I’m working with some IFC file I’ve been provided and I’ve managed to reduce their size by going through Trimble connect and saving out as TrimBim which has been a god send. However some of the file have more detail than others. I don’t need the super detail that they have and although I’ve been able to isolate a lot of things on Tags, there are some which are all in the same instance/tag. So I was wondering is there a selection tool that allows you to only grab object over a minimum size. For instance nothing smaller than 500mmx500mm. Can’t find anything, but I’m sure someone know a neat trick or a plugin that I’ve missed.
Thanks
In Sketchup objects are 3D… so better to give the 3rd too 
However, the diagonal of the entities bounding box can be also a good representation of the size. So I made a quick code snippet which can remove the entities from the selection, which diagonals are smaler than a parameter (default is 500.mm).
def selmin( mindiagonal = 500.mm)
model = Sketchup.active_model
sel = model.selection
sel.to_a.each{|e|
next unless e.respond_to?(:bounds)
if e.bounds.diagonal < mindiagonal
sel.remove( e )
end
}
end
Usage:
Open Ruby Consele and copy paste the snippet into it.
Select the objects in a question
Type into Ruby console:
selmin (For default 500.mm)
or e.g.:
selmin 700.mm
or e.g.:
selmin 25 (Where 25 the diagonal in inches)
and hit Enter (Return)

Heya, sorry got distracted last week with a deadline, thanks for this little code, I will give it a go
