Recently we upgraded to Civil 3D 2012 and one of the things I was really excited about was actually an AutoCAD 2011 feature that enabled text in linetypes to always stay upright.
It's been almost two months and I thought this feature was working great for everyone until someone sent in a support request complaining that their text was upside-down. Naturally I thought they had just loaded up the old linetypes but to my surprise, when I opened the problem drawing, I found that the text was upside down no matter what. Then I saw it...the drawing had a rotated viewport which meant that the Y direction was pointing toward the floor. That was my "You gotta be kidding me" moment with this feature.
My solution? I copied our linetype file and did a find/replace switching all the "u=0"s to "u=180"s. This gives users an alternate set of linetypes to load when they've got a rotated viewport. Pretty?...no. If anyone has a better solution...please share!
