Once® CAD/PLM is our core product and sets the standard for best practise reuse in engineering in your company. Once® is your database and the repository for all multi-discipline tags, parts, BOMs and in-depth electrical engineering. Once® makes drawing production, document production, procurement and project processes more efficient. In essence, a tool that is tailored to support your PLM process. 

It doesn't matter if you prefer to work in the CAD tool itself and use our Once® toolbar, or directly from the Once® CAD/PLM tool and open your drawings from here. With Once® you have 100% data consistency across your products and projects. We offer several tools based on the same engineering information: The Portal, Once Go and Once 360 are all based on the same single-source of information. This way you enter data only "once". See our Once CAD/PLM datasheet for more details on the products.
