Dear all,

Dassault have done a cracking job on this.
Most of the command aliases are the same as AutoCAD. e.g. l[space] for
line, m[space] for move.
DWG and DXF compatibility back to release 12 (which is more than you can
say for AutoCAD 2010).
No Express tools (although it does have "Express" layer tools which
where what you wanted from the Express tools anyway).
No Autolisp, ARX, etc. But LT didn't have this anyway.
