1. A computer-implemented method for generating a digital building model, the method comprising:
a) reading in an initial building model;
b) extracting a creator indication about a creator of the initial building model from the initial building model using a pattern recognition method;
c) selecting a creator-specific object pattern library from a multiplicity of creator-specific object pattern libraries based on the creator indication, and loading the creator-specific object pattern library in which a respective object pattern has an assigned building element data record;
d) correlating the respective object pattern with objects of the initial building model by a pattern recognition method;
e) assigning an object correlating with the respective object pattern the building element data record assigned to the object pattern as an annotation; and
f) generating and outputting an annotated digital building model, wherein the initial building model and the assigned annotations are taken as a basis for the generating and outputting the annotated digital building model;
wherein a coordinate indication is extracted from the initial building model, and in that the initial building model and/or the annotated digital building model is scaled on a basis of a captured coordinate indication.
