The programme start load drawing fonts,shapes and many other things,then regenerated layouts and model and autocad 2010Lt programme stop moving. Some dwg file load to 61% or 82%,then programme stop moving. Same dwg files i try open in Autocad architectual desktop 2010 version and the same issue. But in later Autocad and Autocad Lt (i try in Autocad 2007, 2008 and Autocad 2008Lt versions) versions these dwg files opened without problems. I saved this dwg file in later versions ( 2000,2004,2007) - same isue. After try other method. In latest version of autocad open dwg file,then copy some drawing elements (lines) and past into a new dwg file,save it. I try open this new dwg file in Autocad 2010Lt,and its opened. These drawings came from other architecture company and i think newest autocad 2010 version programmes don't recognize some elements of drawing. I worked with many companies and never to face the issue with such problem. Can tell me some, what is the problem???
Excause for poor english.
