These days I have done some experiments in this regard and would like to share some conclusions I have reached.
certainly not something brand new or original, in fact I seem to remember that you have read on www.3dsmile.it in some tip Diego Minato aka Gjiom .
Suppose we build a housing development with residential units are very similar, we can say that share the same basic model but have some differences.
Such differences could be dealt with variations, a tool that I consider to be one of the most powerful in Revit : there will always be a master template (which could be made to the limit by only objects referred to as grids and levels) and then any number of variants of the other elements of the project (which could also be absurd for the complete models).
Much more frequently, however variations affect only a portion of the model that conivolge fewer elements (such as alternatives for entry, different arrangements of furniture and generally anything that may require solutions alternatives for both technical reasons and to allow a choice in a wider range of solutions).
variants are handled with a special panel in the command bar and once activated all the model objects that are affected have a property in multiple listing the name of the group of variants and variant where belong. The group forms part of the variant version of the object (such as furniture in an office) while the variant characterizes a particular solution.
order to work at a particular variant is necessary to act on the parameters of view visibility. In fact, once activated variants appear to them in a tab in the Properties view under the Visibility / Graphics.
Here you can choose which version to display.
This is true for ogni tipo di vista e proprio per questo è possibile creare un modello di vista che prenda in considerazione anche una specifica variante o una specifica combinazione di varianti nel caso fossero presenti diversi gruppi di varianti.
Tornando al nostro esempio della lottizzazione possiamo supporre di disporre di un modello di abitazione, che chiameremo A, nel quale attiveremo le varianti per disporre con poco sforzo di più soluzioni.
La cosa migliore da fare poi è quella di collegare il nostro modello A in un altro file contenente la planimetria generale (che chiameremo B) e duplicarne le instances.
Now, to show all the variations of the same instance of the Model A into B we use the properties of view: B variants are not present but rather the connections and for each type of file connected, you can manage the replacement of graphics applications.
If we used To properly view the models for the coordination of views with appropriate variations, in B we can retrieve information model A and obtain the correct representation of the variations in the overall model using the same method.
fact, if there are any patterns connected, there is a special tab in the properties of each view of the model B, for each instance of the template attached, you can customize via the representation of cards similar to those of A model, including variations.
As in Model A, however, so the replacement graphics operations are closely linked to the eye, hence the importance of using the modeling view that this time taking into account the replacement of the graphics related applications.
For earlier versions of Revit had to switch from a 3D view to get only the significant parameters of the view from 2009 You can select which aspects considered in the model view.
links allow you to have good coordination especially in the schedules but, alas, are very inflexible for what concerns the graphic itself, or rather it is the price to pay to have available in a lightweight model a very complex geometry: some information in the "I" BIM gotta give.
In particular I am referring to the fact that you can not interact directly with a linked file, not to change it but just to add clarity, for example, the labels of the windows, although it is possible to compute in the schedules, we can not give them the labels were missing. We should have two parallel sessions Revit and place files related to the auxiliary session, save and reload the links in the main session.
This is necessary to read all the entries that the model (as the keynote for example) and then in particular labels.
I look forward to a resounding refutation as soon as possible, these are improvements to be made to forms such as stairs, ramps and railings.
Now let's take a step further: we connect the Model B in a C model, bearing in mind che se vogliamo continuare a vedere le istanze del modello A presenti in B è necessario impostare il tipo di collegamento di A con modalità Associazione ( Revit però è abbastanza sagace per ricordarcelo).
Cosa succederà alle varianti? beh, in C il file collegato è il B e questo non ha varianti di sorta, quindi per continuare a vedere correttamente le varianti di A dobbiamo assicurarci che in B siano presenti delle viste correttamente impostate a cui riferirsi personalizzando la sostituzione grafica l'istanza B su "da vista collegata".
If we used the visa will be a breeze to go to accommodate views that interest us. Fortunately, by 2009, the links can be also seen as a reference for elevation and section. Once again for a job well done should be used with the standard view, I think that by now the basic message is clear! used models of view!
