Feature Types
XFM features can be seen as objects with geometrical and alphanumerical characteristics, where the geometrical part is represented by DGN elements. Unlike plain MicroStation, where users have total freedom when placing graphical elements, in XFM the geometric characteristics of a feature are defined in the schema and enforced during a Bentley Map session. Once defined, a feature is often referred to by its geometry.
When defining a feature, the following geometry types can be selected:

---|---|---|
point-cell |

collection-point-cell |
A point collection feature represented by cell elements. |

|
linestring/curve |
A linear feature represented by a linestring element. |
|
collection-linestring/curve |
