Hi David, yes the model runs.
The reason I believe the reports "disappeared" was because the specified year does not stick sometime. It could answer might have been covered elsewhere. The Sketchup GUI corrupts OS Measures. After running a result of "save as". model with added OS Measures you cannot alter anything with the Sketchup GUI or the .osm becomes corrupt and PAT will likewise fail.
Thank you, Matt Best Regards, Matt
