Mass Lab: Building Masses So They Don't Blow Up

Class Summary
Want to learn how to make a bullet-proof mass that takes a hexing and keeps on flexing? (Not much rhymes with flexing, okay?) We’ll cover some techniques to help simplify that complex mass you need for your building design. Complex curves? Lofts? Revolves? Want to join them all together and still have them flex? After this class, you’ll know how to make a mass that even your newest Autodesk® Revit® software convert can’t break. Why does a bulletproof mass matter so much? Because once you start making building elements off that mass, if it breaks, you’ll have to start over from scratch. Hasta la vista to all your customizations and hosted components. So, bring your math hat and your sketchbook and let’s make some masses.

Learning Objectives
At the end of this class, you will be able to:
Learn techniques for making complex building forms parametric
Learn tricks to make your parametric mass foolproof, (well, at least mostly)
Understand how the conceptual massing editor relates to building elements
Define the workflow required to keep masses viable through the DD and CD phases

How to make a family…
For something simple, you can probably do this in your head – but for something complex that probably isn’t your best bet.
Understand what you’re modeling
Understand what you’re doing with it
Make a plan for how it will be executed
*Concepts like Nesting are equally important in masses, although shared nested masses aren’t as useful since mass floors and other properties of masses are at the instance level and therefore can’t be changed directly.

Math is in everything…
Especially complex families. Unfortunately, we don’t have that much time today. Aside from the obvious, below are some common uses for formulas in families. For reference, check out the additional materials (Fuzzy Math, AU 2010)

Rotation Rigs
Rotation rigs are assemblies you can make to help you (surprise!) rotate something
Traditional Rotation rig - unstable
Ride the Rails – stable, negative input, etc…

Workplane Based Profile Rigs
The simplest geometry rigs are typically profiles. In the massing form editor, most of the shapes you can make require at least one profile.
Generic Model Workplane Based families – good for documentation
Mass Workplane Based families – better for certain complex forms

Using Profile Rigs to create forms
Most of the time, all you have to do is pick the profile and hit create form. This works just like selecting model lines or reference lines in the host family to create a form, except the model lines in the nested profile family never vanish on you. In some cases, you’ll have to tab select to get to the profile or even individual lines within the profile to get the create form button to activate.

Mass Floors and Mass Schedules
If you’ve got a solid mass you can do some quick programming level calculations using the masses you’ve created. Worried about floor area ratios? Maximum allowable areas? Using rough area to approximate occupancy? Mass floors and mass schedules are your new best friend.

Face Based Building Components
Regardless if your mass is a surface or a solid, the classic use case for massing in Revit is as a host for face-based system families. Need a warped wall, sloped elliptical curtain systems, a multi-curved roof, or a skateboard park floor – look no farther, this is what you’ve been looking for.
