This video continues the editing of the Mies van der Rohe's Tugendhat house plan into a series of layers and objects selected by the designer and includes drafting processes that are not easily captured by classifications of ready-made architectural parts. Here the vignette shows how a corner detail can be selected ad hoc by the designer and inserted in a shape rule to specify how the interior lines within the wall detail can be cleaned and how this rule can be used to apply to all corresponding parts of the plan.
