Drawings, 1st Angle or 3rd Angle?

[komatias]

Which do you prefer to work with? And do you use dotted lines for hidden features?
I was taught engineering drawing in the 80s and so learned mostly in 1st angle projection but as part of the course we were required to be able to recognise and work in 3rd angle.
For most things I will now work in BOFP (Back Of a Fag Packet) but anything which requires some clarity of features I revert to 1st angle.

Whichever your organisation works in. My mind always works in 3rd angle. French and Norwegian companies work in 1st.
Either way, always pays to look at the projection symbol.
Hidden lines are always dashed, not dotted. And you never ever ever dimension them.
