A profile family contains a 2-dimensional closed loop shape that you can load into a project and apply to certain building elements.
For example, you can sketch the profile loop for a railing and then use that shape on a railing in your project. Loaded profiles display in the Project Browser.
To create a profile family, open a new family, and sketch a profile using lines, dimensions, and reference planes. After you save the profile family, you can load it and apply it to solid geometry in the project. The different profile family templates define specific conditions or element types, select a family template that best matches your use case.
