In the US is it pretty standard to use the "third-angle procjection" style to represent a 2D view of a 3D object?

RE: Projected views
Also is there a standard way of showing dimensions in third angle projection? Should you or should you not double show the same dimension in different view points?
I know all of this is very dependent on the shape and complexity of the object. Im just trying to develop a standard operating procedure for CAD drawings that can be uniformally used over all drawings.

If its a feature that only shows in its "normal" projection, consider an auxiliary projected view. But again, that's the only place the dimension for that feature should appear. However, all care should be taken to avoid dimensioning the feature to its hidden lines in the view where its obstructed by the rest of the part. Is this a hard and fast rule ? Well after referring to the ASME Y-14.5 dimensioning standard, you must decide.
I use the "Drawing Requirements Manual" by Global Industries as my go-to interpretation of the standard. It's around $200, but it quickly paid for iself in clarity and quality and consistency of delivered product, and our whole department uses it now. FAR cheaper than doing up a manual from scratch.
There- that's kind of the go in a nutshell. BTW- if a view is there and doesn't have a single dimension or note attached to it, strongly reconsider whether that view is remains in the drawing. Good luck and let us know how it goes !

Uhmmm, that is 3rd angle projection. You might want to check wikipedia on 3rd angle and 1st angle projection. Simply refers to the location of top, front and right side views.
