Understanding the architectures of complex system, e.g. enterprises, is greatly facilitated by using graphical views thereof. These views result from the application of an underlying viewpoint to a comprehensive architectural description. The viewpoint thereby describes, which architectural concepts should be visualized in which way. The creation of views that consistently represent the enterprise architecture (EA) from a specific viewpoint, is a challenge of ongoing interest in EA management. In this paper, we present a technique that can be used to create views consistent to arbitrary architecture viewpoints and show, how this technique is realized in a prototypic tool. Central constituents of the tool are a model providing the graphical primitives for describing visualizations (called visualization model) and a model-to-model transformation reifying an architectural viewpoint.
