It is proposed that there is not only a difference between knowledge and three-dimensional knowledge, but also between knowledge derived from artefacts called by different names. The three-dimensional artefacts are intermediaries or boundary objects between the past and the present, and the makers and users of these objects. Taking the differences in names and how they are linked to epistemological differences seriously and making them visible is argued to be a key to a more reflexive and productive making and use of three-dimensional artefacts.
