OK!  I understand what first angle projection is, but!  Why would anybody want to use it?  I can find no practical application.  It is not intuitive like third angle.  Does anybody know the history?  Was it used before third angle projection?  Why is it in use in Europe?

I am like you Bob, why would any one use 1st angle! I find it difficult sometimes and particuarly when looking at a couple of drawings and one is in 1st angle. It is a bit like the Americans using imperial!
