Marine Design Plug-in for Rhino

Network Version Downloads

A network license is available for Orca3D. Note, however, that unlike the Zoo for Rhino it must be purchased and the software installation is different than the standalone.

If you have purchased a network license or are updating your current network version, please begin by reading the Installation Instructions. They must be followed carefully in order to have a proper installation.

Orca3D Network License Requirements

Orca3D Network License Requirements

You will need to select a machine in your network to act as the Orca3D network license server. Although this can be any machine in the network, it is advisable to choose a machine that is always running so that the Orca3D license is always available. Preferably the server will be connected to the Internet for license activation and updates. If not, manual activation is possible.

You must have administrative privileges when installing the network server.

Network access and Firewalls

At activation time and at periodic intervals, the Orca3D Network Server will require a connection to one of the CopyMinder internet servers to validate the license. This will also be required if a problem is detected with the license. At the time of writing, the servers are as follows:



Secondary (limited functionality):

All communication is done by HTTP over port 80. It is important that any intervening firewall or proxy does not modify or reformat the data being exchanged.

Running protected programs (network installations with CMServer.exe)

There are two aspects to consider; the connection from the clients running Orca3D to the machine running the Orca3D Network Server (CMServer.exe) and the connection from CMServer.exe to the CopyMinder webservers.

Network Clients

The client computers running Orca3D must be able to connect to CMServer across the local network, at the IP address and port you configure when installing / starting CMServer. Please see also “Autodetection of CMServer by network clients” below.


CMServer must be able to connect to the CopyMinder servers, exactly as described in the section above. Additionally, it must be able to receive communication from the network clients on the IP address and port it has been configured to listen on. Your firewall(s) must allow both TCP and UDP traffic through to CMServer. CMServer includes a small utility which it launches and attempts to automatically configure the Windows firewall to allow this.

Autodetection of CMServer by network clients

Clients auto-detect CMServer by performing a multicast on whichever port you configured CMServer to listen on. Your firewall(s) must not block traffic destined for this address/port, or auto-detection will not work.
