Beyond PDF and DWG, what other drawing formats does BidScreen XL accept?

The full list per the manual: AutoCAD DWF, DWG, DXF; CALS (.cal); Intergraph Vector (.dgn); DjVu (.djv, .djvu); Hewlett-Packard HPGL (.plt); LEAD CMP (.cmp); JPEG; PDF; PostScript (.eps, .ps); TIFF; Windows Bitmap (.bmp); Windows Metafile (.wmf); plus PNG and an All Files fallback. If you have a vector version, use it — measurement is faster and more accurate than clicking on raster pixels.
