Classification of parameters in REVIT 1


To understand the functioning of Revit, the first thing we have to consider is how it works?. Revit creates elements with a structure and characteristics that you are given a series of parameters. But how are these elements classified? We have different types of parameters? What are they like? How does it work?… All these questions that we can ask when we begin to delve into the performance is what leads to this introduction in that scene.

The first thing we need to know is that Revit works with families and are these which classified these elements. Depending on the type of family that is, the element will behave differently and have different parameters. There are three major groups of families: families of system, chargeable families and families modelled on-site (on-site component).

Depending on the type of family to which belong the element will have a different behaviour of these parameters. Since not with all the parameters we can work the same way and take that information in the same way. Then, what types of parameters are?.

The first classification that we would have to do would be distinguishing between type parameters and parameters of copy.

  • Type parameters will affect all the elements belonging to the same type, within the same family. To differentiate them quickly they are those that we would find ourselves within the tab edit type.
  • Parameters of exemplary, on the other hand, will only affect an element in particular, that it will be that have active and will not affect him the rest of elements of the same family or the same type.

Already differentiated type and specimen parameters, the next step would be to differentiate, depending on the family, that is, to that large group belonged. So now differentiate between the parameters of the families of system parameters of chargeable families and in situ.

Within the families of system we can find:

  • Project parameters. They are parameters that can be added to all elements of a family. We can create our own project settings. They can vary depending on the project template that we use.
  • System parameters. They are the parameters that Revit is configured by default. These parameters will always be the same in all projects and not depend on the project template that we use.

Chargeable families, can resemble them to families, since the creation of the same and its parameters will behave in a similar way, but are not going to be able to create the same types of families. For these types of families (chargeable and on-site) we can find the following parameters

  • Parameters of family. These in turn could sort it: in those created by the user and that Revit has by default (in dependence on the type of family and the template family with which we begin the family in the case of the chargeable).
  • Shared parameters. They are likely to be charged in other projects and be recorded parameters.

With this first introduction, we begin to situate ourselves in the functioning of Revit. But is there more?. Yes, but we'll see that later.
