Error when rendering large complex models

Problem

When rendering large complex models, this type of error may occur:

"Unable to load dynamic link module in [built_ins] platform".

The possible reason that might cause this message is that MicroStation may be hitting the maximum user-mode virtual address space (set by the OS) when generating the temporary files during the rendering process.

Solution

If the system has more than 1 GB of physical memory, try increasing the maximum user-mode address space as well as the alternate user-mode address space.

Add this switch to the boot.ini file.

/3GB /Userva=<(><<)>value>

Notes:
- IMPORTANT - READ MICROSOFT'S INFORMATION ON THIS BEFORE CHANGING!!!
here is a link:

- Switch /3GB - Enlarges the user-mode virtual address space to 3 GB and restricts the kernel-mode components to the remaining upper 1 GB.

- Switch /Userva=<(><<)>value> - Specifies an alternate amount of user-mode virtual address space (in MB) for operating systems booted with the /3GB parameter. The value specifies the amount of memory (in MB), for user-mode virtual address space. This variable can have any value between 2048 (2 GB) and 3072 (3 GB) megabytes in decimal notation. Windows uses the remaining address space (4 GB minus the specified amount) as its kernel-mode address space.
