At least we only have "simple" rain here. So much about global warming.
No, Gaieus
Here in the north it goes: Higher temperatures in the Arctic> more evaporation, more winds> more rain
As to importing DWG files, a valid file should import OK, but SU ignores many object types, especially those created by AEC applications like AutoCad Architecture. Those should be "Exported to AutoCad" prior to sending you the file. Cleaning the file of unnecessary geometry makes it import faster, but should otherwise not be necessary. There seems to be some limit to file size, though, I have read somewhere that at somewhere bigger than 10 Mb the importer begins to choke.
Note too that the new AutoCad 2010 version that came out this spring has a new file format that is not yet readable by SU. So if the person who is sending you files uses that, they should save the file in the 2007 format or older.
An intermittent problem with the same file might indicate some other problem, like a problem with a removable disk/memory stick or a network glitch, if the file resides on a server.
