Collections of mathematical models are a historical evidence for “notion” (comprehension by experience), they are a cultural heritage and in recent years appreciated as scientific sources. Since the models are often hidden in single Institutes, it is rewarding to make them accessible via online research. In DAMM (Digital Archive of Mathematical Models) we used the latent 3D-Web-technologies to compensate the lack of physical presence. This approach facilitates virtual cutting and the connection of material models with computer algebra systems.
