Create a long shadow
OK, they are here to stay. So we have to find a way to construct the long shadows, although they remind us of our dear drop cap effects from the computer stone age, featured in software named "TypeStyler“ or the like.
What's good about it: it's fairly simple to do this in Illustrator. And you actually don't need to do all these cleaning processes like selecting and deleting thousands of anchorpoints along the edges, if you just follow along the technique I'm demonstrating here.
In case you're using Illustrator CS6 or CC, you can also install a plugin for this: http://63mutants.com/subc/products/opo_m01/opo_m01.php
For users of version CC2017 and up there is an even better solution (because live effect and better customizable than my solution): Astute Graphics Stylism plugin with Block shadow option
For all users of current versions of Illustrator: this needs to be made with the "classic" 3D effect.
All you need are two effects: Extrude and bevel and the transform effect. Wait - but Extrude and bevel distorts the front of your object to create perspective? Yes it does, but you can revert that.
- Take your object - if there's more than one path, group them.
- Apply Effect > 3D > Extrude & Bevel. We need the isometric presets. Select "isometric top" from the list. Important for Illustrator 2022 and higher: Use Effects > 3D and Materials > 3D (Classic) > Extrude and bevel
- For the sake of reducing the cleaning up, you need to set the rendering method. Only two methods are appropriate: "Diffuse Shading" and "No shading". Select one of them as desired. "No shading" solves another issue: colors will be changed when applying a 3D effect because of the lighting. To solve this you'll need to suppress lighting.
- Leave the Extrude Depth as is, you need to change it later anyway.
- Click OK and on to the next step.
- The result is distorted as expected and now we'll revert the distortion. Remark: perhaps you have drawn isometric inforgraphics. Then you know that it needs a series of predefined transformations to get flat objects into the correct shape. What we're doing now is simply revert these steps.
- Apply Effect > Distort & Transform > Transform. Now you need to enter a set of values to get the Long Shadow right: Vertical scaling 173,4% and Rotation 45°. The transformations need to be applied in a specific order as well, but the transform effect applies them from top to bottom, so it will be OK.
- Next open the 3D effect again by clicking its name in the appearance panel, because we'll now need to adjust the Extrude Depth to something more practical. Turn on the preview and adjust it.
- Unfortunately the 3D effect isn't that good at rendering. So now you may see any kind of errors. To get that right, we can imagine several kinds of alternative methods.
- You could expand appearance and then use a pathfinder to combine all the shapes the effect generated.
- You could also take care of this in advance and use an only slightly more complicated appearance stack.
- So at step 2 instead of applying the 3D and transform effect directly to the group you could first create a new fill for the group, move it below the contents of the group, target it in the appearance panel and then apply the effects only to that fill.
- Use No shading in the 3D effect.
- The disadvantage of this method is that the shadow is now offset from the object.
- You could solve that by either moving it horizontally and vertically in another transform effect you apply. I used Astute Graphics' plugin Stylism to move the shadow.
- Or you could expand appearance, clean the whole thing with pathfinders and then move the shadow object into its place. Make sure to turn off "Align new objects to the pixel grid" before expanding or using pathfinders, but that's a completely different issue.
You can apply this to live text and most other objects as well. Experiment with it. And in case you need to have the shadow point into other directions you need to use different values for both of the effect. The value of 173,4° will play a role in any of them.
Using "Isometric bottom" preset in the 3D effect and the same transform values as described above you can get the shadow to drop to the top left.
Using a custom rotation in the 3D effect and the same rotation in the transform effect you can get the shadow to the bottom right.
To get the shadow to the top right, you need to first apply the 3D effect with the "isometric left" setting.
Then add a transform effect with a rotation of -30° and another transform effect with horizontal scaling of 173,4% and another rotation of 45°.
Joachim Tillessen noticed that a shadow to the bottom left is missing from this page and he contributed the directions:
