Import DWG - Bug?

[rickgraham]

Hi all,

When I import a DWG file into SU, I get the following error:

Error opening AutoCAD import file: No filename
This does not appear to be a valid AutoCAD DWG or DXF file or the file is write protected.
Import failed.

Yet, when I do it again, it will import with no problems at all!

When SU gives this message it means that you did not pick the correct scale/units under dwg import options. When SU asks for scale under dwg import options, it is really asking for the units that the original CAD file was drawn in. (Why can't they make this clearer?)
Sometimes we have to guess this... mm / inches / metres / who knows?
Pick the wrong one and you get this message. Now this message is an unhelpful load of.....it's so unclear as to it's solution it's incredible, but trust me, just try a different set of units and voila...it imports everytime.

I am having a same problem but none of the option seems working. Also neither version of .dwg file works and suddenly sketchup won't open ANY cad file, even those that used to be easily imported a while ago. Any ideas?
