As far as I can tell if you create a drawing as 1st angle, change the style for 3rd angle nothing happens unless you create some new projections. These new projections are then drawn as 3rd angle but the original projections remain as 1st angle.

that would be correct but i believe what he was asking for was how to change over his formats. I hope he was not thinking that changing the projection would change the views also. I was just pointing out that PRO-E can do across the system changes to the templets and IV can not.

The original post is a little ambiguous in it's phrasing and could be interpreted as wanting to change the projection of EXISTING drawings OR just to change the template for NEW drawings to be 3rd angle.

granted i agree with you

I had this problem too in Inventor 2013

Basically you need to have a drawing open (1st or 3rd angle) otherwise the menus relating to drawings are not available.

Then, go to the Manage tab, select Styles Editor and then you can change the settings in your chosen standard.

NB. In Inventor 2013 you can change the default template at the Welcome screen (Welcome button on the Get Started tab)

So change your style to what you want at startup (Get Started) eg. ISO mm, then go to Styles Editor and change the settings for that Style to what you want, eg. Third Angle Projection and then Save the style to the drawing. Then go to the Manage tab, and hit Save to save Styles from the current document to the Style library.
