Parametric behaviour
Revit Guides
Data Management
The parametric behaviour of an object describes whether its shape, position, and orientation are designed to be dependent on other information associated with the object or the context in which it is placed, allowing for full or partial reconfiguration.
An object’s parametric behaviour can be transferred as part of the information delivery or not.
The parametric behaviour can be requested fully, partially, or not at all in the context of information exchange.[1]
To some extent, the following geometry types can allow the transfer of parametric behaviours:
- Explicit geometry defines shape as boundary representations (vertices, edges, and faces) that cannot be modified by other parameters;
- constructive geometry defines shape as constructive solid geometry based on geometric primitives and swept solids that can be modified by shape parameters.
- The definition of a single shape or an assembly of shapes through equations that provide values for shape parameters, allowing for shape modifications based on object or context characteristics, is known as parametric geometry.

Emergency Lighting in Toilet Cubicles
Summary
1. If the toilet has borrowed light and is less than 8m square:
a. There is no need for emergency lighting, however,
b. If there is a cubicle with full height door – therefore closed without borrowed lighting – then the EM lighting would be required in that cubicle.
2. If the overall toilet has no borrowed light,
a. And the WC cubicles do not have full-size doors; there should be at least one emergency outside row of cubicles.
b. If there is a cubicle with full height door – therefore closed without borrowed lighting – then the EM lighting would be required in that cubicle.
