AB3160:

Logically Beautiful! A Computational Approach to Iterative

Design and Design Optimization in Autodesk® Revit®

Vincent Poon BIM Manager

Class Summary

This lecture focuses on using computational design processes by combining

purpose-built parametric families with the use of fuzzy logic and analytical data

to drive design iterations. Basic to intermediate understanding of formula-driven

parametric families is recommended for this lecture.

Learning Objectives

At the end of this class, you will be able to:

Create Revit families for computational form finding

Drive parameters using integers, formulas and conditional statements

Use environmental analytical data to optimize design

Use schedules to manage fabrication and cost estimating

Is there a right and wrong way to create a Revit Family?

Is there a right and wrong way to drink soup?

What's important is how it tastes.

Are you being efficient?

Are you being innovative?

Are you considering its life cycle?

Are you having fun?

Use Analytical Data to Drive Design Optimization

‘…an approach to applying evidence to design that neither turns

designers into scientists nor requires large-firm resources.’ Gordon Chong et. al. (2011), Design Informed: Driving Innovation
