How to do architectural digital marker drawing using Autodesk Sketchbook


Hello YouTube, this’s Frank from Architectural
Aesthetics. And today in this video we’ll be taking
a break from the digital marker drawing series because the royal Ontario museum drawing I’ve
been working on isn’t finished yet. Instead, I’ll be voicing over an old drawing
of mine, and comment on the tools and techniques I deployed during the making of it. Before we begin, I’d like to point out that
this prairie style residence I was rendering, is designed by Yunakov architects, and is
located in Ukraine, I’ll put the link of its coverage in the description box. The drawing is done using autodesk’s sketchbook,
formally named sketchbook pro. It is my favourite drawing software, I’ve
made numerous videos about it. However, today we’ll mainly be talking about
how to do digital architectural marker drawing with it. More specifically, what tools and techniques
we can use, to get the hand drawn marker aesthetics that is dripping with marker wetness that
can almost quench your thirst. As you can see the perspective framework of
the building is drawn in the desktop version of Sketchbook with my wacom tablet intuos
pro. And please indulge me to gripe a little bit
about the discrepancy between the desktop and the iOS version of Sketchbook. I think both of them are excellent softwares,
however, the desktop version have some ‘exclusive’ tools that are not available on the iOS platform. And these include the robust perspective tool,
which allows you to construct rigorous perspective views with ease, the french curve tools, and
the steady stroke tool. Complaints aside, the perspective tool is
extremely intuitive and pleasant to work with. For this drawing, I paid a lot of attention
to the lineweight variation, aiming to let my audience to be able to easily differentiate
bold contour lines and fine detail lines. In terms of the drawing tools, the hard pencil
tool does a great job at drawing jet-black bold lines, especially when you’re working
with large sized images that are at least 300 dpi, while the ball point pen tool gives
you unwavering, uniformly weighed lines that really mimic technical pens. It’s worth mentioning that, since the photo
reference I was using isn’t true 1 point perspective, oftentimes I had to use personal
judgment to determine the position of the lines. Here for the textures of the dry stack stone
columns, what I did was I used generalized line patterns to render roughly 1/3 of the
column, and just copy and paste the region I’d just drawn to cover the whole thing. This technique is not quite different from
what we do with texture rendering in 3d modeling softwares, in the sense that we’re stacking
seamless texture maps to cover the whole material surface. I really want to emphasize the importance
of the quality of the ink drawing, because it is the defining factor that either breaks
or makes an aesthetic digital drawing. Hence to accentuate the organic contour line
of the dry stacked columns, I spent a lot of time making it conform to the patterns
of the stacked stones. And after I’d rendered the stone textures
and marked the positions of the greeneries, I moved on to the colouring stage using the
iOS version of sketchbook. Here I really want to praise sketchbook’s
‘vintage marker tool,’ it’s safe to say that till this day digital drawing softwares
are still very limited when it comes to mimicking hand drawn qualities. The end result of the synthetic brushes, watercolour
brushes look nothing like their real life counterparts. However, I really do think autodesk sketchbook
nailed their marker tool right on the head, as the wetness, stroke overlapping of the
marker tool is just as good, if not better than the effects real world physical markers. As for the color palette, I went with the
built in Copic color library. It’s extremely versatile, and allows you
to render any common place materials. Moreover, the semi transparent nature of the
Copic colours adds more authenticity to your marker drawing. And in addition to that, sketchbook allows
you to change the hue and saturation of your layers on the fly, which is something that
traditional marker drawing can never achieve. For larger areas, I used the ‘glazing’
tool, to achieve a flat, watercolour washed look. We all know that watercolor is a beloved medium
for architectural rendering because when it comes to conveying volumes and lighting conditions,
no other medium comes close to watercolour because of its transparency. And on that note, I would say autodesk sketchbook’s
glazing tool is the closest thing you can get to mimic watercolour washes. You can see the effects for yourself, the
sloped roofs in this drawing are all done with the glazing tool. For the organic greeneries, I used the felt
pen tool to delineate the foliage, and left them filled with white, to contrast them against
the fully coloured architecture. As for the window reflections, it brings up
another advantage of digital drawing, which is its tolerance towards mixed medias. In physical drawing it would be hard or impossible
to apply gouache to a marker drawing, because of the build quality of the paper for marker
drawings can easily get crumbled under gouache. However, since we’re working with digital
canvas here, we can really do whatever we want. Hence the reflections of the nearby trees
in the glass windows, which would be very hard to render with markers, were easily indicated
with synthetic brushes. As for the lawn, I experimented with different
rendering techniques, and finally decided to render it with bold, generalized marker
strokes. Same technique for the background trees, since
they’re in the background and only included in the composition to indicate the scale of
the house, my intention was to generalize their forms as much as possible. This is indicated in the simple strokes used
to delineate the leaves. Lastly, I deployed vertical marker strokes
to indicate the background sky. The rectangular blue sky is an aesthetic choice,
because I wanted to leave some of the background as blank so that there’s a sense of contrast. However, after considering feedbacks from
colleagues, I realized the blue rectangle does a terrible job at conveying spatial depth. If I were to redo the sky again, I would use
a graded watercolour wash, instead of marker strokes. Alright guys, that wraps up today’s video,
I hope you found it informative. Please let me know your thoughts down in the
comment section, and stay tuned for next week’s video on the royal ontario museum. Bye bye.

  1. fantastic technique…love what you're doing here Frank…description is super helpful.
    would be cool to see an overhead view of you working…cheers…

  2. Great tutorials and love your work. Could you share the Basic and Advanced settings on the Vintage Marker tool with us. On Mac OXX I do not see this brush anymore in Sketckbook, but I hope I can create my own if you could share your settings of the brush you use.

  3. it's very informantive, but I had to give up watching because the rapid zoom in-out thing made me dizzy.

  4. sketchBook is my favorite app too, man.
    and it’s been for years.
    i’ve been using a Wacom intuos 4 XL since it came out.. in order to relieve my wrists from the mouse ergonomics..and also, to having a stylus-input, which is WAY more organic.
    Recently i got into Arch school and i’ve just bought an iPad (2018). i was thinking of adopting this same approach _ from sketchbook pro on the Mac, and after the base drawing, swapping to the iOS version.
    With Catalina coming to the Mac, that switch will be almost seamless. 😉
    What other workflows do you use?

    I have been looking for someone demonstrating a workflow similar to what i envision for myself, and yours has been the closest.
    Plus, you renderings are really good, man 😉 . Congrats!

    Have you tried any of the Serif apps, either on PC or iOS ?
    i come from photography, so i am used to see advanced Adobe skills, but myself, i actually only use Lightroom, so i am eager to learning how to work with Photoshop, Illustrator or InDesign, for Arch work.
    i use ArchiCAD and i am trying to get into Rhino, now..
    what Arch software are u using mostly?

    Have you got (and could you perhaps make) any videos on the entire workflow approach..from a hand sketch drawing of the concept/idea, to a 2D/3D CAD drawing , and final delivery panel ?

    thanks very much for your channel, and for sharing your work with the rest of us. 😉
