluded from the output point map.

Name	Type	Description
`Point map`	Scalar Point Map	Point Map
`CAD faces`	list<brep_face>	CAD Faces
`KO distance`	Scalar	Keep Out Distance - The distance around the CAD Faces
`Region`	Choice	The region you want to filter — `Outside` keeps points with distance > KO distance, `Inside` keeps points with distance < KO distance, `Boundary` keeps points with distance = KO distance

Name	Type	Description
`Filtered PM`	Scalar Point Map	The new point map using the filtered points and values
