3D “Revolve”

A second way to create a 3D effect is to rotate your object.

When a 3D object rotates, it draws a path or profile in a circular direction around the y-axis, also called the axis of rotation.

Since the axis of rotation has been established vertically, the path that you draw, is only half of the ultimately desired profile.

An example makes this clear.

I made a drawing that consists of two objects, a circle and a square. Both are a bit modified, but remain as two objects.

Now you have the possibility to group objects or not.

After you’ve grouped, these objects remain together even when you “rotate” them.

If they are not grouped, then both objects move separately on rotation.

I am grouping these, otherwise I could not have made such a beautiful drawing, I could equally well make two separate 3D shape objects. But this just aside.

So, I have selected both the objects and grouped them, then clicked the “Effect” in the menu bar, select 3D from the drop-down menu and click the “Revolve”.

This opens the “3D Revolve Options” dialog.
The options in this dialog are almost the same options as in the “Extrude and Bevel” dialog, only you have the “Angle”, “Offset” and on which edge the offset takes place options here.

The “Angle” is the number of degrees (between 0 and 360) in the path to draw.
With the “Offset”, we define the space between the rotational axis and the path.
For example, to an annular object, you can enter a value between 0 and 1000.
But you must try all this to see the effect.

What I want to mention is that when you made the 3D shape of an object, you can always change its shape by adding or deleting anchor points.
And these are the levers for dragging.

 

Scribble

Another effect that I just want to talk about is the “Scribble” effect.
You can find this effect under the “Stylize” category.
The beauty of this effect is that you can color outside the lines with this.

To apply this effect, select the object, you click “Effect” in the menu bar, you choose “Stylize” and you click “Scribble”. By the way, I added the “Round corners” effect, which you can find under the same category, on this star that I had drawn, but this is aside.

So when we clicked on the “Scribble” effect , it opens a dialog box with several options.
When you want to use a preset scribble effect, choose one from the “Settings” menu at the top of the dialog.
If you want to make a custom scribble effect, you start from a random preset and change the options for the “Scribble”.

The “angle” controls the direction of the scribble lines.

The “Path Overlap” controls the amount of scribble lines inside or outside the boundaries of the path. A negative value cuts your scribble lines within the limits of the path and a positive value allows your scribble lines to cross the boundaries of the path.

The “Variation” box next to “Path Overlap” controls the length differences of the scribble lines relative to each other.

The “Stroke Width” controls the thickness of the scribble lines.

The “Curviness” controls how much the scribble lines curve before they change direction.

The “Variation” box next to “Curviness” controls how different the curves of the scribble lines are relative to each other.

With the “Spacing” you determine the amount of space between the corners of the scratch line.

And with the “Variation” option box next to the “Spacing”, you determine how different the amount of space between the corners of the scratch line are.
