the examples from back-u3d.mkiv fail to work with latest beta (rectangled "undefined" message appears instead of annotation), but if "\textwidth" is replaced by "in" in the tex file 3D annotations appear OK.

in the latest minimals (2012.09.06 23:03) the following example from back-u3d.mkiv fails to work

\useexternalfigure [test] [test.prc] [width=0.5\textwidth, height=0.5\textwidth, display=u3d:myset:display:1, controls=u3d:myset:controls:1] \placefigure[here]{3d test}{\externalfigure[test]}

while after getting rid of \texwidth the following does:

\useexternalfigure [test] [test.prc] [width=3in, height=3in, display=u3d:myset:display:1, controls=u3d:myset:controls:1] \placefigure[here]{3d test}{\externalfigure[test]}

Is it a bug of the example got wrong with some changes in ConTeXt.

It should work when you use “width=\the\dimexpr\textwidth/2\relax” or “width=\the\dimexpr0.5\textwidth\relax”. Wolfgang
