I have exactly the same problem
and it is practically impossible to work regularly
I'm using the pro version and I'm stuck
this is very very annoying
I have a small office and use I sketchup as a main software for my work
and this bugs is creating very big problems and delays on deliveries
since yesterday did not come out

I've just intsalled your updated plug-in
but apparently is not working

once Sketchup is started, a window is telling me that:
Error loading files PiGa_Richsection.rb
can not convert nil into String

ca you please help me?

thank's guys...
i'm very "imbranato"!!!!
in any case i've contacted the producer to know something more and they told me that are waiting an apy from sketchup lab.
solved the problem i have to say that this is a great plug in!!!
thanks

anybody know if there is a plug-in or a way to transform or to exchange files from Sketchup 8 versus Sketchup 7?
i've upgraded my system and my files to the new version but just discovered that my favorite plug in (sketch4D) is not working with the last version....
