Mario Guttman

I hold degrees in mathematics and architecture, and am a licensed architect. In addition to 30 years of practicing architecture, I have worked in software development, computer-aided facility management, and construction. I have been an active participant in industry standards organizations, and a frequent speaker in support of Building Information Modeling (BIM) and Integrated Project Delivery (IPD).

I'm mostly retired now but always interested in the advanced use of software, especially its application to building industry design practice.

WhiteFeet was my company and personal brand for consulting services and software development. I am available to discuss issues in BIM and IPD within the building industry, or anything else. I am also making some custom tools for Revit available for free.

Why "WhiteFeet"?
I just needed a domain name. Ernie was one of a series of cats with white feet.

Studies in JavaScript, HTML and CSS

I'm sort of burned out on all of the complex issues with hosted sites. I wanted to see what I could do with plain HTML, JavaScript, and CSS in a completely client-driven site. This page is just a play area.

This is also my first exploration of Visual Studio Code (as differentiated from the VisualStudio IDE) with the FireFox debugger. Both are really great!

HTML JS CSS VisualStudioCode   Link to demonstration site. It doesn't actually do anything.

Worry Bubbles - Exercise with Asp.NET Core Razor Pages

I've been studying Microsoft's Web development tools. I'm not sure if this is a good idea, but I wanted to see how it would work out to completely buy into their stack. I tried hosting with Azure as part of this exercise but found their pricing strategy too complicated and expensive, so currently have it at a cheap hosting site.

WorryBubbles is a place where you can store your worries so that you can forget about them for a while.

Unity Game Engine Development

I've been studying the Unity game engine.

MazeCats   Absurd maze with cats.

SpaceShooter   An arcade-style game with asteroids (Unity tutorial.).

Autodesk University Class on Building Data

I’ve gotten some good exposure and interaction around my class at Autodesk University last year. Fortuitously, it was recorded so you can play it here.

Or, if that doesn't work, try this.

The presentation, handout, and sample data can be downloaded from here.

WhiteFeet Revit Menu Utilities

The WhiteFeet Tools for Revit are small programs that have been created to address a specific project need or opportunity. They are always a "work-in-progress" and probably more of a proof-of-concept than a commercial product. I took the site down a few years ago because I didn't feel good about my ability to support them. Some of my loyal users objected so I put them back up. All tools are now free. At some point I plan to move some of them to an open-source GitHub site.

Downloads:   A page with various downloads.


Hummingbird is used to create native Revit objects based on Rhino-Grasshopper geometry, and import Revit geometry to Rhino-Grasshopper, and to some degree the reverse. The Grasshopper components read/write a .CSV text file that can be read by the Revit add-in Model Builder.

Downloads:   A free site on Food4Rhino which is a source for Rhino addins.

Code:   A GitHub site where the code will be maintained by the open source community.

Some Thoughts About the Industry and What I Do

The introduction of computers in the building industry initiated a change in our work process that is probably only in its early stages. I believe that many of us, who are already engaged in the details of this change, share an understanding of what it will mean. We recognize that all of our current business processes will need to be automated in some sense, and that wholly new processes will evolve as a result of this automation. From my point of view, this is a good change. My first degree is in mathematics and I began using computers while I was at the University of California in the early 1970s. After I became an architect and participated in the introduction of software to the AE design professions, I was able to recapture some of the personal interest that had led me to mathematics and computers almost two decades earlier.

I don’t see computers as “just a tool” in the context of architecture any more than one might say that a violin is “just a tool” in that of an orchestra. I believe that historians will write about how some of our generation changed our profession and the world by creating a new kind of aesthetic, based in information science. To those of us living the change, however, it is probably impossible to know exactly what this means. Personally, I take a lot of satisfaction from the details of how we implement technology. In other words, while others explore how tools like BIM are making more complex building forms possible, my passion has been with concepts of the automated design process in itself. In particular, as we introduce fundamental information-science theory, such as objects and databases, we not only increase the efficiency and accuracy of our traditional work, we also introduce new ways for our profession and our clients to think about how we create and use facilities.

We also need to be very concerned with the quality of the systems that we implement because they force others to work in proscribed ways and influence the nature of the work we produce. Our standards must be based on thoughtful, well documented, principles that are grounded in computer science but respect the history and graphic conventions of the design professions. At the same time, our process changes must reflect human needs in the way they are presented and implemented – often drawing more from the social sciences than technology. In both of these respects, concern for quality is central to both my objectives and what I have to offer. It extends into the way I analyze problems, codify solutions, develop resource material, write computer software, make presentations and teach, and manage group efforts.
