Editing Windows in Autodesk Revit

Revit Tutorial: Edit the window family to include the appropriate building features, and save a lot of modeling time.

By Dan Stine

Editor's Note: This is the first in a new series of Revit tutorials by Dan Stine, author of such textbooks as Residential Design Using Revit Architecture 2011.

The window family in Autodesk Revit can be edited to include building features such as trim, sills, and structural lintels. This can save a lot of modeling time, because placing one element instantly models the window and the other building features just mentioned. This tutorial will explain why various elements should sometimes be excluded from the window family, and describe a tricky sill condition.

Excluding elements from the window family. When working on a remodel project where windows are being replaced, utilizing Revit's phasing functionality, it is typically best to avoid placing the trim and sills in the window family. When a window family is set to be demolished, the entire family gets demolished, including the trim and sills. Often, the trim and sills do not get replaced, just the window — especially when the trim is stone. Read more »

Circles and Lines Tutorial: Step Up the Power of Parametrics

What's better than a geometric constraint in AutoCAD? Multiple constraints applied instantly! That's the magic of AutoConstrain.

By Lynn Allen

My last column covered the basics of geometric constraints — aka, parametrics — a feature added in AutoCAD 2010 and available in AutoCAD 2011 as well. In this column, I'll dive even further into the magic of constraints and introduce you to another fabulous new feature, AutoConstrain, which offers much more than meets the eye. You're going to love how easy it makes your life.

Last time I showed how you can add geometric constraints one at a time as you create objects or modify existing geometry. These constraints preserve the integrity of the geometry in case you need to edit it later. But what if you already have a drawing that is geometrically correct and you'd like to apply geometric constraints throughout the drawing to keep it that way, in case you need to edit the geometry down the road? Adding multiple constraints one by one can be very time-consuming, not to mention incredibly tedious. That's where AutoConstrain comes into play.

Let's say I have a simple floor plan where I want to add parallel and perpendicular constraints, but I am much too lazy to add them individually. No problem: I just select the AutoConstrain tool from the Parametrics tab of the ribbon and window the floor plan. Voila! AutoCAD adds as many constraints as necessary to capture the existing geometry. Read more »
