3D Documents: Are They Used on 100% of Your Projects?

3D Documents: Are They Used on 100% of Your Projects?

Here are the two Sketch Renderings that changed the way I handle documentation.

Back in 2007 when I switched from ArchiCAD 9 to ArchiCAD 11, I started to explore the Sketch Rendering Engine. I very quickly fell for the Koh-I-Noor settings. Eventually I refined my images by using 11_Tech_Pencil and turning down all the noise settings to zero. It made a nice black and white hidden line rendering. Almost all of my projects had one or two black and white Sketch Renderings on the coversheet. I knew I made the right decision after the first client meeting that involved one of these sets. Sitting in the client’s kitchen, the lead architect and I discussed the design. We spent a decent amount of time flipping through all the plans, sections, elevations, and details. Once we had finished our overview, the client started asking questions. I don’t remember who flipped back to the cover sheet with its two Sketch Renderings, but once that happened, the set hardly opened again. By the end of the meeting, those two renderings were covered with notes, marks, and revisions. Trace paper was put on top of them and design ideas were furiously scribbled. The final design of the project (which won some local awards) was definitely improved as a result of the ability we had to collectively sit around the table and scribble on top of those 3D views.

That’s good and all, but I still had issues with the renderings. They took forever to create and just as long to update, especially if the resolution was cranked up. And since I lean towards perfectionism, the resolution was always high. The thing about Sketch Renderings is that they can fuzz up a design. Lines aren’t straight, details are a little hard to pick up, etc. This is great for early phases. The sketch renderings allow the client, or a boss, to look at the design and not get hung up on the unresolved areas. It’s a beautiful option to help hide some of the unresolved ‘I’ in an early BIM. But that also becomes a liability later on.

I love 3D Documents.

ArchiCAD BIMWhen I jumped from ArchiCAD 11 to ArchiCAD 14, I started playing around with ArchiCAD’s 3D Document. I almost immediately stopped using the Sketch Rendering Engine for my cover sheets and exclusively used the 3D Document to create my black and white hidden line perspectives. It’s very easy to set everything to a uniform thin pen, turn off materials, and tweak the darkness of shadows (I suggest a 25% fill with a black fill pen). The lines are cleaner, the shadows are crisper, I can add some lines or fills fairly easily if I need to do some cheating, and it’s still linked to the model. And perhaps just as importantly, the view regenerates much, much faster than the sketch rendering engine. The sketch rendering engine is excellent and I hope to investigate all its other uses (watch for an upcoming blog post on the topic), but for speed, legibility, and ability to add other information to the view, the 3D Document can’t be beat.

Simple black and white 3D views on cover sheets are just the beginning. Once you’re comfortable doing those, it’s a short step to adding these views throughout your drawing set. Start small. There’s a place for disruptive change and also for incremental steps. Begin with adding these types of drawings to your documents and you’ll be amazed at what comes next.

BONUS TIP 1:

If you set up your 3D document views on your cover sheet very early on in your design process (say once massing is figured out), you’ll have continuously evolving images always ready to print out. At first they might be too ugly to share with someone not deeply involved in the work, but I’m confident that from the first print they’ll be ready for trace paper and sketching.

BONUS TIP 2:

Another benefit of putting 3D views on your cover sheets? Look again at my Sketch Renderings and then at the 2nd and 3rd images on this link. Notice a striking resemblance between the images and the final professional photography? Setting up these iconic images in your construction documents gets you thinking about final photography from very early in the design process.

  1. Great to see you here Jared.
    3D docs are surprisingly under-used in my experience – but I definitely use them on all of my projects. One of AC’s gems.

  2. Like your 3d document, it’s much easier to read but won’t the sketch render regenerate also if you set it up that way?

  3. @Amonle, Thanks. And I agree. I think it’s just hard for people to adjust to the realization that 3D views can be so fast to generate and so simple to use. And that they can be so much more than just a simple perspective.

    I’ve also yet to show one to a client and not have them love how much easier it is for them to understand. As architects we’re all trained to read all sorts of different drawing types, so it’s easy to forget that a pretty orthogonal section isn’t always perfectly legible to everyone else.

    @Bill, yes the sketch renderings can auto regenerate as well. BUT… they take much, much longer. Seconds for a 3d document, sometimes a minute or more for a sketch rendering (at least on my set up). It’s that regeneration time that really got me to switch. Plus to annotate a sketch rendering you’d have to do it on the layout and you wouldn’t be able to snap to anything.

    Thanks for the comments!

  4. Hey Jared,
    I’ve been trying to use 3D Docs in combination with the renovation filter, to show different design options. Seems like lots of potential there, but the saved view always reverts back to “existing plan”. Maybe just a bug, but I’d be interested to know if you’ve found a workaround. Worth mentioning that I’m still working in AC15 (with 16 in the box ready to go).

  5. Jack, that’s an awesome idea. In all honesty I haven’t had time to use the renovation filters much. Oddly enough almost all of the projects I worked on in 15 were new construction! Don’t ask me how that happened in this economy…

    Maybe someone else has tried this? I’ll try to take a look next week.

  6. @Jack, Maybe try this simple solution: Go to View Map in Navigator. Then check your 3D document View Settings. On General tab page you have to set Renovation filter from Existing to an other renovation filter. Then you could save an other 3D document view (source 3D document is the same) with an other renovation filter too (if you want).

    With 3D documents, illustration is faster then using rendered images. Furthermore, dimensioning is also possible. I used 3D document to illustrate structural details and layers.

  7. Very good…! I’m going to learn about this for my drawing. Thank u for great idea.

  8. @Eszter, thanks for the advice.

    @Jack, I was just looking at this in ArchiCAD 16. It works the way it should, so maybe it was just a glitch in 15, or perhaps like Eszter suggests a step was just skipped?

    @Meidy, happy to help!

  9. it works 3D the way it should be

  10. could you please write the steps, whow you get the first black and white prespective, please give the complete datas and details.
