Just upgraded to AC Map 3D 2010 (yeah I know 2011 is out already) - On a daily basis I open multiple new drawings and the first thing I have to do is set the coordinate sysyem to the one that we work in (NY83-EF). 
Trying to figure a way to automatically have the new drawing set in my coordinates. 
 
Can anyone advise me on the best way to do this?  Define a lisp function to automatically?  Go through the cui and create a button to accomplish the task (macro) ? 
 
 

You can set the CS in your drawing template or you can use the LISP function - e.g.:
 
(ade_projsetwscode "LL84")

Thanks - After posting my question - I found the "tip" that suggested that LISP funcion.
