Processor

Intel® or AMD® processor 2.0 GHz or greater. OpenTunnel Designer is not supported on a CPU that does not support SSE2.

Memory

8 GB minimum, 32 GB recommended. More memory almost always improves performance, particularly when working with larger models.

Hard Disk

10 GB minimum, 12-22 GB depending additional installations such as Companion Feature and Companion Product.

Video

See the graphics card manufacturer for latest information on DirectX drivers. 1 GB of video RAM or higher is recommended. If insufficient video RAM or no graphics card supported by DirectX can be found, OpenTunnel Designer attempts to use software emulation. For optimal performance, graphics display color depth should be set to 24-bit or higher. When using a color depth setting of 16-bit, some inconsistencies will be noted. For more information on recommended workstation profiles for OpenTunnel Designer, see MicroStation System Requirements and Hardware Recommendations
