"However, this wasn't a gradual process but we have experimented with many things at the beginning. For example, in the initial version we used OCC's document framework OCAF and its viewer but after a year or two we got into a dead end because documentation about OCC was very poor and we couldn't get it to work to extend OCAF with our own feature types. So, we decided to only use OCC's modeling capacities but develop our own application/document framework."
