This video shows the editing of the Mies van der Rohe's Tugendhat house plan into a series of layers and objects that fit the interests of the designer looking at the plan. The model once transcribed into the maximal line representation can be used in a straightforward way for analysis and synthesis in any vector-based software. Here the columns and the doors of the plan are reclassified and edited by shape rules that are drawn on the spot to automatically pick them up the and clarify the drafting conventions specifying their appearance.
