and around v.5 they changed from ACIS to ParaSolid (which is owned by the 
competitor EDS (www.eds.com) that make Unigaphics and Solid Edge). I was told 
the transition was not smooth for the endusers :-).

The standars formats are *.slddrw *.sldasm and *.sldprt (drawing, assembly and 
part files). Slddrw is a parametric dimensioned 2D representation of a part 
or assembly file. Sldasm is what Phrostie describes (productfile) also 
paramteric.
the parametrics will be lost if saved as x_t and x_b (like when you make a PDF 
file which will not automatically update when you edit the source file). 
Therefore if you only read x_t and x_b users will have to save a copy to that 
format, and could instead save as PDF, TIFF, SAT (ACIS), DWG, DXF, that can 
be read by other viewerproducts. Or have the user make an executable 
e-drawing which can be excuted in windows

sorry no. but I think e-drawings is/have been available for linux
