Linking Revit files is an essential method to collaborate on BIM project, primary, but not exclusive, for interdisciplinary collaboration.
When multiple phases are present in project model (more than one phase), phase mapping occurs. Read More
As you already know, there are three kinds of families in Revit®: system families, model-in-place families and external (loadable) families (also know as .RFA files).
Some Revit® categories are exclusively system categories (families of those categories can be created only in project environment), for example: Walls, Stairs, Floors and similar categories. There are, however, hybrids (can both have system and external families in the same category), for example Structural Foundation categories but they are topic for some other time. Read More
Having multiple instances of doors or windows often carries a problem that some of them are (intentionally or not) flipped (mirrored). Flipping doors and windows is neat option but it can bring big problems. Left doors are not equal to right doors (the same goes with windows) but Revit will treat them as they are the same (if they are of the same type). This Revit Add-in solves this problem by updating parameter value whenever door (or window) instance is changed (flipped or mirrored) from right to left or vice versa. Read More

To copy values between different Revit parameters quickly, use Dynamo script. Let’s say that we entered information (parameters values) into many Revit family instances in our project just to realize that it should be on another place (in another parameter). Or we change our minds during the project (it happens).
So, in order to do the boring task of copying parameter values to another place quickly, let’s use the power of Dynamo.
The script is simple, it just uses Element.GetParameterValueByName and Element.SetParameterByName methods to get and set the values.
All you need to do is: Read More
Changing reference level of Revit family instance can be painful, especially if you do not want to move an element, just change the reference.
For particular object it’s not a big deal, just calculate the offset value, change the level and enter new offset value, the object will go to the same place it were.
But, what if we have several, if not hundreds of such objects. On different heights (offsets) and referenced to different levels? That could take some time to adjust (re-reference). And it’s prone to errors.
Even worst case is with conduits, pipes, cable trays, ducts and similar objects which have point objects (fittings), and linear objects (ducts, pipes etc.) with or without Read More
If a family is cuttable then the family displays as cut when the cut plane of a view intersects that family in all types of views.
In Family Editor, click 
to open Element Visibility Settings dialog. There is an option called When cut in Plan/RCP. (RCP is short for Reflected Ceiling Plan)
This option determines if family geometry is shown when the cut plane intersects that family. Family can be cuttable only if it’s Category is cuttable. How can we know which Revit categories are cuttable and which are not? Read More
