1Des is a relational database system that ensures accurate data entry from where all documents are generated. This means that data lives in ONE place and changes only have to be made in ONE place and all documents will be correctly updated.
1Des has an internal drawing editor that saves documents in DGM format but can also save all DGM documents as DWG or PDF formats without the requirement of any additional software installed.
