This would suggest that 1 blender unit equals 100 cm, and not 1 mm, which the documentation says.]]> quano 2011-01-29T13:10:23-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=23172&th=4439#msg_23172
The documentation deals with an example file using an STL which is in itself dimension less. Here I expect, units are copied one to one from blender to the file.
Only for STL does the upload interface require you to set units, in that case millimeters, as assumed for designing in blender to shapeways/stl.

Ps. this post is just to clarify and for any future searchers.]]> virtox 2011-01-29T13:51:49-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=23346&th=4439#msg_23346
You'll also avoid some spurious upload errors in this way: in rare cases the numerical accuracy will 'weld' close-by vertices together on models that use meters as their site unit.

y: 1,000
z: 1,000

or one unit is 0,001 ???]]> speedyexe 2011-11-09T20:27:09-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=38276&th=4439#msg_38276 speedyexe wrote on Wed, 09 November 2011 20:27
one units of blender in program is in scale? (...)

Scale is scale.

1 "blender unit" & a scale of 2.000 = 2 "blender units"
5 "blender units" & a scale of 2.000 = 10 "blender units"
