05 00 - INTRODUCTION

I want to personally thank you for downloading this eBook. If you have taken the time to sign-up and download this eBook then you already have the drive it takes to break the “BIM-barriers” down. We need more people like you to think outside of the box and push our software-of-choice to its limits.

Design is extremely subjective. Therefore, you do not have to agree with or like my design aesthetic to get a feel for my process. This process will work regardless of what building type, design aesthetic, or “ism” you prefer.

This eBook is not meant to be a technical manual but more of a mini-guide. I’ve taken my design process and broke it down in the simplest, systematic way I could. When I released BIM After Dark - Volume 1 the feedback was incredible. Customers who purchased the video series asked if I could break down my design process in an easy-tofollow guide. Well, here it is!

Enjoy the eBook!

00 Introduction

Many people find it very hard to believe that I, “The Revit Kid”, still start with pencil and trace. Well, I do! Obviously, I embrace technology and believe in it. But even a technology geek like myself cannot deny the free hand sketch on a nice piece of trace paper or Moleskine notebook. When looking back and trying to rationalize my process for this eBook I always start with freehand “par-ti” style diagrams. Sometimes these diagrams are in a plan view, other times they are in an elevation or section view. No matter what the view, the final version of this diagram becomes the driver of the entire building. I like

to keep this diagram on my desk throughout the entire process as a reminder of where I started. Of course, designs get refined over time and some stuff will change. The diagram above is for the example project I will be using in this eBook. It is a 450 bed hospital. The entrance loops around a reflection pool while one of the two patient bed wings reaches out to meet the pool. The patient wings face each other to shield the glazing from the sun (it is a very hot climate). If you are interested in learning how I make my hand sketches look like the colored sketch on the far right, check out BIM After Dark - Volume 1 (Video 1, 00:00:11).

Papermate - Clear Point It might just be me, but I love seeing what kind of pens/pencils people use to sketch. I guess it is similar to how I purchased a Fender Stratocaster when I was younger because Jimi Hendrix used it... Maybe not? Above, you will find my current “arsenal”. I typically do all of my sketching on trace paper and I find the pens listed above to work great on trace. The Uniball has a slight bleed to it which can make for some awesome line extensions to your sketches. I also enjoy a good mechanical pencil (remember, this is free hand, not drafting). Give them all a try! Let me know what you think!

THE ARSENAL

07

The Arsenal

You can see in the images to the right that this model is very crude. In fact, unless I truly need to, I do not use Revit’s conceptual massing. I prefer to use model-in-place extrusions. I will then print views similar to the ones shown here. Once printed, I will lay a piece of trace over them and sketch continued detail and development. I go through this process (sketching, adding a bit to the model, repeat) a few times refining my design. The sketch model gets a bit more detail because of this, refer to the top right image.

Note: BIM After Dark - Volume 3 (Spring 2015) covers how I make virtual sketch models (similar to the ones on this page).

08 02 - MASSING

In my process, I constantly go back and forth between Revit and hand sketching. Once I have a diagram I am happy with I jump into Revit for the first time. Typically, I will mass out something somewhat to scale in order to get a sense of the building 3-dimensionally. Basically, this is the virtual version of a physical sketch model.

SCULPTING THE FORM

08

02 Massing Sculpting the Form

Option B: Equal Wings

One of the great things about using Revit so early in the process and creating simple forms is the ability to study different options. I will use Design Options within Revit and place each iteration of the form in the option. Now, each of my set views can flip between the different options. For this building, I was trying to decide if I wanted to place more of the program in one tower element (Option A) or distribute the program between to two wings (Option B). Similar to a physical sketch model.

Sketch-Over Technique

As I mentioned in Section 02, I constantly work between Revit and hand sketching. One of the techniques I have used during this process is what I call the “sketch-over technique”. For this technique, I simply print out my sketch model (01 & 02 above) and lay a piece of trace over it. I then hand sketch details and further develop the project (before modelling them in Revit). Finally, I scan the trace sketch and overlap the two images in Photoshop. Now, I can color the image in photoshop if desired while utilizing the shading and model from Revit (similar to image 03 above and the images on the next page).

04

Core Element

If my design and presentation is primarily being used for exterior images (at this stage) then the original “sketch model” does not have to go to waste. I continue developing my building by wrapping the “sketch model” with real Revit walls, doors, windows, and curtainwalls (image 04 above). The “sketch model” can then be used as the “core element” for your presentations. For an in-depth video of what the “core element” is and how POWERFUL it can be check out: BIM After Dark - Volume 1 (Video 3, 00:15:12)

04 Presentation Export / Render

Now that the design has been developed between Revit and hand-sketching and the “sketch model” has been wrapped with a Revit element skin it is time to start producing images. After all, what good is a design if you cannot present your concept and sell it?

Once materials are applied, I will set up my views (if I have not done so already), add lights (if required), and render. Choosing materials, tweaking with views, and getting the lighting correct will usually take a fair amount of time. Plan accordingly.

The images shown above are my hand notes and drawings specifying what materials I plan on using for this project. I plan it out on paper before entering Revit.

Post-Processing

04 - PRESENTATION

After

Finally, my images are rendered. The final step is to make them “sexy”. Post-processing renderings and images is a must. When used correctly, Revit can create very nice renderings. But they must be post-processed to extract the details, enhance the lighting, and really impress clients. The images on your left illustrate native Revit renderings (before) and the final images I post-processed in Photoshop (after). I, perhaps like you, used to Render an image and call it finished. When I learned the techniques to create the images shown here it completely changed my opinion on Revit as a rendering tool. For in-depth videos on postprocessing, adding entourage, and creating renderings similar to the ones on this page check out: BIM After Dark - Volume 1 (Video 4)

13 05 - CONCLUSION

I hope you’ve enjoyed a sneak peak into my process. It was an interesting experience stepping back and analysing my process (a process I normally don’t think about). This eBook should serve as a guide to get you using Revit early on in the design process. Don’t forget to check out BIM After Dark - Volume 1 to fill in any of the gaps or if you are interested in creating images that look similar to the ones in this eBook.
