Architectural and BIM & CAD
Knowing Filters

We have all implemented Autodesk® Revit® our office workflow, but the first step to use Revit within our daily design and document process is to match the graphic standards of the documents created earlier using other CAD platform like AutoCAD®. Next, we require incorporating integrating trade coordination, quantity takeoffs, and analysis.


To leverage the underlying data in Revit, one requires exploring graphic filters. Graphic filters are easy to use and assist in knowing some of the various paybacks of investing in a BIM workflow. These tools can also support quality control and project management that provides graphical and intuitive feedback.


Filters help us in controlling the graphic projection of an object by its parameters instead of its category. Filters enable quick and effective selection and modifications in the way the objects appear from within the same category. Filters are widely used by MEP engineers as they are highly essential to graphically differentiate systems like Supply and Return, to coordinate them.


Filters are located on the View Tab or can be found by moving to the Visibility Graphics of most of the views. There are three primary sections of the filter dialog which include-


Filters - It refers to all the mentioned filters included in the project. It is like dialogs where named rule sets can be developed, duplicated, renamed or removed. Users should use a usual naming method which is briefly descriptive, so that it helps them in identifying the rules applied to the filter easily.

Categories - Categories refer to the Revit categories available which are to be used to name the filters. Categories, like schedules, control the parameters that the user gets to apply rules.


Filter Rules - Filter rules are important to define the logical statement that determines on which objects the filter will be applied. There are three elements in each set of rules: a parameter to filter by, the value to look for in the specified parameter, and an operator (equals, less than, does not contain, etc.). By using the “And” statement up to three logical statements can be used per filter.
