Hi as the topic says i have problem exporting model from sketchup to .stl and i'm using the official plugin..
Look at my pictures to see my problem..

sketchup.jpg 1 st picture is how it looks in Sketchup
makerbot1.jpg 2 nd picture is how it looks when loaded into makerbot desktop

printpreviewandresult.jpg 3 rd picture shows it in the print preview and this is the result when printed

What is causing this error ? It seems to occur at random places and even in very uncomplicated designs !!

// Cheers
