Licensing

Purchase or rent

First, you can purchase our licenses and have them maintained via an annual fee, which is mandatory when using the import interfaces for native CAD formats.
Alternatively, licenses can be rented (annual subscription). These annual fees include software maintenance.

Desktop products: Fixed seat or floating licensing

3DViewStation desktop licenses can be purchased as fixed seats or floating licenses. The 3DViewStation VR edition and the batch tool KAS are only available as fixed licenses.

A fixed license is bound to one machine. This machine may be used by different users. In practice, these are often power users who need the software frequently or users who are on the road a lot or also fixed workstations, e.g. the stations of a production line.
Floating licenses can be used on changing machines. A license manager limits the maximum number of simultaneous users. If the user ends his session, the license is released immediately, i.e. without delay.
Floating licenses are used when there are many occasional users, but only a smaller subset of concurrent users. Many database systems license by the "named user" concept. Here, every user registered in the system is simply counted. This is not the case with us.

We recommend to provide all power users with fixed licenses and the remaining users with floating licenses. A ratio of 1:5 is a good starting value: 1 floating license per 5 named users. In practice, this ratio can also be 1:3 or 1:10. However, only real operation can show this.

Web-based products: Licensing "per concurrent session" or "per server".

3DViewStation WebViewer and VisShare licenses can be purchased "per concurrent session" or "per server".
The most common form of licensing is "per concurrent session". Here only the number of concurrent sessions of one or more WebViewer servers is counted, similar to the floating model for desktop products. So it does not matter which user is accessing from which client.

This licensing model scales very well, as we do not limit the number of servers that can be used. For availability reasons, at least 2 servers should always be kept available for a large number of users. In case of extremely complex 3D CAD data (millions of parts and more) only a few users per server can be served, so more servers have to be provided. This can be realized especially well in the public cloud.

Besides that, there is the "per server" licensing model, where a server is licensed according to the number of "threads" the CPU provides. Today, 1 CPU core usually has 2 threads.
But this licensing model is rarely used, because it is quite static due to the fixed server and binding to the threads. And since we do not limit the number of users, it can overload the server if this is not prevented by the integration. Therefore, this licensing model is mostly used for visualization of single parts or smaller models and for relatively few users with little interaction.
