The COM/DCOM Server Control utility supports plug-ins and third-party programs that use the COM (Component Object Model). The idea behind the COM is to expose the core of 3ds Max so applications can invoke 3ds Max to generate images.
The COM facility is intended for application developers. For more information about applications development with 3ds Max, see the description of the COM object interface in the help file (3dsMaxSDKFull.chm) for the 3ds Max Plug-In Software Development Kit (SDK).
To register 3ds Max as a DCOM server:
Now 3ds Max is registered as a DCOM server and an instance of it can be created from any COM client.
It is also possible to register and unregister from the command line. There are two command-line options that can be passed to 3ds Max:
3dsmax -RegisterMAXRenderer
3dsmax -UnregisterMAXRenderer
