Adobe Illustrator,
Rhino
In this final tutorial, we’ll build our 3-D Model into an isometric
site diagram of Union Square in Somerville. This type of diagram sits
comfortably between representational realism and diagramatic
simplification, making it well-suited for explanatory drawings that are
dependent upon a sense of volume.
Your initial model should look like this:
Illustrator Layers
In part 2/3 we exported Rhino Layers to Illustrator. Now, Open
Illustrator and checkout the layers:
Viewport Boundary
Study_area_05
contours_clip
3DOpenSpace
3Dsidewalk
3DBuildings
In addition, we exported 2 rendered views and a 2D-Buildings layer.
These need to be imported (drag and drop) into the main file and scaled.
For your convenience, the base file already includes these layers after
they have been scaled and put in place.
Therefore, the base illustrator file also includes these layers:
Shade - Rendered view of buildings + topography
Building - Rendered view of the buildings layer alone.
2D Buildings - The linework produced after applying the make2d
function on the 3D buildings in rhino.
Additionally, you’ll see a bonus layer called Added Elements, which
includes trees, people and cars to populate this diagram.
Adjust Stroke and Color
Turn off all layers
Go to the layers menu (View -> layers) and turn off all the layers
by clicking on the eye icon next to each layer.
Adjust features layer by
layer
Make the following adjustments to these layers:
3DOpenSpace - Fill color: Green (suggested: E7EDD1), Stroke:
None.
3Dsidewalk - Fill color: Grey (suggested: BAB9A8), Stroke:
None.
contours_clip - Fill color: None, Stroke: Brown ((suggested:
9E9A8F), Created dashed line with 2pt dash, 1pt gap. Stroke Weight:
0.15.
2DBuildings - Fill color: None, Stroke: Black, Stroke Weight:
0.25.
Follow this workflow:
Turn layer on by clicking on the left box next to the layer’s name.
You will see an eye icon populating the box.
Select all items on layer by clicking on the Layer’s circle in the
layer’s menu.
Use the Fill/Stroke tool at the bottom of the left panel to set
Fill/Stroke. The top left is Fill and the bottom right is Stroke.
If you added stroke, you will see a stroke bar at the top panel.
Click on the word Stroke, a new pop up window will open where you can
adjust dashed lines. Next to the word stroke is the line weight, it
usually defaults to 1pt, adjust to your needs. Another way to reach the
stroke menu: window -> Stroke.
Lock layer by clicking on the right box next to the layer’s name.
You will see a lock icon populating the box.
Congrats! You finished the initial set up!
Edit Buildings
Rhino exports 3D objects as wireframe curves. This is why the
3DBuildigns layer isn’t helpful for representation and its main function
is help us place the rendered buildings in the correct scale and
location. The following workflow will provide guidance on how to use the
rendered images to solve this challenge.
1. Trace Building
Turn on the buildings layer which contains a rhino generated render
of the buildings layer only as a jpeg.
select layer + Click on the small arrow by the Image Trace menu on
the top panel.
In the Pop-up Image Trace menu choose: high fidelity image and
trace. This will produce polygons corresponding for each color on the
image, including white.
Select layers, right click and choose Ungroup layers (ctrl+shift+G).
Exit selection.
Create a layer that will help us differentiate between the buildings
and the background. In the layers menu, create a new layer named:
background. Use the Rectangle Toll (m) on the left panel to draw a
rectangle the size of the viewport. Choose fill color: bright red. Place
layer at the bottom of the layers and lock.
Get rid of the white background - Select one of the white polygons
and go to the top bar ->select-> same -> Fill color. This
command will select all other white polygons, erase them by clicking
delete. Repeat process as necessary until all white space between
buildings is erased.
Name this layer: Buildings-Shaded.
2. Adjust buildings
Duplicate Buildings-Shaded by dragging this layer to the new layer
icon in the layers menu.
Name duplicated layer: Buildings-white.
Change layer order so that Buildings-white is Underneath
Buildings-Shaded.
Lock layer.
Select Buildings-Shaded and click on Opacity in the top panel. In
the pop-up click on the arrow to choose: Multiply (instead of normal)
and adjust opacity to 50%.
Lock layer.
3. Adjust environment shadow
Select shade layer which contains a rendered image from rhino of
Buildings + Topography.
Click on Opacity in the top panel. In the pop-up click on the arrow
to choose: Multiply (instead of normal) and adjust opacity to 50%.
Adjust Layer Order
Illustrator stacks successively drawn objects, beginning with the
first object drawn. Change your layer order to the following:
Viewport Boundary
Added Elements
2D Buildings
Buildings-Shaded
Buildings-White
Shade
contours_clip
3DOpenSpace
3Dsidewalk
3DBuildings
Study_area_05
Background
Make sure all layers are locked and layers 10-12 are turned off.
Add Elements
The added elements layer contains groups for 3 different elements: -
Cars - Trees - People
To start the process unlock the Add Elements group and Lock the
individual layers. For each element, follow this workflow:
Unlock layer.
Select layer and scale all elements to appropriate size. Use shift
to maintain proportions.
Change Fill/Stroke if necessary.
Place in drawing. Duplicate items by selecting the object you wish
to duplicate + press Alt + drag to where you want to locate the
duplicate.
When done lock layer.
Adjust Canvas Size and
Export
Click on the Artboard Tool at the bottom of the left panel.
Adjust artboard to view you wish to export.
Alternatively, create an artboard in the exact size you want and
scale drawing to artboard.
To scale drawing to Artboard:
Unlock all Layers
Select all Layers
Scale to the desired size.
Export: File -> Export -> Export as -> Choose type and
check the box for Use Artboard, select the artboard you wish to export
-> OK.
