If you open an Architectural Desktop 2005 file in AutoCAD LT 2005, add 2-D content, save the file from AutoCAD LT, re-open the file in Architectural Desktop 2005; do you lose the original 3-D content from the original Architectural Desktop 2005 file? In other words, is the transfer of 3-D data a one way proposition? What about if we substitute AutoCAD 2005 for AutoCAD LT 2005? Same result?
Thanx in advance.
