Topic: Export all Blocks to indv. files zoomed to Extents

[Antisthenes]

this script (copy save in *.rvb file) adds the command ExportAllBlocks to Rhinoceros 4 (  and zooms extents to them so you can see the thumbnails in explorer thumbnail mode after having CADpreviewImage installed
http://www.rhinocenter.fi/tools.php
http://www.rhinocenter.fi/tools/Rhino%20Preview%20Image.exe

this views DWG files and thumbnails too and is very useful to dig out some stuff of DWG files you would never know was there i found
blocks within blocks within blocks on one file that was 32 mb.  )
