How to save system family as external loadable family

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

Cuttable vs. Non-Cuttable Revit Categories

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 visibility-settings 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

How to display beam projection in Revit plan views

Revit Beams are also known as “Structural Framing”.

Typical arhictectural (floor) plan view shows particular level with it’s cut plane set approximately 120cm from the level. Also, beams from the level above are shown in floor plans. And, here comes our first problem with Revit: what’s the easiest way to show our beams without too much manual interaction?

There are several solutions for showing beams “from above” in Revit floor plan views, each of them having their pros and cons: Read More

Display fire rating symbol with doors in Revit

In your Revit project documentation, sometimes you want to display parameters or values that are not available in Tag’s Label dialog.

Let’s take an example:

Door fire rating is a system parameter that you can use (and tag) with a door family. But, you do not want to display parameter value but rather a symbol representing value (or a range). There is no way that Revit will allow this to happen using regular Tags, that is, Tag familiy cannot “read” a value and then “decide” what graphic symbol to use. You must do this manually by using “correct” tag or tag type.

There is, however, an alternative solution. It is not coolest solution because it is off Revit’s logic (where model elements and annotations are separated) but it works.

What you need to do is: Read More
