Issue I255 [med-high,enhancement,partlyimplemented] Loading IOB/PA files from Windows explorer file associations or command-line. As of SIMION 8.0.4-TEST17, IOB and PA files can be loaded from Windows Explorer file associations or from the command line. Examples: simion.exe "c:\Program Files\SIMION-8.0\quad\quad.iob" simion.exe "c:\Program Files\SIMION-8.0\quad\quad.pa#" Requested by theo-20061016/20070423/20070426 and tbraun-20071008. Related (not implemented) Also, can you make .iob files to list the names of .pa files the include either when looking at the properties of the .iob file in explorer or when placing the mouse cursor on the file? This would be useful to remember which pas are included. I guess this is one reason why you also have the doc load which should have the same name as the iob file? -- Possibly. For example, if you right click on a PDF file and select "Properties", it shows a tab with PDF-specific properties. Related (not implemented) Load FLY2, REC, and other files too. Largely implemented in 8.0.4-TEST17/18.
