When you use images in jpg, png or pdf format context still uses a lot of tex
code where you can use this form of assignment because the values are
assigned to another dimen register in tex where this is valid.

\starttext

\newdimen\mydimenregister

\mydimenregister=10pt

mydimenregister = \the\mydimenregister

\mydimenregister=\textwidth

mydimenregister = \the\mydimenregister

\mydimenregister=.33\textwidth

mydimenregister = \the\mydimenregister

\stoptext

When you insert a 3D graphic in your document the values of the width/height
keys are read by lua which can’t handle with this assignment, what can be used
in this case are only absolute values like 10pt and with \the\dimepr… you can
do this even with relative value, e.g. .5\textwidth.

Maybe Hans can add some code which checks the argument to avoid this, e.g.

  if <argument> == "fit" or <argument> == "broad" then
      return <argument>
  else
      return "\the\dimepr<argument>\relax"
  fi
