To date, Reality Models have been used primarily to provide context for their engineering counterparts. Advancements in the production of Reality Models have greatly improved the fidelity of these models, but their value has been somewhat limited by treating these models as monoliths. With the Acute3D ContextCapture tools, it is possible to create a reality mesh that very accurately represents an entire city, plant or other large infrastructure project. However, cities are made up of many parcels and plants consist of many components. The reality model may capture each of the parcels or components accurately, but without some method to distinguish the parcel or components from the rest of the reality model or tie them to their underlying engineering or GIS data, the value of the model is limited.

MicroStation introduces the concept of using engineering or GIS objects to spatially classify a reality model into a discrete set of volumes that represent those objects.

The Reality Mesh Attachments dialog is used to attach and manipulate reality meshes. You can also spatially classify reality meshes so as to be classified by and associated to design or GIS data.
