DWG files are those created by AutoCAD and other similar programs, so they are very commonly used in their work by architects, riggers and designers in general.
For all of them it can be very practical a tool like FlashDWG, which allows you to convert DWG design files directly to a Flash animation (that is, in SWF format). This allows you, for example, to publish this design on a web page.
You do not need to have any Flash viewer, since FlashDWG already comes equipped with its own viewer that allows you to see the results, keeping all the elements and details of the original DWG in the resulting Flash animation.
You can free download FlashDWG 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
