Revit: Family Curves and Formulas

Viewers: in countries Watching now:

Have you ever tried to control the shape of a curved form in the Family Editor? If so, you know that flexing them sometimes throws you a curve ball. In this course, Paul F. Aubin explores several techniques to tame your unruly parametric curves. This includes examples of circles, arcs, arches, splines, and even complex curves like cyma moldings. The real power comes in with formulas, profile families, and proportions, which allow you to mathematically control your curves. At the end of this course, we can't guarantee you'll never have misbehaving curves, but we'll give you several useful tools to help tame them.

Topics include:
  • Creating seed families
  • Creating circles, ellipses, and arcs
  • Controlling rotation
  • Working with segmental and elliptical arches
  • Using profile families
  • Working with cyma curves
  • Using fixed proportion and scaling

Welcome

Hello, my name is Paul F.Aubin, and I'd like to welcome you to Revit: Family Curves and Formulas. In this course we're going to eplore an aspect of the Revit family editor that is not normally discussed. Namely techniques to create parametrically controlled curves. If you've worked in the family editor before you probably have a good command of the basics. Placing reference planes adding labeled dimensions, flexing. But if the geometry you wish to create is not all rectilinear, flexing gets a lot more challenging.

This is the challenge that we'll tackle in this course. In this course, I will methodically discuss how to make each curve behave in the family editor starting with simple circles and ellipses. Next we'll look at curves that take a little more effort to control like open arcs, partial ellipses, compound curves. But the real power comes in when we introduce mathematical formulas. We'll look at basic arithmetic and proportions but we'll also get a nice dose of trigonometry as well. Combining a variety of techniques, we'll explore using profile families with sweeps to create complex forms.

We'll learn to associate family parameters between nested families and also how to create families that have fixed and variable proportions all while ensuring that the curved forms flex as expected. So if you're ready to tame your unruly curves in the Family editor, you've come to the right place. Now let's get started.
