As I mentioned in a reply the bug report (it is ridiculous and should be closed.) Some of the coordinates are in MILLIONTHS (or smaller) of inches ! One near the end has a -16th exponent: points << Geom::Point3d.new( 4.194623966922387e-16, 0.20218771239100042, 65.51048909232898 ); That is about 42 femtoinches. In other words, 42 millionths of a nanoinch ! (42 millionths of a millionth of an inch.) Does the OP (@torel) understand that SketchUp has an internal coordinate tolerance of only 1 one thousandth of an inch ? Why would anyone want to be passing SketchUp coordinate floats with up to 19 decimal places ?

Ahoi, as some of you already realized, project Ropefall has closed doors. This means no new licences will be given away. Maintenance support will remain available in the maintenance period (a year after purchase). Thanks for your support so far! Balazs

Yes you do not need to search among ALL the house's entities, IF you know the door's definition. IF you do, then simply look in the definition's instances() collection. If there are multiple door definition's, then you can iterate the model's DefinitionList collection, testing each definition for some identity (name value, or attribute in an attribute dictionary, etc.,) ignoring any definitions that have no instance, ie: !defn.instances.empty?
