How can I check for "type" in IronPython?

Hi @cutmeat,

Try this to filter the points :

Get list of points from DWG selection

Hi @Claus, You can do like this in python : import clr clr.AddReference('ProtoGeometry') #from Autodesk.DesignScript.Geometry import * from Autodesk.DesignScript import Geometry as geom items = UnwrapElement(IN[0]) points=[] for item in items: if isinstance(item, geom.Point): points.append(item) OUT = points Or with the List.RemoveIfNot node : [Points]

if isinstance(obj,geom.Point) should maybe be replaced by if not isinstance(obj,geom.Point)
