Lecture Contents
(CO1) Understand a working process to create a spatial, sequential process diagram
In this tutorial, you will see a working process to create a spatial, sequential process diagram. Through the process, students will learn how to use the tools and commend in Illustrator.
Create a new file
- [STEP 01] Open Adobe illustrator. (in this tutorial, I used the illustrator 2021 version)
- [STEP 02] Create a new file by clicking [CREATE NEW].
- [STEP 03] Enter the file name [Firstname_Lastname_Exercise 1 Diagram].
- [STEP 04] Enter artboard size [20in x 14in].
- [STEP 05] Confirm Color mode [CMYK].
- [STEP 06] Raster effect [300 dpi].
Save the new file
- [STEP 01] by clicking [FILE] > [SAVE] or, press [CTRL+S].
- [STEP 02] Find/create a project folder.
- [STEP 03] Click [SAVE].
- [STEP 04] Change the version to Illustrator CC by clicking the version.
- [STEP 05] Click [OK].
- [STEP 06] Click [OK] on the warning message.
Place a background image
- [STEP 01] For the exercise, you must download the image file and use it.
- [STEP 02] For your project, you can use a sketch file as a background image.
- [STEP 03] Click [FILE] > Click [PLACE] or, Press [SHIFT+CTRL+P].
- [STEP 04] Select an image file that you use as a guide for a diagram.
- [STEP 05] Click a place on the artboard.
- [STEP 06] Confirm you are using [SELECTION TOOL].
- [STEP 07] Adjust the scale by dragging and dropping the edge of the image. You may hold the [SHIFT] key to keep the image ratio. Or you can use [TRANSFORM PANEL] to adjust the size of the image. Or adjust the size on [CONTROL PANEL].

Adjust background image transparency and add new layers
- [STEP 01] Click the background image.
- [STEP 02] Adjust the value of Opacity to 30 from [CONTROL PANEL]. Or Click [TRANSPARENCY PANEL] to open the panel, and adjust the opacity value to 30%.
- [STEP 03] Double click the [LAYER 1] layer from [LAYERS PANEL]to update layer name [BACKGROUNDS].
Tip. Use a name that you can recognize better for the layer number. - [STEP 04] Click the [+] icon three times from [LAYERS PANEL] to add three new layers.
- [STEP 05] Adjust names for each new layers [DIAGRAMS], [ARROWS and ICONS], and [TEXTS].
- [STEP 06] Lock the [BACKGROUNDS] layer.
Draw the top-left corner diagram to start
- [STEP 01] Press [Z] to zoom in and out. Or you can press [CTRL+ +] to zoom in, press [CTRL + -] to zoom out.
- [STEP 02] Press [SPACE] key to handing the artboard.
- [STEP 03] Press [P] to use the [PEN] tool.
- [STEP 04] Confirm you selected the [DIAGRAMS] layer.
- [STEP 05] Start to draw the site line. If you want to use only lines without fill color, you must click the [FILL] and change the color to [NONE].
- [STEP 06] Draw the building base volume using the [PEN] tool.
Tip 1. Smart Guides [CTRL+U] is on by default. You will see the snaps while you draw, use the snap. Hold [SHIFT] key to draw 0, 45, 90-degree lines.
Tip 2. Illustrator is a drawing tool; this is not AutoCAD. That means they don’t need to be 100 % precise. Some artistic expression is allowable.
Suppose you want to draw with the isometric grid line. Please follow this step in the link. - [STEP 07] Click the object and click [STROKE] from the [CONTROL PANEL] to open [STROKE PANEL] to adjust the stroke thickness and align stroke.
Tip. You can open the [STROKE PANEL] from [APPEARANCE PANEL] or [STROKE PANEL] directly. - [STEP 08] Adjust the [WEIGHT] and [ALINE STROKE].
- [STEP 09] Draw the edge of the box using the [PEN TOOL]. You may also adjust [STROKE] as well.
Add angled texts
- [STEP 01] Click [TYPE TOOL] or press [T].
- [STEP 02] Draw and drop to add a text box.
Tip. When you create a text box, be careful with the cursor icon changes. If you want to draw a path/object as a text box, you need to click the path/object. Otherwise, you need to draw and drop in an empty area. - [STEP 03] In the text box, some placeholder will automatically fill. You need to delete the placeholders and add your text.
- [STEP 04] Edit the font, size, leadings, and more.
- [STEP 05] Mouse right-click on the text box.
- [STEP 06] Click [CREATE OUTLINES] to break the texts.
Tip. If you skip this [CREATE OUTLINE] process, [FREE DISTORT] will not be applied. - [STEP 07] Click [FREE TRANSFORM TOOL] and click [FREE DISTORT].
- [STEP 08] Drag and drop the corner of the selected text box to create angled text.
- [STEP 09] Adjust the text color/transparency/effect.
Finishing up the first diagram
- [STEP 01] Adjust the building volume fill color to hide the site line.
- [STEP 02] Adjust the site line color to indicate the volume of the site.
Note. For the exercise, you can add/develop the diagram that you are given. DESIGNERS!!
